i have an 01 grand cherokee that would die out after turning on i have replaced many parts and it doesnt want to turn on at all
PARTS REPLACED
1. SPARKS PLUGS (CHAMPION PLATINUM)
2. COIL PACK
3. BATTERY
4. FUEL PUMP, FUEL FILTER, AND RESTRAINERS
5.PCM (NEW)
6. DIAGNOSTICS TEST, AND COMPRESSION TEST PLUS LABOR

I HAVE USED ALOT OF MONEY AND THE DEALERSHIP STILL CANT GET IT TO TURN ON!!!! ANY IDEAS ONE THE PROBLEM

 

I know it might sound dumb...but did they double check that everything got hooked up/hooked up right?

 

It would help to know what engine you've got.

 

I gather its cranking, any trouble codes, it could be something simple like crankshaft position sensor

 

Its a 4.0 and there was misfire in 3,4 but we switched the plugs....its is cranking but does not wanna turn on

 

Tested the CPS?
