Redoing the post for the Motronic/SETA swap
So, my car won't start. I just swapped a new harness and a new engine. It will only start if I prime the fuel pump and it runs for a second. If I put back the relay, it doesn't start. I don't even hear the fuel pump. If I try to jump the ECU relay, it doesn't start either. I checked the Crankshaft position sensor and it was damaged. I also grounded the oil pan to the original spot but the ecu is wired to the battery tray metal, where the old 02 sensor was. I saw motronic cars had it in the stru tower. Am on the right path? Why will it run when primed manually, doesnt the dme also cut ignition when the sensor is bad?
