I had a similar problem with a 2001 Mercury Grand Marquis and it ended up being a bad fuel filter. But it could be a number of different things.My suggestion would be to check the vehicle on-board computer trouble codes and go from there. Good Luck.

1997 Jeep Grand Cherokee keeps cutting off and won't start some times


I would start by going to an auto parts store and having them scan the computer for codes, even if the engine light is not on. i have heard about auto part stores saying they can not scan if light is not on. i am not sure if it is the scan tool they use or what but sometimes there could be a pending code where the computer is waiting to see the problem again before turning light on. if this is the case then ask them to scan it anyway or go to a shop and ask them to do it. the reason for this is that these trucks have crank sensor problems.

the next time is dies check for spark, remove a sparkplug wire and place a screw driver into the boot of the wire and place it near a ground, a metal surface and then have someone crank the engine and see if there is spark. if there is no spark or you got a code of the crank sensor then i would replace the crank sensor, but if you have good spark and truck will not start then try spraying starting fluid into throttle body and see if it starts and dies out if it does then fuel pump problem.

If you have a fuel pressure gauge then hook that up and crank engine and see if you have fuel pressure and how much.

I will say that this does sound like a bad crank sensor, it dies and then wont start for a while ...

I have a 97 jeep grand Cherokee, when it has sat for over an hour it takes 8-10 seconds of the starter running before it starts. If turned off after running, and started within a few minutes no problem,...


Fuel pump. The valve in the pump that stops the fuel from draining back into the tank is not working so you crank and crank until the fuel gets up front. Turn the key on but not to start for 5 seconds then off do it five times and then try to start it should start right up

My 1997 Jeep grand cherokee is running real rough when I accelerate. Now while driving it it keeps stopping but will start right back up? help???


check the cables of the spark plugs, some times it occurs that the cables get loose from its plastic retainers and touch any metal in the engine, causing missfire of the related spark plug, hence rough running of the engine. Put all cables on the retainers making sure none touches the bare metal of the engine. That should help.

97 Jeep Cherokee in line 6 dies while driving or sometimes while idling. Sometimes starts back immediately but cuts back off or won't start until you sit about 15 minutes.


there is a cranksensor at back of engine top of bellhousing i think if you lay under vehicle on drivers side looking up where transmission meets engine you will see a little bracket with wires going into can be removed with long extension on swivel little hard to get new back in place and start bolts had customers wife,s jeep it would cut-off or not start she would get a ride he would go to vehicle later in day to see what happened and it would start he would think it was just her and nothing wrong but a day or two later same senario we finally nail it with cranksensor no more problem

If you have zero oil pressure thats a BAD sign, first have a mechanic check what the engines actual oil pressures are.

My 1997 Jeep Grand Cherokee Laredo is starting to have a ''slight'' hesitation after I shut it off and re-start it again. WHen I accelerate at first it hesitates a bit. I let off the gas for a few seconds...


A slight hesitation after engine shut off due to engine running rich meaning not meeting golden air:gas ratio of 14.6:1 so fuel residue in chamber continue to burn for the last moment. The same rich fuel problem that was why you had to let gas off during acceleration. Need to Check out the O2 sensor Check out MAP sensor Good luck
