Crossfire Can't CRANK? (Part 1 - Beached Whale for a YEAR?) 

NAG1 transmission. If the transmission control module is not online then that is a no-crank. The neutral safety is the same as the transmission fluid temperature line, the line is grounded when not in gear (reverse or any forward gear gives temperature reading). Check fuses and then TCM and ABS powers and grounds, they might share the same fuse. Brake signal might come from ABS while the neutral safety signal would certainly come from the TCM on a NAG1 so if the TCM is offline you get no-crank even if the ECM is on. The harness connector on the transmission could be leaking causing transmission fluid up the harness and into the TCM. ATF+4 is designed to keep some of the metallic clutch wear material in suspension while the filter catches larger pieces, so ATF+4 might be fairly non-conductive when new but will be much more damaging to electronics when used. So if its wet with oil, the TCM may be fried. There is a chance you can clean the PCB and case of all stray particles and it will just come back to life but it is probably toast if used ATF got in there.

Ivan... thanks for another head scratching issue. Appreciate your step-by-step diagnostic approach as a great learning tool for technicians.

I left one of my cars for short to ground 10 days. In the 11th day I go to the shop, found and fixed myself for an hour. With a single test lamp and wiring diagram. And all because of you and your clips I've watched. Well basically I've watched every single clip you've made. Before you I didn't know zero about electrical ... Thank you.

check for oil in the TCM connector. Oil wick up all the way to the TCM connector when the transmission connector orings fail.

I enjoy all of your repair content. You have a great scientific approach to gain the best result and you are always striving to improve, and you have! I have been a repair technician since the 1980’s for just about anything electronic or mechanical, or both. Keep up the great work.

Ivan.. I think it would be interesting if you did a video on how you organize all your scope gear-- wires, attenuators, pressure transducers and even test lights, etc.. How do you keep track of all that stuff? How do you have it organized? Is it in a bag or do you have a mobile tool box? or maybe just some of the factory cases, etc.. and even the scope itself and multimeters; not to mention tools. I've been building my kit and I'm just trying to see what the best options are for keeping track of all this stuff and yet still keeping it mobile. I found a cheap 5 zipper pouch roll up tool bag that seems to be useful; Also I might throw it all into a rifle carry pouch with all the exterior "tactical" pockets, etc.. Not sure yet what I'm going to ultimately use.. I would love to see a quick video of how you have your stuff organized. Right now mine is just all in a cardboard box. :)

Wht would I do next? I would be looking at the transmission module. I suspect that the two wire CAN bus is not doing well, possibly because the transmission module is having a moment. Not being able to get out of park is a big, big clue. You can't talk to the module, the module isn't doing anything useful, and could possibly be a contributor to the no-start.

My next check would be if the junkyard has room for it in their lot.

Ivan can entertain and educate simultaneously, and for him to do this without any measurable contribution from my side makes it even a better act. thank you ivan for what you do. (Following from northern iraq since ≈2019 😁)

Looks like a similar problem I had my 2007 Pacifica. Turns out 4 ground wires bundled together and bolted down to the chassis directly under the fuse box had ripped loose.

9:44 - Let's touch starter motor. That's when you hope that the gearbox actually is in neutral or park so that the issue isn't that the gear shifter linkage is out of sync and the car starts to take a tour all by itself in the neighborhood.

We had a 1990 model Holden VN Commodore which we got off our auntie 25. Years ago which ran the 3.8 litre Buick LN3 engine from the 1980's in its. It had a crank no start issue which was caused by the strain on the wiring harness connector on the crank angle sensor which over time caused a high resistance join within the crank angle sensor while the engine was warm but it would start after the engine has cooled down. Replacing the crank angle sensor fixed the problem & I think GM & Holden fixed it up by the 3.8 litre Buick L36 engine which my dad has in his 2000 model Holden VX Commodore

I’d check for power and coms at the other modules. Especially TCM

that thing is pretty much a mercedes sl , mb 242 engine just crappier , front sam may be problem ,check for rodent damage of wiring . check bulk head connector at trans , will leak and have trans fluid in pins and will cause weird stuff to happen ,like no starts, erratic shift concerns , wont come out of gear .. and i would check wiring at crank position , check harness around engine and injectors / coils , for loose / bad grounds or chewed wires .

