I got this car from my friend. He took it to the dealership and they diagnostic that it need a Electronic Shifter Assy and need a brake switch.
I didn't replaced the shifter assy since it was the brake switch issue. The car started and drive with no problem until I was running a OBD2 scan while the engine was running and the engine cut off during the scan. I was able to start the car once for less than a minute before it cut off.
Current condition:
I can't get the OBD2 to communicate at all, I check the fuse for the diag port, getting no power.
I'm getting power signal from the EIS system to relay, I'm not getting ground signal from ECM to latch the relay. Bypass relay directly will turn the starter motor, no sparks.
I bought a matching ECM and swapped Immobilizer EEPROM. It still acting the same with the fan running when the key is in the start position.
I need some pointer to go from here. A starter / diagnostic port diagram would be great. It hard to troubleshoot this car when I can't scan it and with little diagram is a nightmare. Please assist if you can.
