2004 jeep grand cherokee died on the freeway and now just cranks but won't start
Whew! Tight spot. Here are some quick and some more involved things to check. Hopefully, another responder will pitch in. A good time to call AAA.
Troubleshoot this issue step by step:
Check for Spark: Crank the engine and check if there's a spark at the spark plugs or ignition coil. If you have a spark, the crankshaft position sensor (CPS) is likely not the problem.
Fuel Pump Operation: When you turn the key to the "on" position (but not start), you should hear the fuel pump run for a couple of seconds. If you don't hear it, there might be an issue with the fuel pump or its relay.
ASD Relay: The Automatic Shutdown (ASD) relay controls power to essential components like the ignition coils. If the ASD relay is faulty, you won't get spark. Check and replace it if necessary.
Throttle Position Sensor (TPS) and Intake Air Temperature (IAT) Sensor: Ensure that these sensors are functioning correctly. They play a crucial role in engine performance.
Check the Key: If everything else checks out, consider the key itself. The chip in the key has a unique identifier code. Some replacement keys may mimic this code, so make sure your key is genuin..
Bus Line and SKIM Module: Verify the PCI bus line between the PCM/data link connector and the SKIM module. If there's an issue with communication, it could prevent the engine from starting

My interior lights on my 1998 grande cherokee jeep wont shut off
This might sound silly but have you checked the switches on the actual light fittings? They usually have three settings. Permanently Off, door controlled or permanently On. If there are no switches on the actual light fitting try pushing the lens itself at each narrow end. Some lenses rock end to end as the switch mechanism.
My 02 jeep liberty dash not working. No tack,speedometer, fuel or engine temperature. Any help please
- Faulty Instrument Cluster: The instrument cluster itself may be defective or damaged. Over time, electronic components can degrade, leading to malfunctions.
- Fuse: Check the fuse box for any blown fuses related to the instrument cluster. A blown fuse could disrupt power to the cluster, causing all the gauges to fail simultaneously.
- Faulty Wiring: There could be a problem with the wiring harness or connectors that supply power and data to the instrument cluster. Loose connections or damaged wires can prevent the cluster from receiving the necessary signals.
- Vehicle Speed Sensor: The vehicle speed sensor (VSS) is responsible for providing speed data to the instrument cluster. If the VSS malfunctions, it can cause the speedometer to stop working, and it may affect other gauges as well.
- Engine Control Module (ECM): The ECM communicates with the instrument cluster to provide data for various gauges. A malfunctioning ECM could disrupt communication and cause all the gauges to fail.
- Grounding Issues: Poor grounding can lead to electrical problems, including instrument cluster malfunctions. Ensure that all ground connections related to the instrument cluster are clean and secure.
Given the complexity of diagnosing electrical issues, it's advisable to have a qualified mechanic or automotive technician inspect your vehicle. They can use diagnostic tools to pinpoint the exact cause of the problem and recommend the necessary repairs. Additionally, if the issue is related to the instrument cluster itself, it may need to be repaired or replaced by a professional.
1987 Jeep dies when temperature hits 180. Then it will start up after its sits for 30 minutes.
First you will need to determine if there is a problem with the electrical system or fuel system. Connect a fuel pressure gauge to the fuel rail to see if you have pressure when the vehicle dies. It it maintains pressure and the vehicle dies, then check to see if there is a spark issue. Fuel issue could be bad/weak fuel pump, bad relay or restriction in fuel delivery system. No spark could be ignition coil, bad computer, bad electrical connection or relay. To check these systems you need special meters and scanners. Best to take to a repair center.
Dashboard gauge needles irratic jumping on / off / fluctuating
Found out that irratic dashboard gauge needles jumping all over the place was due to computer harness connector pins getting a little corrosive / rusty.....
cured problem, over several times / applications by disconnecting harness, and spraying W\D 40 on pins (plugging in and unplugging several times), then wiping off pins and corrosiveness, and giving final light coat of W'D 40 and plugging in harness. Took a couple of times before problem disappeared over time.
2000 Jeep Cherokee Laredo P0455 & P0765 limp mode and dies driving!
4.7L jeep
the p07 code is tranny error.
cutting off all power means , power to rear wheels or DC battery power to some things ,electrical things die?)
on all cars, DC power must be good first or the computers fail or go mad.
P0455 is gas cap loose, ignore it until all else is cured.
unless cap is missing sure.
Shift Solenoid "D" Malfunction. 0755
fix DC power distribution problems first.
bad grounds, bad connectors, alternator weak or dead
fuses blown or loose
loose wire lugs, or connectors.
rusty ground lugs wires.
title ,DIES Driving.
so dies means engine stalls. not tranny slip right.?
if is stalling can you save the stall before it completes the stall
by fast right foot actions
when it stalls tell the helper all other electrical things that die at the event. Radio dead, head lamps and parking lamps dead.
heater or AC cool blower dead?
Seems to me a pure electrical failure so far.
How deactivate alarm on 1999 Grand Jeep Cherokee
I'm assuming this is the factory fitted alarm. This could be more than one possible answer. First check the silly stuff. are all the doors and tailgate closed correctly? A sightly open door switch could trip the alarm system into thinking the vehicle is being stolen. Is the battery on the Jeep fully charged? A low battery charge can cause alarm systems to throw a tantrum as it's not getting the correct signals from the alarm sensors. If the key has a battery in it or it has a separate alarm key fob check the battery in that as well. When you insert the key it is supposed to communicate with the vehicle's immobiliser/alarm system to allow you to start the car. It sounds like this isn't happening.
Are there any 'new' warning lights on the Dash display? These can give clues to where the issue could be. How are you turning the alarm off when this does happen? If these check don't solve the issue there could be an actual fault with the alarm system itself. Remember this is a 24 year old Jeep and Alarm systems do get old and develop faults. You may need to get an alarm specialist to look at it as they will have the specialist tools to test it. Sadly that will cost you money.
