Question about 1994 Jeep Grand Cherokee

1 Answer

Same problem. No sparks to the fuel pump.

We changed out the PCM, still we are not able to get the jeep to start. It will turn over.

    The jeep is still not getting any reading on the gages on the instrumental panel or to the fuel pump. During one of readings of the "Service Engine Code" the code was being read as the the computer module.

    What else do we need to check? We checked the spark plug to see if any current was flowing thru which we did see that.

    did you program the PCM the boxes comes blank u have to flash the old software to the new box.

    why did you replace the PCM, that is the last part that fails EVER!

  • Richard Scordino May 11, 2010

    There are so many other items that need testing, what led you to replacing the pcm?

Have you tried the crank sensor on the trns. bell housing. If the sensor does not work, it will not give a signal to the pcm to fire the coil.

    If your not getting power to the gauges when you turn the key then you have to check the fusible links or fuses.

1995jeep wrangler 2.5 cranks well but doesn,t start


If its cranking fine you have one of two problems either your not getting any fuel or you have no spark. When toy turn the key to the on positron but don't crank the car lean back and listen for a whirling sound that is your fuel pump. If you don't hear anything is probably not working spray some starter fluid in your trottle body if starts you now know your problem. If the pump is working you need to check for spark one way to check is pull a spark plug wire off the plug plug it into a spark tester and crank it if you don't see any spark the problem may be your ignition module. Hope this helps you

00.6v at the fuel pump


are you reading the meter right ?, less that 1 volt?
did you crank the engine and read,many car dont start the pump unit cranked.
it must be 12v or 11v if very cold and bettery volts sag a bit (1v) cranking. that is how you do this.
on some jeeps (i dont do liberty) the ASD works like this.
the 2 second rule.
TAKES 2 people to test a JEEP.
not 1.
one to crank and one to measure.
the PCM allows 2 seconds. of full spark and injections
if it sees errors,. it kills every thing, spark and fuel.
its jeep.

My grand cherokee won't start. at fist it would take 2 or 3 times to start up not it will crank all day but will not start up. I was thinking of changing the altenator and starter but now I'm...


SOUND LIKE PROBLEM IN IGNITION SYSTEM OR FUEL SYSTEM. MAKE SURE SPARK PLUGS AND WIRES OKAY.REPLACE DISTRIBUTOR CAP AND ROTOR,REPLACE FUEL FILTER AND AIR FILTER,DO A LITTLE TUNE UP FIRST TO MAKE SURE VECHICLE GETTING GOOD SPARK AND FUEL. IF NOT GETTING SPARK CHECK IGNITION FUSE.IF FUSE OKAY PROBLEM COULD BE IN ASD RELAY OR PCM.CHECK FOR FUEL IF YOU NOT GETTING FUEL CHECK FUEL PUMP FUSE AND RELAY.IF ALL IS GOOD FUEL PUMP COULD BE FAULTY OR PCM. I WOULD HAVE VECHICLE CODE SCAN FIRST TO SEE WHAT FAULT CODES YOU ARE GETTING. DONT GO BUY A LOT NEW PARTS CODE SCANNING WILL KEEP YOU SPENDING A LOT OF MONEY,CODE SCANNING WILL HELP SPEED UP PROCESS TO SEE WHAT CAUSING VECHICLE NOT TO CRANK.YOUR GASOLINE IN FUEL TANK COULD HAVE WATER IN IT PROBLEM COULD BE SOMETHING MINOR.

CODE SCAN VECHICLE FOR FAULT CODE, IF YOU ARE GETTING SPARK PROBLEM IN THE FUEL SYSTEM, CHECK FUEL PUMP RELAY AND FUSE MAKE SURE FUEL FILTER BEEN CHANGED AND FUEL PRESSURE IS 39 - 41 PSI. CHECK FOR FUEL SPARK SEE WHAT GOING ON, VECHICLE NEEDS FUEL OR SPARK TO RUN IF ONE NOT WORKING ENGINE WILL NOT START.

1999 Jeep Grand Cherokee Died while driving home


check the fuel pump fuse/relay, could be just bad enough to cause an intermittent start/no start. and check fuel pressure,spark and the crank position sensor.

Jeep won't start until a clicking sound comes from fuse box


The click you hear is the fuel pump relay. It gets its signal to energize from the PCM.If you have a faulty Crankshaft Position Sensor, the PCM will not work. Check for a bad fuel pump relay and also all of the other sensors: Camshaft Position Sensor, MAP Sensor, Idle air Control, Intake Air Sensor,etc.
