If it started when you changed everything, make sure the cap is tight, plugs are gapped correctly, wires are in right spot.

My 1995 jeep grand cherokee laredo 4.0 inline 6


Something mechanical, ignition, or fuel.
It can run rough under a load such as in gear and ok in neutral with no load. Have you checked the plugs and dist cap ?

Turn the engine to TDC, so the line on the crankshaft balancer lines up with the zero. (Number one cylinder all the way up, and it should be blowing air with your finger in the spark plug hole on it's way up. This is TDC) Note, make sure you turn it the same direction as when it is running!!!! (Turn it with a socket on the end of the crankshaft, clockwise facing the front of the vehicle) Now with the distributor cap off, the rotor should be pointed at where the number one spark plug wire goes into the cap.

1994 jeep grand cherokee laredo starting problems


Check to see if the fuel pump is running after it shuts down...could be a relay or the pump itself (overheating internally) Checked the fuel filter yet? Some crank sensors need to be shimmed. If it's too close to the flywheel even though you recently changed it, if it's too close to the wheel it can fail again. May not be the case but worth checking over. Also check the ceramic resistor on the left fender near the master cylinder if you have one. That too can cause problems.

96 jeep cherokee, inline 6 4.0... runs fine... after shut off (5-10 mins) acts like its chokeing out, wont start acts like its missing, no combustion (fuel injected) let sit for 20 mins, fires up 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.

The first thing I would do since you think it was flooded is to replace the sparkplugs, sometimes if a spark plug has been washed out with gas you cannot get it completely dried out. After you replace sparkplugs try to start the engine. If the engine starts I would still recommend that you change your oil because of fuel saturation. If your engine fails to start I would suspect that you have a bad crankshaft position sensor as it is known to give problems. The crankshaft position sensor is located on the top of the transmission bell housing on the drivers side.

92 jeep cherokee wont stay running


Check the fuel injectors and rails for clogging or maybe a seized up ECU. my only other thought is that your throttle position sensor may be shot.

Causes for no spark on 94 jeep cherokee please


Well it could be many things, But have you relpaced the dist. cap and rotor, within the last 15,000 miles or wires and plugs??? next step is the coil ? then it gets fun. like timing. but I think most jeeps with a Inline 6 have a bullet proof engine for the most part. As we all know there is plenty of semi's on the road. well the same set up is there. as an Inline Jeep. I would have to say 90% of semi's on the road are inline 6 cyl. engines. and may of them go to 1million miles.
so plugs,wires, cap, rotor and ignition coil. that is a good starting point.
