E30 S50 no start - no spark/no fuel

Now I know this. Just seemed lame as fuck to me.

Yea, my m42 years ago did this, dug into stuff to find pointless wiring lol

I don't think the OBC relay will be my issue, Im getting 12v to the main relay and my ICV buzzes and everything that the main relay turns on has power... just no FP relay action :(

You can test the functionality of the FP relay by using a piece of wire to ground the 86 pin on the relay. This is what the DME does to trigger the relay. If the pump kicks on, the relay is good and the issue is related to the DME.

In my case, the DME was not triggering the FP relay because EWS was telling it not to. :hitler:

Solved?

I have the exact same problem. The E30S50 cranks but won't start. Double checked all wiring, grounds, relays, fuses, chip for ews, and dme is good. How did you solve your problem? Thanks in advance.

Will PayPal $ to someone with an answer

Anyone in Wisconsin who knows the e30s50 swap please help. Crank but not starting. In addition to my last post I got a new red label dme and new engine harness and still having issues. I live in Appleton, WI. I am serious and will PayPal money or pay cash to the person with answer or help.

My friend had a the same problem! At first It would crank but wouldn't turn or run I should say! And all of sudden it would even crank anymore! Everything was check for connection and re checked again! The problem was in the ecu the war chip was not making full contact ! Problem solve! I would recommend to check your ecu and programming ! Good luck !

The fuel lines are one of the easiest mistakes that can be made. Check your fuel lines. If you pressurize the tank, you will find the "return" line. The feed line is the line that is connected to the fuel filter near the back of the car. The feed line needs to go to the fuel rail closest to the firewall.
Hope this helps
