Ok power TO the injectors is supplied THROUGH the IG3 relay and the computer supplied the ground circuit, but the computer must receive a signal from the crand and cam sensors to 'PULSE' the injectors. Make sure that one side of the injectors have 12V with the key on
If you disconnect an injector connector and connect a 12v test light across the connector ( one end of the testlight to one terminal of the disconnected connector and the other end of the testlight to the other terminal in the same cnnector) ccrank the engine the test light should Blink Do this to all Four (4) injectors and if they all blink you have either shorted injectors or plugged which is unusual for all 4 to be plugged.
But if you do not have a Blink you have to see if the computer is receiving the singals telling it that the engine is cranking over, and if the signal TO the injectors from the computer is available if so then you could have a wiring harness problem but again its so rare that all four injector wires and only the injector wires are bad don't you agee?
Please call me and I can explain this in more detail or contact me at [email protected]
Thanks Randy I believe its not tht big of a probles as everyone makes it out to be
