Hey guys seeking a little assistance here. Ive had this car running a few years ago with a NV m50 with no issues. Went to standalone EMS and now am back to a stock 413 ecu and cant get it running.

I am not getting spark or fuel pressure or signal to injectors.

So far checked:
- CPS 540 ohms (at ecu connector). Probing behind the connector and cranking i do get some voltage output
- Main relay gets power and switches as it should
- CEL comes on, no codes though
- Tried jumping FP relay and get nothing at the pump haven't ruled out the wiring between relay and pump but i know i am not getting gnd signal to pin85 and therefore no voltage to pin 87.
- Could not find "little black box near ABS computer to jumper green wires"
- Fuel pump works if i hook power directly to the pump and it does make pressure so the lines are correct there...

Silver label 413 ECU pin 66 is clipped which is Black/Violet wire

My adapter looks like this:
E30 E36 E30 Fn
1 25 Alternator dash light
2 - OBC Oil static
3 - None
4 12 CLT gauge cluster
5 23 Oil Press light cluster
6 22 02 relay??
7 21 Ignition power on Run
8 24 Fuel Economy cluster
9 20 Tach signal cluster
10 - OBC oil level dynamic
11 19 Service interval cluster
12 8 CEL control cluster
13 13 Fuel pump fused
14 14 road speed
15 15 Starter
16 17 Diagnostic plug
17 -
18 18 Ignition power on Start
19 -
20 -

Any input would be greatly appreciated. I know there are a lot of threads here on the issue but i haven't been able to find anything useful to my issues...

Thanks!

Is that the ECU that you ran before and it worked? Silver label requires non silver label chip to work.

I was under the impression that with the ecu pin 66 cut it would function correctly but i will try to find a non ews chip. Hopefully that works Thanks very much!!

Chip was the issue. Thanks Eduardo
