Need clarification on injector function...ECU? Radio suppression relay? 700

posted by  someone claiming to be Matthew on  Mon Sep 15 01:30 CST 2003 [RELATED]

Ok, in the quest to figure out why my fuel injectors have decided not to work I've gotten a lot of suggestions to check these two things, but I don't really understand how they work. So let me see if I understand-the ECU grounds the injectors to fire them, and the signal to do so travels through the RSR. IF the RSR is good it should click when the key is turned to the on position-correct? So if the RSR is good and clicking and the injectors still do not fire does this indicate a bad ECU? How can I test the ECU in order to determine whether or not it is in fact bad? Also, I tried to test the resistance/voltage/etc...on the injector harnesses with a digital voltmeter, could I have damaged the ECU by doing this?

Thanks,

Matthew
