i replace the motor in my 98 JGC and it too would not start, but upon putting the motor back in the Jeep i took notice that i may have "bumped" the crank positioning sensor, so i replaced that and it fired right up, im not saying that's definitely your problem given you included no details, but its a possibility, good luck
Does it turn over? Does it have fuel, spark and compression?
hard or wont start after and during rain
sounds like a flat battery to me
no it wont fit cause ive just changed a 1990 jeep Cherokee transmission it had a 1998 jeep grand Cherokee transmission in it it broke the fly wheel and burned the torque converter up
Needs a new starter
somebody broke or didn't connect the crank sensor
Before going after the relay make sure you have enough freon in the system otherwise a/c compressor wont kick on!!!
Try replacing the camshaft sensor. Sounds exactly like the problem I experienced.
on the 4.0 jeep, if it cranks, but wont start, try replacing the crank sensor, located at the top rear of the engine, at the transmission
check the neutral safety switch. Mine does the same thing. also you might not have reverse lights.
you flooded it
probably cam positionong sensor.
Could be low battery power. Not enough to start the engine.
Honestly ,to me if it wont start, then it is a power problem! because of Pontiac's alternators and being that the car is almost 10 yrs old you should have that checked!!
battery is dead, alternator is blown, needs new distributor, blown engine, head gasket is out, could be a number of things, take it in to a mechanic
im not shure but its probably the arlam that's the 1st year they put it on and it sucks
check the cranckshaft sensor and alarm system
Try adding more gas i have added gas plus some fuil enjector cleaner it still wont crank
security lock out had same problem with our 2004 grand am
Probably a bad starter solenoid.
no, on your computer youll see an ecm number on it, you have to match that number with a number on a new computer otherwise it wont run right.
neutral lock out switch It really could be several things. It could be spark plugs it could be no gas it could be no oil, and more. it could be your battery, starter, coil.etc
ok i have a 1986 jeep cherokee it wont start from the key in side it turns over but dosent fire up an its got (gas an fire) it will start if you pull start it an it has a carb
