BMW E36 No Crank No Start SOLUTION: EWS Module Bypass (Works 100% for 323/328/M3) 

That's great news! I'm glad to hear that you were able to apply a similar method and that it works for e46's as well!

@@Brunboi hi sir how are u

Nice to meet you

@@Brunboi sir I have a same problem.now we are not know how to do now I need ur help sir

Hi,can you help me please.+34656560426

Awesome!! I'm really happy to hear that i could help!

Did it work

same , it would be simpler just to bridge two wires ..

I’m having the same issue any luck?

@@afterhoursgarage6586 yes, this is just a test i guess or it may work on ews1 but most are ew2 and its required to remove ews from ecu theres no way around

@@afterhoursgarage6586 yes, this is just a test i guess or it may work on ews1 but most are ew2 and its required to remove ews from ecu theres no way around

Just leave it unplugged. And it should be the same for the Z3, but I don't actually know that 100%

@@Brunboi Thank you I am going to try it I hope this car don't catch on fire lol Thanks again

@@capicapuchino5675what was the results?

It seems like the Z3's share the same EWS2 system as a regular E36 up until 1999, where it was then updated to EWS3D. Regardless, as far as I'm aware, they're both very similar systems, so I'd believe that it would work. It's at least worth a shot. Also, no need to disconnect the battery. The module only receives power if your key is in the ignition, so just make sure it's not in there when you're putting the jumper wire in. And finally, yep! You can just hang it loose. I wrapped mine up with some electrical tape to keep the wire from wiggling out while driving. If after doing this, the car cranks over but does not start, you'll have to look into deleting the EWS control bit from your DME. It's a very simple process but you'd have to buy an obd cable with an FTDI chip as well as a flashing software like MS41.

Yea Z3s are the same, basically a smaller version of the E36 3 Series except I think the rear end is shared with the E30

Did u ever figure it out?

@@nickdiaz1051 Hi, thanks for the follow up. Yes, long story short, it was the key (transponder). Finally I figured it out, and got a new key for 240 $ (in Miami) I had to avoid a couple of scammers first, that wanted to reprogram the computer, bla bla bla...but the car is running and no pb since then. Thanks again.

Do it start???

@@facundoiglesias9066 yes, its safe do that, but you can't use ews anymore

Same help please

@@tinusdevreeze6573 you figure it out

Hey, so my car is a 1996 328is. One thing I found out about after uploading this video is that in certain situations like yours, you may have to modify a control bit in the car's DME to basically trick it into thinking that the EWS module is getting power, even though it actually isn't. I've been seeing more and more people running into this issue, and messing with the DME can definitely be pretty intimidating, so I'll actually be making another video on this topic this week as kind of a walkthrough for this process!

@@Brunboi hello what is the link to the video please

@@Brunboi did you make the video?

@@Brunboi 1998 UK 328i, the bridge allowed it to crank but not run so would love the follow up video!

prying against the back of the yellow clip that slides worked for me. it takes quite a bit of force. hopefully you've already got it figured out, if not I hope this helps.

I would imagine that given your scenario, it's pretty likely that it would work. EWS usually just dies out of nowhere like that. At the very least, I'd argue its worth a shot

FYI I am throwing the EWS error code

If your car is obd2 e36 it has ews 2 which requires a chip tune i believe

That's correct!

Kontak açık konumdami olması gerekiyor.

would this work on a 96 e36 318ti

I'm wondering the same thing. Did you try it?

@@tylermarshall4243 In Theorie you could start the car without any key. In my case the complete key mechanism at the Steering wheel was broken and I ripped it all out. I startet the car by turning this orange key lock thing (I don't know how it is called) with the screwdriver but have to insert a key in this ring receiver thing. Now with this trick my car starts just by turning the screwdriver in this orange key lock thing and without any original key at all.

@@4bl0xx30 thanks so much for the reply! The affirmation I needed to dive in.

@@tylermarshall4243 Youre Welcome. I hate it when nobody answers to questions. Especially people who try something like this fix from that video. Thats why when I see stuff like this and have even tried it I try to write down my experiences. Greetings from Germany.

​@@4bl0xx30thankyou man you have saved me so much time going insane lol, I've got a euro 328i so you being in Germany has cemented this...

