Truck has been running excellent till this morning. Started right up run smooth for about 30sec then died. Changed out the PMD with my spare, nothing. Cranks over good. No fuel at injectors. Same problem as before(see wont start). Pulled fuel shut off relay and bypassed it .Works the lift pump but stil no start. Fuel shutoff sol clicks when energized. Fuel at T valve. What else would shut off the fuel? Main computer? Replaced Fuel relay no change.

Back to the same thing,check for codes,check fuses,check for power at the shut off sol [key on] check ext harnass again and connectors,check engine harnass and connectors,check grounds at pass rear head.
Get yourself a GMTDScan tool for this truck[saves you a whole pile of guessing]
 
PMD ext cable. Not good. Put PMD at IP and it started right up. Put it back on the ext cabe and ran for 3 min then quit.
 
is there a cdn supplier for the ext cables? and not Edam.
No problem I just orderd from Leroy.
