2000 Jeep Laredo Repair Question
Why is my number 7 injector wire not pulsating?
If you have tested and confirmed the injector is not pulsing, you either have a break in the wiring corcuit ot a faulty PCM.
What trouble codes are you getting?
I had someone to put the injector test light on it all cylinders pulsated but number 7. When tested number seven light just stayed on didn't pulsate.
If the light stays on, it means the PCM is bad and keeping the circuit grounded. This should trigger trouble codes. Do you have any trouble codes?
It could also mean the wire from injector to PCM is shorted to ground.
What is PCM and what can I do about this problem hopefully an easy fix
Power Control Module, meaing the engine computer. If it is a shorted wire or PCM, it would be an easy fix but the cost between the 2 would be vastly different. You need to check/test the wire for shorting.
Ok I will do that Thank You so much for your help
