WON'T START!? 91 e30 M3 S52 Swap

[328ijunkie]

These car will run with no MAF. just not well/differently

[SwiftE30]

what did you change from when it started to when it didnt start? Im suprised it started without the MAF hooked up. i had everythign hooked up except that, and mine wouldnt start. once i plugged it in, fired right up.

Check grounds, and for reference the Red label 413 doesnt have EWS, the silver does.

Sounds like a wiring issue. It was running and now it's not. Go over it with a fine tooth comb, maybe something came loose.

ONCE again the S52 swap won't start...??

When I turn the key, the fuel pump wasn't getting any power (neither were). I jumped the fuel relay and this turned both pumps on, but the car wouldn 't start. It will crank, but won't start.

I have Fuel pressure, but no spark. Power to the coils but no signal and I have an injection pulse. Replaced DME with another but still won't start. Put original chip in not the TMS; no change/start. We have checked cps sensor obviously with injection pulse this is ok. Harness adapter seems ok.

It's not the main relay.

ANy thoughts?

Woah you need some spacers!

I did 15mm in the back and 17.5 in the front.......

Once you open em' can't return em-

I am new at this. Honestly though looking at the clearance I am very close; especially the front at full turn.

Oh well. I am psyched either way. I haven't driven the car in three years. I've had it for almost 12.

Try grounding it anyway. It's free and easy to do while you wait for the new sensor. More to the point, it'll probably continue to throw a code for that anyway if you don't take care of it, so you might as well do it now.

CAR STARTS AND IS AN ANIMAL!!!

Corrosion on Crank Sensor was the culprit.

Can't wait to post a picture!!!

THANK YOU

THANK YOU!!!:crazy::crazy::crazy::crazy:

The low battery message, if it's 1281, frequently means that the ECU is not grounded properly. If you have the brackets, install the ECU in them. If not, run a ground wire to the case. Some cars won't start without DME grounding assistance, so that's the next step I'd recommend.

Excellent- thanks for helping me out.

I DID find some green corrosion at then end of my crankshaft p.sensor. I ordered a new one. If that doesn't work I will test grounding issue of DME.

THANKS!!!!!!!!!!

What is the part number on the TMS chip? Be aware that a chip for a silver label 413 will NOT work in a red label. Your issue is that you have the wrong chip.

I just put in another ECU and the car won't start still.

NOT the ecu.
NOT the after market chip (not installed anyway).

Doug at Turner gave me the TMS chip for a NON EWS MAROON LABEL 413 ECU.

Plus- I am trying to start engine without the TMS chip installed now. The test computer is seeing the data on the TMS chip when it is installed (when I have it in the ecu).

I believe I have the correct chip= I will get you the part # though.

Any thoughts on the low battery message?

Thank you!!!