Boss radio... You know this car is a nugget.

Those were basically made from the previous-generation Mercedes C-running gear than what Mercedes was offering at the time. Even so, nice cars overall. As for "no-crank", they have a "SKREEM" security module that gets flaky and can intermittently keep the car from cranking.

Nice video on another beached whale. I definitely would look at tcm and the connector on transmission. Those like to leak and the atf will wick up to the tcm in passenger foot well. I had that on a C230 Compressor coupe.

Odd that it fired up and didnt stop straight away, i thought the module was on holiday lol :-D

A awhile back I had this same issue with it not shifting on my 2002 Acura MDX.. Little trouble shooting and I found that it was just the brake switch on the brake pedal. Found one online for ^7 dollen new (free ship).. It's been working good so far, for a few months now. OEM is like 70 dollen; so I guess we'll see how long this aftermarket junker lasts. :) It's simple enough that I think it should be a fairly good copy. (I'm only 2 mins into the video).

Absolutely perfect video to prove I need to stick to old cars. The more the "clever" electronic modules, the more the expensive problems. Found this out when I worked in a GE factory making sensors. (to obtain access to VR in the early days to achieve cheaper driver education by experience). Most of the workers couldn't care less about quality or consistency. I still enjoy these videos as I find them educational even at my old age but I prefer stuff you can see work or take apart and grease. I even know where to put the coal in and how, properly ....lol

I always somewhat liked the Chrysler Crossfire when it came out. One of the cars to come from the very short lived Daimler-Chrysler merging. Lets merge some of the crappiest American made cars with some of the most overly engineered German vehicles. A sure fire recipe for success (at least for auto technicians that need steady work).

Wow, towed all the way from Indiana! That's high praise indeed! BTW, you checked all of the inputs to the pulse module, but I didn't see you check the output to the violet and white wire. Seems like the pulse module is possibly bad, among other things.

On my MDX I fixed this with a simple brake switch, but you said your brake lights are working and that the shifter has it's own module along with the transmission module. I think I'd be checking power and grounds on those next. The fact that there are no codes is suspicious though and might be the ECM. Definitely another hour needs to be approved by the customer. :) could be a long ways to go yet.

I would concentrate on the shiftlock problem, and establish if the trans module is sending out any canbus messages. Definitely remove that stereo whilst your testing, just incase as its playing up like it has insufficient power

How did it go from start and run to a crank and no start?? Did something happen with spark or fuel in that short amount of time 🤔

I’m guessing it’s something to do with a bad TCM, or something communicating into it (such as the shift lever position sensor)

I'd be looking at powers and grounds for the TCM and ABS. You had one problem with the battery to engine block ground, how many more bad grounds are left.

tcm and other components are under passenger floor and are notorious for getting wet.thats also where the radio amp is.

Before anything I’d turn the motor by hard first to see if it’s not locked up. Seen it before shop changed battery, alternator, starter.

That car looks pretty much identical to my SLK! If it’s electrically any similar, I might have some tips. If it has one, the K40 relay module often gets super iffy. The ECU also likes to blow some components, though that usually causes crank-no-start and PCM communication issues. Not sure about the automatic though, I’m only familiar with the manual! You also pretty much need a Star Diagnostics scanner on the actual Mercedes, codes often don’t show up on more universal scanners.

Sometimes the traces in the shifter get dirty from spilt drinks and dirt and it doesn't know what gear it's in...but generally there's circles around all the selections (based off jeep but still Chrysler junk)

Until the TCM is online that car is not going anywhere. I would start there.

IIRC that Chrysler Crossfire was based on the Mercedes-Benz CLK while Chrysler was owned by Daimler-Benz. Chrysler had several vehicles/components that were based in M-B vehicles. Before the 300/Charger/Challenger ended production they were based on the old S-class chassis. I think even some Ram pickups had M-B transmissions. For not being on the road for a year, that car started and ran well. I hope this repair is "no parts required because I doubt you would find parts for that car. GREAT VIDEO!

