350z G35 Fixed P0165 IPDM blown ECM ECU ECCS CONT AND IGN Fuse No Start - No Check Engine Light 

This was a good find but for all G owners out there we have a major water intrusion problem on the passenger side bottom of windshield behind battery. Bad weatherstripping and bad location for fuse box... check all your relays and fuses in this area. Also check to see if water went down through firewall under the glove compartment. BCM is located on the kick panel passenger side. Lots of electrical issues stem from the bcm wet. I put a ton of silicone around the rubber boot behind the battery where the main wiring harness goes through firewall and down to passenger footwell. Take BCM off, open it and dry it out if wet. Even if dry tou should be able to see signs of moisture if any previous issues. Usually these can be cleaned with electronic parts cleaner and good to go. Hope this helps someone chasing gremlins 😂

Our G’s MUST be brothers. I had the same thing happen to me last night. Car drove find parked it over night come back the next day to turn the key fuse #77 blows every time. I looked at every possibility. Then I just went out and unplugged all my coils and turn the key *Bam fuse pump primed and fuse was solid. Thanks for your help. Not sure what Nissan/Infiniti was thinking powering all these things through 1 fuse. It’s like 15 things this fuse powers.

Glad you got it done and didnt give up on it.

Wow, this is an interesting topic. Very educational and why the reason I don’t tune my Q50 3.7. I love your videos and your contents. Keep riding the G37 .. love the car

Glad to see you fixed it & its good to see you back. Also consider the Concept Z R35 GTR plug n play coils for the G35 they're about the same price as stock DE coils.

Glad to see you fixed it. I got the same code about a week or two after you. Hopefully it's the same fix.

You have answered my questions. and i had the same things happen to me .. I think what helped was new coil and unplugged the ecu and battery. Reset the whole thing. I spent like 3 weeks and 500 bucks trying to fix idk what fixed it but this gives me answers

I hit a speed bump today, and it blew my #77 IPDM fuse. I didn't know what the deal was. Took me hours to figure it out. Doing research brought me to your video. Always good to see the Motordyne G! I'll probably have to find a short somewhere

happy to hear that sound again.

Not sure why the problems. I do not want to jinx myself but in 16 years + granted it only drives about 5k miles a year but battery, fluids, brakes, rotors, calipers and of course new valve covers (known to leak on the VQs) but other then that and the ripped drivers seat, the car has been a joy to own. Hope yours gets fixed. These are still one of the most fun cars to own as far as I see it....

Glad to see you back 🤙🏽 thanks to you Tyler I have a full motordyne G35 plus all the same mods you have plus tune . You definitely inspired me to go with the exact mods you have

Thank you for the videos!

I just inherited an Altima with a VQ35DE that the previous owner put ebay coils and plugs in it, I pulled the intake manifold, put OE coils and plugs in it, 2 instantly blistered and caught fire. I'm in the same boat, basically, the previous owner used shit coils, burnt out the ECU coil driver. I don't know what to say to people, DO NOT USE NO NAME products for critical components! I mean, you don't have to go full OE, but go with an OE supplier of some kind, Dorman, Denso, Mitsubishi, Hitachi, etc.

Good to see you got it figured out after all bro!

Sooo many Diagnostic Technicians on You Tube are saying "Stay away from aftermarket electronic parts. In nearly all cases, they are of lesser quality." They may work initially, but they will fail a lot sooner than OEM. I too been burnt by cheap parts from Ebay and Amazon. I learned my lesson.

Got it done 💪💪💪🔥🔥🔥👌👌👌

Mines doin the same thing I thought it was my tune I didt even think about thinkin about the coils it’s been a while I’ll try to replace em and see

Nice follow up videos! I have a 2003 Infiniti G35 coupe and the battery was disconnected over winter ( I live in the midwest) so I installed a brand new interstate battery and now my "Service Engine Soon" light came on and ran a code scanner im getting a P0165 code but it runs and starts fine. Do you suggest I check my coils and fuses too. I watched all your videos related to this issue. Any way to bench test coils. All of my coils are OEM (to my knowledge)

Glad it’s back running bro🫡

Hey were did you get the new coils? Nissian?

Oem everything on the G always

Thank you so much I literally replaced 5-6 parts, and I was about to go crazy and it was a coil pack but I didn’t even check until I saw this video. Shout out to you and your video saved my ass! Thank you again

Damn good job man! So the short came from the other side of the coils to the fuse. That does makes sense now. I actually didn't know you were using AF coils. I was ready to send you my ECU lol

Bro that happen to me. The codes for MAF/IAC kept coming when my g didn’t wanna start. Ripped the harness open and nothing wrong. All along, my fuel pump just fell out of place. The grommet was too soft to hold the fuel pump in place. Not once did I get any codes for fuel related issue.

I’m having a crank no start and also just a no start at all it will bump start and run fine but will not start with jumper cables either changed my Starter alternator cam sensors crank sensor any idea 03 350z vq35de

I let it sit in storage for like a month. My g runs and drives fine but still is throwing the code. Any suggestions?

