Alright. I took on the project of swapping my e30 with an m52 which I converted to obdi. I have a red label ecu with stock chip. But now I have a no start issue on my hands.
I have clipped #7 and #66 pins to get rid of EWS just in case, but my understanding is that with the red label 413 dme I shouldn't have to. I took the precaution anyway.
A few days before I was ready to start, I decided to open up the ECU to check which chip it had as it looked like it had been opened before. When I opened it, I saw a stock chip and put it back together. Two days later, went to start the car for the first time. Fuel pump primes but no pulse to injectors or spark. So after fighting with the potential fixes I found for those problems, nothing happened. Same problems.
I then began to question the chip again. I hadn't checked that the chip was installed correctly. So I opened the ecu AGAIN. The chip seemed to be installed backwards. I put it back the right way (indent in chip to indent in holder) and went to fire the car, hoping I had found my salvation. NOTHING.
Well. That's not entirely true. I have spark and injector pulse now. But the fuel pump doesn't run. and now I'm really lost. I've had problems with the fuel pump before so I ran through all the troubleshooting I knew for that. No power at fuse, no power at relay. Switch the chip back to original orientation, fuel pump primes and pumps but there's still no pulse to injectors or spark.
EDIT: engine cranks super strong. no problems there.
So what do you guys get from this? I tried looking for a schematic of how the chip is laid out to make sense of my problem, but no such luck finding it.
Do you think I need a new chip?
Gotta get this project buttoned up. Back to school way too soon!