Had a chrysler 300 couldnt move the auto shifter in the center console. Inspected all parts in the complicated shifter handle base, and found a tiny pink plastic molded part that broke and lost a very tiny spring. Redrilled the plastic part, inserted the spring and the shifter worked

Thanks Ivan!

I’d check the Tom for powers and grounds and communication line with Pico if powers and grounds are good. Car ran seemingly fine which tells me crank and cam sensors are likely working. My guess currently is TCM is causing the road block.

I'm liking my '65 Corvair more and more. Electrical system has about eight fuses! Eight.

i would go to the shift lever assembly next because it is tied into the tranny module and the illumination module and brake and traction control, which are not communicating, for direction.

Well this i part 1 which means this video should be good

Hi Ivan. I had something similar on Merc SLK. No comms with ABS, shift lever and auto box, as a result it wouldn't crank. There was a relay pack of 5 built in relays under the bonnet next to fusebox. One relay was open circuit. Had to replace the full pack. You might have something similar.

I jumped power to the TCM in the relay control module in the RCM. The solenoid in the RCM will engage, but would not conduct current across it to power the TCM. I replaced the RCM and it solved the no crank issue and TCM being off line.

Some chrysler products won,t shift if the brake light switch is half stuck,but brake lights will function

As for the starter not working well the second time - I wouldn't be surprised if it's in need for some lubrication since the mechanism could be sticky and not move freely when the solenoid is pulling. Or just a new starter, erratic starter behavior is the first signs of a starter on its last legs or suffering from corrosion. And as I noted in another post - that aftermarket radio could be the culprit, you don't know if it has damaged some harness or if it was installed in a wonky way pulling power from the transmission harness.

What would I test next ??? Probably my patience because I have none.

look for blown fuse or other lack of power on the shifter lock. We had similar problem on a Cadillac CTS would not start and would not shift due to blown fuse. In our case fuse was blown due to aftermarket remote start, but regardless without power to the shifter lock the car was dead.

Check why the brake system is not showing that will be why you can't start it with the key and move the shifter leaver. Why it won't run after warming up might be that sensor you're looking at

These M112/M113 engines are notorious for crank position sensors failing (cheap and easy fix) and causing stalls or crank no starts. That would definitely be the very next place to look.

DRB3 scan tool, multiplex cable, crossfire super card for this American German cross breed….if you have a access to one, it makes this no start pretty easy to diagnose…park neutral switch is in the shifter assembly.

I think you have seen the answer. The missing brake signal for the gear shift lockout is likely not the same switch as the brake light.

When you first said it came from Indiana I immediately thought crusty grounds from the salt and sandy roads from winters. He really wants his car fixed

If it werent for Late model Dodge vehicles, youtube would have 90% less derelict vehicle content😂😂😂

Seem like you went in 2 different directions on this one. Personally, I would have focused on the TCM. And that once you had a solid crank signal, focus on the non running, which is a separate diagnostic charge

As I have found out recently if a module has no comms the problem is most likely to be the culprit (TCM) in this case Cheers waiting on the part 2 to find out.

I wonder if the aftermarket radio is to blame. I can't remember the year of this car, but if it's one of those that requires a CAN bus adapter to get "key on" power they can send some funny signals down the CAN bus if they're the wrong one or cheaply made. Great work Ivan, always look forward to your videos.

Those modules in SLKs would usually cause random stalling or no starts, I've tickled them with the soldering iron before. (typical round pin Mercedes module things) CLKs would sometimes open circuit the positive cable between the battery and alternator somewhere too, great cars 😅

That car came all the way from right near me. Looks like Whitley county IN. It’s definitely a long way, but I would do the same if I ever had one I couldn’t figure out on my own.

The best

It's strange some of the modules are offline and the radio is acting weird. Almost seems like a water intrusion or ground problem. I guess I would try to unplug one module at a time look for green crusty's and see if one of them is interfering with com signal. I may be wrong, but I have a plan!! 😂

Chrysler Crossfire ... Made in Germany by Karmann while Chrysler was owned by Mercedes.

It's somewhat normal after sitting for a year but man, those lifters were clacking super loud.

