2012 Jeep Liberty No Crank No Start - How to test PCM and WCM?
What is your question?
Hey Jeep pros!
Jeep Liberty just decided to stop cranking. Only have 50K miles.
Daughter tried starting Car. No Crank, No Start. Dash Lights and Radio on.
1) Tried Jump starting thinking Battery was bad - Battery tested Good.
2) Placed shifter in Neutral - still no crank, no start
3) Inspected starter fuse and other fuses for burnt fuses - none.
4) Swapped Starter Relay - still no crank, no start
5) Jumped Starter Relay (terminal 30 to terminal 87) with wire. Starter kicks over but engine doesn't run - should it?
6) Tried our backup Key FOB - no difference.
7) Tested using a meter pin 86 on Starter Relay while Key is turned to start and I don't get power.
Leads me to believe it is the Wireless Control Module, PCM, or ASD Relay.
I swapped ASD Relay with another one and no difference.
Sometimes disconnecting the Battery, let it sit - it would then start - other times not.
When it did start and drive, it stalled on the road twice without warning.
Thanks!