Yeah so the yellow plug is for the EWS2 module, which was introduced in 1996. OBD1 E36's will have EWS1, which is likely what you're looking at. Something worth checking for you if you haven't already is the starter relay, as that going bad generally has the same symptoms as an EWS2 module going bad

Did you figure out what it was? I’m having this issue on my 94 325 and it’s driving me insane

​@@Clocktowerdreamhousee a 94 will start if you connect the 2 thick wires behind the glove box with no key

I would maybe recommend checking the crankshaft position sensor, as that can cause a similar crank but no-start condition even if you have both fuel and spark.

Brunboi problem is I DID replace that and the cam sensor too

Shoot, yeah I really am not sure what your root cause would be then. I don't have enough experience working with fuel systems to be able to provide much more diagnosis then that. Sorry about that. I'd be curious to hear back and see what you found the issue to be though (if you've been able to find it yet)! It could help others or even me if I ever run into the same issue you have

You ever find out the issue? I’m going through the same issue as you. Cranks but no start even with start fluid. Already changed cam/crank sensor. Really stumped

Thatbmwguy 12 sorry I just saw this and for my car it is a 96’ so you need the key with the transponder chip and all the DME components ( dme , ews module, and key ring antenna) to be in working condition so I took all of it out from my other 96 328is and swapped it over and still nothing so sorry to say I’m stumped as well !

I would definitely take a look online to see if people have been able to successfully jump the EWS3 module like I do in the video. If it's possible with EWS3 as well, then I'd definitely recommend trying it and seeing what happens

Have a 2004 x3, same issue. How did you resolve?

put them together with a wire nut. it’d be the same thing as in the video essentially

Same

Did you figure yours out?

Same with mine..

@@benwhite8844 you figure it out?

update?

Built m52 motor, turbo, walbro 450, rpd22 tune, and much more. Got it non running, said it was just the fuel pump. Changed it to the walbro and it wasn't

Hmmm okay so to me it sounds like maybe you're dealing with a situation where your ecu thinks that ews exists, but because it isn't validating the signal, it won't let you crank. One solution for that that I've seen is changing a control bit on your ecu using your own tuning software such as romraider. The problem is that i'm not sure if you'd technically be able to do that without messing with your current tune

If you look up something along the lines of "ews delete romraider" you might be able to find some info that could help. Car sounds like it'll be a complete riot once you're able to get it started though haha. For sure planning on turbo'ing mine in the near future

@@Brunboi That's the thing. If the ecu is tuned, they have to have deleted the ews right code right? And me and my buddy actually downloaded romraider a while back because we wanted to do our own tune, just never really went through with buying the software since it didn't start.

@@Brunboi Also, pretty sure you're supposed to connect the laptop to the obd2 chord in order to use Romraider correct? If that's the case, my obd2 port isn't reading

Did you fix it?

⁠​⁠@@stormkaandorp6194yes I did get it started after doing a lot of troubleshooting. My workaround is I must plug the EWS back into place then I joined the two big wires together as in the video, but from behind the plug. For some reason it won’t start if the EWS is not plugged in…even with the two big wires are joint.

@@cya3651if I do the same it will put on the starter, but i have no spark

@@stormkaandorp6194 Sounds like your car had the same problem as mine . The problem with my car is the EWS is bad and the camshaft sensor is also bad. So when I bypass the EWS, the car cranks, but will not start, it acts like there is no spark or no fuel. This is because the camshaft sensor was bad. The way I test to see if my car got spark or fuel is to spray some starter fluid into the intake and start the car. If the car starts, that means you get no fuel. If the car does not start, that means you got no spark. I replace the camshaft sensor and my car started right up. Make sure when you remove the old camshaft sensor You also remove the rubber O-ring. When you reinstall the camshaft sensor, replace the O-ring also and make sure it is installed all the way in. Otherwise the sensor will not be able to read the camshaft correctly. If you’re not sure, just refer to RU-vid videos on how to install it. Good luck.

Did you figure this out. I have the same model 318is

you figure that out - sounds like my issue and im here surfing for a soloution

But it did work! I did this due to the install of a turner Motorsport chip. The car would crank but not turn on and now it does

It should work, yes.
