Jeep Grand Cherokee Laredo 1997?

1997 Jeep Grand Cherokee Laredo, 150,000 on it. It is giving me problems cutting off. Most of the time it happens right after it is cranked and i get on the road. It just acts like it is either starved for gas or flooded. You can feel it skip a few times and then off it goes. It will usually start right back. Weird part is, I changed the fuel pump, idle air motor and crankshaft sensor. After each part change, there was a change in how the jeep cranked and it seemed ok for about four days. Then right back to the same old problem.

When I crank it, the motor spins for several seconds before starting. After i changed the parts, it was starting soon as I turned the key, but after about four days, it was back to spinning a bit before starting. Changing the crankshaft sensor made the most difference. I really thought it was fixed, but after four days, it started cutting off again.

Never saw anything like this before. Got any ideas????

The last repair change computer is necessary change the harness Cables

You may consider buying a newer one at websites like

http://www.jeepmax.comJeep Grand Cherokee Laredo 1997?All the repairs you did assume you first made sure your ignition spark was getting to the spark plugs reliably. You have to know the basics are good before a diagnosis can be done. Since the vehicle is 11 years old, it should have had a new set of spark plug wires. If not, install them with new spark plugs if the plugs need changing too. If your Jeep has a distributor cap and rotor, change those as well.

If then it still stalls and will crank ok but not start, immediately check for good spark with the spark tester below. Check for similar owner complaints at http://www.mycarstats.com You might invest in an OBD-II computer error code reader from Actron ($60) to help you diagnose the problems.

Something about a PCM cover/fasteners shorting some wires.Jeep Grand Cherokee Laredo 1997?change fuel filter, may be more than one. check engine codes. check distributor cap for cracks, may be drawing moisture overnight. make sure fuel cap is venting properly if not could be causing vapor lock.Jeep Grand Cherokee Laredo 1997?Too old! Change it! If you need a very strong off-road vehicle choose a Defender! It's better and it lasts towsand of years!
