I posted this the other day thought I had it fixed.
1997 Jeep Grand Cherokee Larado, 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????1997 Jeep Grand Cherokee problem?First thing I would do would be to scan the engine control computer and see if there are any diagnostic trouble codes present. If there are codes present, they may point you in the right direction. Guessing what the fault is and putting parts on can turn into an expensive proposition.1997 Jeep Grand Cherokee problem?Well, i might say get it to a trusted mechanic, and have him run a ODBII test, (On Board Diagnostic), see if the trouble comes out on the computer... this might be a electrical problem and not mechanical...%26quot;OR%26quot;...
I had a similar problem with my Silverado a few months ago, long story short it was my fuel Filter and Fuel Pump...after both were replaced it's been like new...%26gt;have you checked/replaced your FILTER? maybe it time for a complete TUNE UP.
Best wishes, take you time and check everything twice.

Possibly the filter on the pump inside the tank is clogged to.
150,000 miles yea its a filter1997 Jeep Grand Cherokee problem?Have you checked the Technical Service Bulletin (TSB) issues published by your manufacturer? You can get a quick listing of the TSB subject titles from Edmunds:
http://www.edmunds.com/maintenance/Maint1997 Jeep Grand Cherokee problem?this is most likely not going to show up on acodes only scan. two options that I can think of is 1go throgh all the electrical plug ins make sure they are tight no bent or broken pins. with the motor running grab and slowly shake the wire harnesses if a wire is breaking or is rubbing on ground while driving this should duplicate simptoms if engine misses or dies while wiggling harness find bad wire. the other option is to drive with a fuel pressure gauge .and ascanner that can display live sensor data until it acts up watching data screen at ight moment may give you aclue also when it dies and before it restarts test spark fuel pressure and injector control signal one is not there it tthen that will tell you where to go.if I can be of more help email me through this forum with results.
