e38 standalone, no power to MAP,ECT and alll 5volts form gray connector
greetings
How do I diagnose a faulty ECM? It seems that every sensor hooked up to the gray connector doesnt have a 5v supply, also tps reads 100... could you help me, my boss doesnt want to buy a new ECM for testing.
thanks
PD...I am using a 12V source outside the car... do ECT and sensor require grounding?
