I have replace # 5 injector ran a noid light did not light up check wiring from injector to the computer all good Chrysler said the computer was bad so we replaced it still did not work also cleaned all conectors Anyone can tell me what else to look for?

 

What are you missing ? 12v or the ground pulse on the other wire? Noid light like any other light needs power and ground see which you are missing. How did you check the wires from injector to pcm any way?

 

I used a ohm meter the check the wire from # 5 injector which is brown & orange to the pcm terminal all was good the other wire which is brown & white goes to a conection in the harness which the all connect together. We had Chrysler check it they sad pcm was bad installed remanufactured and it still skip #5

 

ok you did not answer anything i asked.

 

I can not find any engine wiring diagram for the 2010 Chrysler Town & Country 4.0 what should I read on the injector wires is one of them ground?

 

Oe will be power the ground will pulse like a switch going on and off turning on and off the injector