Ever consider getting a Mercedes-Benz Xentry for diagnosis, even a fake one

Ah, the Crossfire car which looks like a dog taking a poop

i would check the grounds on those modules tht are off line with all the dash lites on when you had it running because you had to give the block a new ground source

Why would a shop replace the battery twice when a simple test would have determined whether or not the battery was good and the alternator was charging? Even I know how to perform these tests.

the ecm fuse and the tcm fuse even pull the fuse to the abs modal ! then i wold check ( with the batt unplug if you have close to 60 om +/- 3 at the DLC ! let say it 40om will then you have to find the modual or brokering wires that brought it down ! You might say why simple one or more modal may bring down the whole network take it from me networking is Not eazy to figer out !

Would check the shifter lock if not adjuster right the inputs will be right for crank but signal from trans will not be if you don’t hear the shifter lock move when you press the brake pedal it might be moving but not enough for trans lock

Good ol chryler, probably a groung issue. no matter what the customer will have it back and running soon

Shifter issue perhaps.

Woo Hoo, another PHAD video. 💖

Also, whilst in live data, does the shift level position sensor show up in the engine ecu data

Amazing how people pay top dollar for what is actually junk in a few years. Pure liability.

Could really go down a rabbit hole but I'm wondering about power & ground at the TCM. Also what doesn't the can signal look like?

I would test this cars ability to be pushed off a cliff or it's ability to resist fire😂!

My observation is that this vehicle has multiple issues. A crank no start condition when hot (ckp sensor maybe) & an issue related to the shifter stuck in park which causes a no crank. Looking forward to part 2.

Hi Ivan, I have similar problems with my 99' MB SLK230. It's a no start but will crank 3 times. CAN is at 120 ohms. I'm assuming I can still measure the Ohm's between the HI and LOW with the modules powered down by the K40 relay? I unplugged the ECM and the Ohm reading dropped to OL. Where's the other resistor? Your videos and know how are so helpful.

not being able to get the car out of park is the key to the problem......

Neutral/park start switch. I had a old tractor that would not crank, cus the transmission start switch was disconnected - way back in the 90's

The Crossfire seems to have a Misfire.....

0:46 r.c.m .... the board's have bad solider points . Ask me how I know lol. Theirs a guy in Florida that rebuilds them for around 100$ .

Hello, first of all, I am from Mexico and I use a language translator, sorry if something is written wrong, I have a 2005 crossfire, I already checked RCM and Skreem and everything is in order, everything was later After removing all the plastic from the dashboard and putting everything in its place, the car would not start again. Crank three times and turn off, im very confussed with the problem 😢

I'm not expert but I saw missing fuses when you checked the module ❗️

👍

More than likely an electrical issue. Scope the cps and compare to known good

the shop took a couple months to change the battery , damn they busy ! hope they didn't charge lot storage fee

If it’s the CPS can you hit it with a can of freeze or is it buried?

check why TCM and ESP are offline?

Oh, boy, the worst of both worlds in one, Chrysler & MB

I'd ck can line first if good then fuel pump and if good then pcm

Anybody else see what is going on here? These manufactures keep adding "modules" to the main computer to offer people more redicilous " Oooh, Ahhhh" features that cause the whole system to break down. That's how they try to justify the incredible price they charge for their POS cars. I was thinking of buying a new ride. There is nothing out there that is less than I paid for my first house, which was 53k. No thanks, I'll keep my 2 - F150's. Ones 30 years old and the other is 20. Both run very well.

Ahh, the bastard child spawn from Mercedies and Chrystler. I remember working on a few of them. It's certainly been a while though. The can bus on these was practically worthless. But enough of my ranting. My first thought is to go after the TCM. Find out why that is offline. Once you solve that, you should get the can bus back at least.

Water?

Regular Mercedes SLK just the skin different.

That looks like a Mercedes m112 engine.

👍👍

see why shifter not working.

Check for spark, fill it up with petrol not gas.. "Dog's doing no:2, Clarkson"

its not nice calling someone a dip stick car humor lol

Chrysler Cross Fire ... is a Chrysler Not Fire....

Mice love Mercedes Benz.

Ivan brake light switch is a two part system,one for the stop lamps the other for engine management/trans position lock etc might be worth a quick check without wishing to teach you to suck eggs.
