    i have checked all the pins and cleaned them and i zip tied it together to be sure it was secure,i have not tried wiggling it to see if it will shut down,i will try that asap.

    cps? what is this?

    crankshaft position sensor

  • Richard Scordino May 11, 2010

    Actually, while I was writing my reply, I was thinking that either cps or coil pack was failing. Test carefully before buying anything though.

    You first need to establish that all connections are clean and secure. Unplug the harness and look at the connector pins to make sure they are clean. There are specific tests you can do on components that will give you an idea as to if they are good or not (get a manual for specifications)
    Also remember...sometimes moving harnesses tell you that there is a poor connection, other times, you are just doing "busy work" while giving a partially failed component time to cool down and resume function. Can you wiggle the same harness and get it to stall? That would indicate that there is a connector problem.

SOURCE: 1999 4.0L Jeep Grand Cherokee shuts down after 20-30 minutes.

I'd suggest the ignition control module, however I'd have a certified mechanic check it out just in case...

Had similar problem with 96 Jeep 4.0L engine. Tracked it down to the connector for the distributor pickup. Spliced in another connector and hasn't stalled since. Also, have you had any codes? Easy way to check on Chrysler products: turn key on, off, on, off, on (not starting) and watch the 'engine light' on the dash. It will flash off/on. Count the flashes with short pauses between and longer pauses between code. When you get a 5 count and 5 count, that is the end. This may also help

SOURCE: 1996 Jeep Grand Cherokee Laredo was not firing but

Chk the battery ground cable, Remove and clean. Then chk your charging system at the battery. Should charge between 13.6 and 14.2v If it is charging above 14.2 your alt is barely charging, The further below 13.6 the more amps the alt is putting out. Make sure you battery has adequate water in it. A battery will rejuvinate itself after it has gone dead after sitting awhile,but only enough to last a few minutes. Turning on you headlights would kill it right then.

SOURCE: 96 jeep cherokee, inline 6 4.0... runs fine...

Try the pick-up coil that is under the distributer cap.Remove the cap and rotor button then remove the plate that is under the rotor button.Next you need to take off the relucter wheel that is in the way so you can take out the bolts and remove the pick-up coil.

Your crank sensor might be the culprit that's causing your problem. Have it checked.

My jeep Cherokee 2002 automatic wont idle. when I apply breaks it dies, now it wont idle at all so I cant drive it. starts fine. I had to free run in neutral to move it now Im scared I did more damage.

The problem I would say is in the brake booster diaphragm or booster valves in that there is a hole that is allowing air directly into the manifold when you apply the brakes. Check the vacuum line for tightness at the clamps as well. Normally a new booster will fix the problem

More likely the fuel pump

My 2002 jeep grand cherokee wont start at the first try some times it takes up to the tird try to start the engine

If your suv idles correctly and runs fine, there's the chance that your fuel pump's check valve is bad. This valve prevents the fuel line to drain emty after turning off the vehicle so now when you try to turn it on again you have to wait till the fuel pump fills the fuel line completely to be able to "feed" the engine. Hope I was clear.

2002 jeep grand cherokee with 4.0 engine will die but restart

I do not know what the error codes mean but know that When I has the sme problem with my jeep it was the fuel pump. What happens is when it heats up it es less and less fuel and chokes the engine. When cold it runs better. remember gas in the tank helps cool the pump but sounds like your pump needs replacing as it is starting to give out.

1998 jeep grand cherokee, with 4.0 6 engine will run fine most of the time. then it will be hard to start, miss, and die. then when it will start will run rough, die, and then it run fine for a while. i...

OK...if someone gives me a bad rating on this, I'll be really annoyed...
saw off the "fixed" hold-down on the distributor and use a chevrolet smallblock hold-down. Once re-installed turn distributor ccw about 1/4" or slightly more. If I'm correct, engine should run fine after that.