Alright, hopefully this fixes it! 🙏

I had same issues, threw spark plugs and coil packs, fuel pump, cam and crank shaft sensors at it. Long story short The pcm got wet from infinitys crappy rubber gromet on passenger side footwell. $1,400 later she runs perfect. Check the windshield plastic rubber (weather stripping) replace it before water seeps into the power control module n frys it. Had to get a new one andvre programmed to my car. 1 month later its good and home but car runs high idle, not sure if it needs to relearn the idle Edit: car shut down randomly on highway, no rain at all. Gave a cylinder 3 misfire code. Took it to shop and they diagnosed it with their good scanner and the ecu could not connect to pcm. Do not let your electronics get wet!

I don't get it,you're problem was connectors ?

That happened to me 2 OEM best the best way to go. I had 2 blown.

I have the duralast coils on mine with ngk iridium plugs still haven’t had an issue after 20000 miles(knock on wood) however I can see why you would want oem

I'm having all these issues. But my car wouldn't start showing 2 lights. Key and the red light of a car image with key inside. And I'm always misfiring. My exhaust sounds horrible. And runs like shit. 😢

Currently fighting the same problem, hope this works I was about to send the ecu in to get repaired ima probably try coil packs first

So your ign fuse kept blowing as soon as you turned the key right?

I wish you could help me with my g35. I really don't want to get rid of it

My 2006 G is at 90k miles and so far it's just needed fluids, rear wheel bearings and brake calipers. Is there anything else that commonly fails or I should replace ahead of time?

My G has been sitting at my job for over a month. It started it drive fine when i took it to work. Ive owned this car for 5 years now and never had a problem. I think i have the same problem you have. When i put the key in it turn all the wat to acc but no crank. Still gets power to electrics. I did notice that my security still flashes and I dont remember i doing that before. I put a new starter and battery and I checked all grounding and it was good. So my question is could it be the coil packs on mine too? I have never changed them since Ive owned the car.

When I turn my lights on the dash turns off and my taillight stays on even when off And and blows my headlights fuse.

I got a no start issue on my g. It cranks but wont fire up. Battery tests fine, and I could hear the fuel pump prime. I tried to test the fuel pressure but couldn’t get any reading on it. I pulled the fuel pump and my next move is to test it directly with my multimeter. The night before it decided not to turn on anymore it had a P0165 P0152 P0171. The car had been sitting so I cleared the codes to see if they’d come back and now it’ll crank but wont start 😕

Why did you never mention the new engine lol been watching for a while

Knew it would be a bad coil. Had a friend donate an altima to the local city college because he couldn't figure it out. The short can be intermittent, and hard to find when the coil packs run on 20k+ volts

Mines doing the same. But I changed them, and it don't do nothing. The injectors won't get a pulse even though they are getting power, and my security light isn't solid

OOOOOOOOOOOOFFFF Glad you got it sorted, but sucks you went through all that mess for it to be a coil pack. I wonder if adding some sort of heat reflective tape to these might help shed some heat off em.

👍

When are you gonna supercharge it with a vortex supercharger? I've heard bad things about the stillen.

I can’t wait to hear the original Motordyne G35coupe/exhaust again that motivated me to keep and build a Motordyne G35 coupe like I have today! Get this, I called Motordyne and asked them if they had any flat style rear canisters like Tyler’s Motordyne exhaust and Motordyne said “yes” they had a sample left sitting in their shop. I offered to buy them where they sold it to me. So now, my Motordyne exhaust is exactly like Tyler’s (flat rear canister tips). And it DOES change to sound from the newer style round tipped canisters! I’m thinking to do a video for comparison… 🤔

I keep burning coil pack after coil pack in different cylinders. Maybe i have a grounding issue

Where is the tach signal or injector pulse wire in the ecm?

I noticed when I put my key on the on position to check engine light does not come on, seems like cars not communicationg with ecu

Which fuse

My motors been ticking for 3 years loudly anyone know any kind of quick fix?

Hey so I got this code after changing my spark plugs and valve cover the car was perfectly fine before what should I do?

Dude I have c1130 rn I get it to start and it dies immediately

I’m getting the same code have tried everything except change all coils hopefully this works gonna probably sell her if not

Which fuse was blown ? I’m going through the same problem.

Need some help with this code

Quick question what would you do first if you got the code PO745? Cuz it says pressure control solenoid. So most shops keep telling me to get a transmission. Would you start off doing that first?

Also what’s up with your fuel gauge?

Anybody deal with a p2135 code?

My coil pack was looking the same

My car doing the same did you find out what the problem

man i literally dealing w this now it has to be wire. replaced ecm and ipdm still not getting power at datalink etc

i have the same issue, changed a bunch of stuff(ipdm, fuel pump, postive battery terminal/fuse) and i tested all my coils and they test good, my car does a crank no start, it just died while driving, super frusterating

I’m having the same issue I stay in Carlsbad

Where is the g37 community I need help

3:30 NO F**KIN WONDER TYLER’S engine stands up to the abuse he puts it through at 190+k miles!!! He got a replacement engine stock from Nissan due to the oil consumption issues. Cause here I am with my 2006 G35 where my original engine blew at 225k miles with oil smoking getting worse from 150k miles ; then over this past winter, I rebuilt my RevUp engine. Only now, can I drive my engine the way Tyler does without oil blow by. No wonder his shit is MINT.

Wow this video is crazy smh bro bad coil packs did all this smh the G always vomits out aftermarket everything

How on earth did you get a free engine due to oil consumption my 03 burns it like a bitch

I got codes P1168 and P0420 what can do to fix them. I have test pipes and Z1 cat back I just replaced all 4 O2 sensors.
