Question about 1993 Jeep Grand Cherokee

2 Answers

1993 jeep grand cherokee wont start

I have spark, fuel, and a good charged battery.  I have alrready replaced the PCM, MAP sensor, TPS sensor, and fuel filter and fuel injectors. As well as cap, rotor, plugs, (and yes the firing order is correct) The alarm is not going off and I have checked all fuses.  I ran a self diagnosis with the key and the computer says nothing is wrong.  Does anybody have any ideas of another sensor that could be checked or replaced. This is our only vehicle and any help would be apreciated. Thank you.

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.

Location of tps and map sensor on a 02 jeep grand cherokee 4.7l


Both are attached to the throttle body. Tps is on the other end of the throttle plate shaft opposite the linkage, MAP is on the side...has small vacuum hose underneath and is flat, about 3" long. The other item on the TB is the idle air motor, next to tps.

1993 JEEP GRAND CHEROKEE LAREDO IM TOTALLY BAFFLED


Back up a minute...Do you have spark from the coil wire? (juice from coil) If so, change or check rotor and cap (wires do not all go bad at same time so unless they are wet, likely at least good enough to start engine)

Running rich. No power. 5.2 v8


it can cause it to run rich because the oxygen sensor may be getting a false reading as to how much oxygen is there....this in turn causes the pcm to add more fuel
