01 ram 360 gas. Mice crewed wires on injector 6 crewed thru and 4 and 8 partly crewed. Replaced connectors. Scanners indicates circuit 6 and 8 open. How do i test circuits ?

 

Noid light. You can rent one from the parts store, or, just buy 'em. Not real expensive. Plug it in to the injector in question, crank motor. See if the lite flashes.

 

Noid light does not light on cyl. 8 injector connector. Relay click when tested with test light. Is there any other test i can do or is the pcm bad? Can i swap the pcm or is it need tobe done at a garage? Any tips and advice would be helpfulthanks

 

Test the wires. Make sure you have 12 volts on one side of the connector, and the wire from the injector connector, to the PCM is good. (continuity test.)

 

I have 12 volts at the connector on one wire and continuity from the connector to the pin connection going in the control module.

 

With the engine running, and everything plugged in, can you probe that wire with a test light, and see if the test light flashes??

 

I will try that and get back to you. Using a noid light be the same test?

 

If you have one, give it a shot. See what happens.

 

I did that the other day that circuit did not flash. I checked the continuity between the pins and wire and were both good. I also checked thr injector resitence on the 4 injectors and there were pretty much the same.

 

Failed injector driver then..... Likely time for a new PCM.
