Question about 1993 Jeep Grand Cherokee

1 Answer

1992 Jeep Cherokee

When its cold it will not start. There is no spark and fuel pump doesn't come on. If I plug it in and warm the motor it will start When you turn the key everything works but the fuel pump and spark. When it is warm darn thing runs real good never misses a beat. Seems to not work under 40deg. I have had a new coil, cap, rotor, and spark plugs.

    What about the battery is it new, it might look like there is one dead cell. And what about the fuel filter. It might be bad coolant temperature sensor too.

My 89 jeep cherokee won't. Start it will turn over


what motor? is the coil producing spark?? If so, check the fuel pressure, if the fuel pressure is low drop the tank, repace the pump and also replace the filter (located on the frame forward of the tank). If the coil is not producing spark, check for shorts or opens in the circuits as well as the IGN fuses. If there is NO fuel pressure at all check the fuel pump fuses and make sure the fuel pump is plugged in and there are no opens in the circuit

1994 jeep grand cherokee doesnt like to start when warm


Car not starting or turning over indicates towards multiple possibilities. It can be issue with battery or weak battery. But if battery checks out ok, then it can be starter issue or faulty alternator or problem with low fuel pressure or no spark at spark plugs due to dirty spark plugs or faulty ignition coil or injectors getting cracked or dirty and needs to be cleaned.


To confirm the problem, the basic troubleshooting is required.

My jeep will stall when I start it up then once it warms up it will go away. After the truck is driven a while the shaking and stalling continues. What can it be? I have replace the spark plugs 3 weeks...


You will need a multipoint check on the engine.
start with the fuel, fuel filter, fuel pump, fuel injectors and the fuel lines. Fuel problems are heat dependant and wil show up in cold or warm condition. check calibration of pump.
Now check the ignition circuit of the engine. start with the plugs- now being new- check the HT wires, the HT coils, the triggers to the coils- the ignition system.
Also check the fault condition of the ECU.

COMMON PROBLEMS
There are several things that few people know about starting cars in cold weather. 1. Check your battery to make sure it is not rusted, leaking, and has a charge 2. Jump start your battery with another car, even if you believe the battery is good, this often times will still start your car. 3. If your engine is cold, and you have an older car, ensure to get your fuel lines to the engine flushed or have fuel injection service performed 4. The engine tends to warp the same way wood does during the extreme cold, do not be afraid to continue trying to warm up the engine by constant cranks with it is cold out. Your not going to hurt the car, the worse that could happen is too much fuel will enter the carborator and cause flooding in the system to occur. Wait 20 minutes if this happens and start to crank again 5. Bad spark plugs are a major reason why many cars take a very long time to start 6. Please have your spark plugs removed and exchanged for new ones. Over time, spark plugs become fowled and prevent the car from starting even thou you hear cranking!!!

My 99 jeep cherokee wagon won't start. The motor is turning over and when this first happened it sounded like it started then imediately went dead.


check that your wires are getting spark. an ohm meter should allow you to do this if you have spark then check if your getting fuel it may be a plugged fuel filter or a faulty fuel pump.

First of all, the fuel pump is generally located in the fuel tank, not always though. Yours probably is, in did not research it. The fuel electric fuel pump turns on only when the ignition key switch is turned to the start position and then left on. A series of one or two relays along with a pressure monitor in the fuel rail delivery system may or not cycle it on and off depending on design. Enough of that. I suggest that you remove the spark plugs to see if they are oil/heavy cabon deposits.If so, professional attention is reguired. One more thing you could try is replacing the spark plug wires. the may be old/worn out/damage. This would give the engine spark a stronger spark,if worn and also replace the spark plugs.

2000 cherokee sport 4.0 hard cold starts and rough idle


Did you try changing the air breather for the motor?You need three things inorder for the engine to run well. Air,fuel,and spark.since you had a tune up and fuel flushed.I can only think of two things.First I never heard of flushing a fuel filter,you change it ( not flush it ) change your fuel filter,eliminate the guess work.And change your breather.

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.
