hello. workin on a 1999 dodge ram 1500 4x4. problem with #2 injector. replace injector but still no fix.

inspect the 2 wires from injector. they both ohm' out ok.

but with the harness plug into the ecm. I was getting high resistance from the signal wire.

i found to be getting 12.50 ohm's resistance comming direct out of the ecm for the #2 signal wire terminal.

just wondering if anyone ran into this problem before or if anyone would have a wire diagram for a ecm engine harness.
