1998 Jeep cherokee just shuddered and died when i was backing out. Possible crankshaft positioning sensor or fuel pump?? For the past week it would give me troubles starting it. It would shudder and turn over and when it first started i would give it gas until it was warmed up.

Crankshaft Position Sensor is not providing the correct information to the ECU (Computer)... OR The Fuel Filter / Fuel Pump is clogged or going bad. Put a Fuel Gauge on your car and see what pressure it is and what happens after it starts to die..

U need to check the crankshaft position sensor. The fuel pump will only have power for 2 seconds I till it sees a crank signal. It' controls the asd relay which turns on your spark and fuel

See if you can hear your fuel pump go on when you first turn your key if not replace it. It should have a humming noise when you first turn your key.

sounds like your crankshaft sensor is faulty.I would change that first.

Most likely cause is the crankshaft sensor.

Sounds like the ignition coil is getting bad.

Check spark to plugs. Possible crankshaft position sensor. Located at rear of engine between engine and trans.

Most likely is the crank sensor as they are very common problems on the jeeps.
