My 1996 jeep grand cherokee has trouble starting

Does it only give trouble starting in the mornings, when the engine is cold or anytime and at any temperature? Did you replace the computer with a new or rebuilt unit?

You need to check, when the jeep is cold, if the check engine light comes on when you turn the ignition switch to on, before cranking the engine. If that light does not light up on the dash immediately, then the jeep won't start until it does, which can be as short as a few minutes to as long as 20 minutes. That would be a classic sign of a bad ecu, slowly getting worse, that needs repair. Check it out and post back here in this same thread with your findings.

Hi,
I own a 96 Cherokee. Had a problem with it not starting randomly, havent ever really had any running issues like that last 40-50k every so often it will kinda bog down when you first are driving and you have to let of the gas but happens rarely and haven't pinpointed it yet. Anyways back to the starting. Have you checked the ground to the block? I replaced all my positive and negative wiring and that helped. Hop this helps at all. and good luck. Also check your vacuum lines, one running along the passenger side fender is definitely one place.
Take care,
Lee

check the fire at the coil as well as distributor if you dont have fire there when cranking then check your igniton module if there is fire? then your fuel system has shut down could be a faulty pump / filter/ or stuck injector which happens in cold weather and having just a drop or two of water in your fuel system

Sounds like a poor connection somewhere...Best time to check is when it's in no-start condition...When running, obviously whatever isn't working is (temporarily). Once you identify the system (fuel, spark etc) that's not working, check all wires and connectors for good contact and continuity.

I think you got it out of time if you take and move it around if that don't work then take it out and move the gear around and repete

Is it fuel injected or carb??? Try holding the gas pedal to the floor while turning the jeep over. This sometimes makes gas pump thru to the cylinders. Have you changed the fuel filter???? I know alot of jeeps have a fule filter with a bypass back to the tank, and sometimes the filter will be bypassing to the tank instead of the the motor. Check it out?????

10-12 volts, that is low, have the battery load tested at a local parts store like Autozone, it's free.

check the battery to make it is fully charged and also put some dry gas in the gas tank

Welcome to the forum. Your question has to many variables. Cold weather out here in Cen Cal this time of year is mid 40s. Is the problem when the vehicle is cold as in ovrernight but starts ok when it is warm? Does it crank OK but seem like it's not getting fuel? If you hold the throttle slightly open, does it start OK?
