WON'T START!? 91 e30 M3 S52 Swap

[Lakis]

UGH:

99 S52 Running OBD1 (91 E30 m3 chassis)

The car did start and now only turns but won't start.

Here is what we've tried:

DME ECU with and without TMS chip on board. It started without the TMS chip.
All Grounds checked.
Scanner shows all sensors are operating; the cranshaft pos. sensor is working.
We are NOT getting Spark or Injection Pulse.
Getting fuel and there is (5 gallons in the tank).

When I did get it started I didn't have the MAF hooked up; I don't know if that affects anything.

help brainstorming?? Please.

what dme are you running? sounds like a ews problem

[Lakis]

It is the Red label non EWS. 21.5 injector. and throttle body is 3 " to 3.5".

thanks for responding

Red label 413? There are others that have a red label.

Who did the wiring or did you buy an adapter?

When you first started it. Did it stay on?

Sorry- I bought a used obd1 harness and I am using a TREEHOUSE adapter.

Is it a 413 DME? Could still be EWS. Sounds like it with described conditions.

When I started it, yes it ran. But like I said now it won't start. If its an EWS issue; what does that mean?

[gobuffs]

If it ran with one chip and not the other, the chip is either wrong or installed backwards.

ERROR CODE: " ECU BATTERY VOLTAGE LOW "

I have a MAROON LABEL 0261 200 413

HELP

We've made sure the notch was the same both times.

Ok- so if it is EWS what are the fixes? Don't say new ecu please...

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.

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!!!

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

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