hello everybody
i have a problem with my NP300. it won't start , there is no sound of fuel pump running when switching on ignition switch. i then pulled out the fuel pump relay. then supplied voltage direct from the battery to the pin that supplies the fuel pump, started the car. it started perfectly.
what i really found is that, there is no earth signal from the ECM. I then opened the ECM and found burned resistor. replaced it but there is no ground signal from the ECM. i attached its picture below.
i attached a picture below. the wire that supplies the fuel pump, is the yellow one(pin 15 on 48 pin plug to the ECM) but, the EWD i have shows that the yellow wire had to be from pin 14 on the ECM, that confused me but i decided to eliminate that part.
i think the problem is my #distributer, even though i have not installed the new one or borrowed it from someone.
all i want to know is, this burned resistor would it be the cause of my problem??
i did all the tests excluding distributor replacement and ECM.
