You need to check the fuel pressure, if not enough it will run rough.

SOURCE: rough running

Computers aren't ALWAYS correct. If a code wasn't cleared after the original problem, it will read the same codes off to the diagnostic. I would remove the wire connector to each injector while it's running. If one of them makes no difference THAT is your culprit. Let me know please!

99 Jeep Cherokee Sport, 4.0L -won't start


you need to have it connected to an OBD2 machine and watch if you are missing the cam sensor showing RPMs
or if your missing crank sensors RPMs,
it could be a wiring problem or computer if your seeing the RPMs from both sensors,and the last thing i would check is hooking up a fuel gauge to the reed valve and watch what fuel pressure you have while cranking,if the cam sensor is the culprit it will turn the fuel off after the cranking.

What does the auto shut off fuse do? 92 Jeep Wrangler is having start up problems.


The auto shutdown relay in your vehicle is controlled by the computer. If the computer does not see a signal from the crank or cam sensor, it will turn off power to the relay which in turn shuts off power to the fuel and ignition system. Unlike those in many passenger vehicles, it's not connected to an impact sensor. (as jeeps are off road vehicles as well as being transportation, if they had an impact sensor, they would be prone to shutdown when traveling over rough off road terrain)
The fuses to the relay are affected by shorting or overload of any components they serve, or by a problem with the relay itself.

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.

Startin and runnin problems


Most common failure is crank sensor. Before running out and buying one, I strongly recommend that you do some further testing. Any decent manual has instructions for testing systems. Also: test both running and after it dies. (while running everything may check out as good) If you have spark when not running, check fuel filter as well!
