The instrument panel is loosing its connection to the PCM. Generally caused by loose connectors or dirty pins. Most common location is the under hood breaker box. disconnect + battery terminal...1) Remove box and clean the large screw that connects to contact under box. it gets dirty and grease builds up...2) using ohm meter set on lowest scale measure from - battery to both chassis and engine block...must read less than 50 ohms...if you read 2500 ohms (Example) there is a bad ground from battery to fender, firewall and engine block...You can purchase ground straps...Install straps from - battery terminal to both frame and block...3) check for frayed wiring harness from steering column by emergency break...4) Disconnect all connectors to PCM and clean contacts with DeOxit (radio shack carries this product) ...These are the common faults...If this list does not yield a fix let me know...saailer

2003 grand Cherokee cranks over and will not start. Changed the cps already. The fuel gauge reads empty, empty light comes on and circle with key and line threw it is on dash board. When it does start...


You will have to check each connector on the PCM for moisture and the wires for shaving. Fuel quantity info comes from the PCM via the PCI data bus. Moisture in one of the connectors could short the data bus out and the engine will not start and indicators go to zero.

My 96 jeep cherokee will start for a couple sec. then shut down my cehck engine light do not come on or none of my gauges can anyone help me


The flashing light on your car is telling there is a problem. On some vehicles require a OBD2 code scanner for the diagnosis. Once you know the code, you can most likely repair it yourself. There are fairly easy procedures that most people are capable of repairing.

Dash lights work but no gauges in my 1994 dodge intrepid!! i have checked every fuse i can find in the dash and under the hood but they still won't work, they don't even flicker when i turn my key....


If you have a 1993-1995 Intrepid and you have a check engine light, you can find out what the codes are by following this process:
To obtain fault codes using the MIL (Check Engine Light):

1. Cycle ignition key to ON, OFF, ON, OFF, ON within 5 second (do not actually crank engine!!)

2. Count the number of times the MIL on the instrument panel flashes on and off. The number of flashes represents the trouble code. There is a slight pause between the flashes representing the first and second digits of the code. Longer pauses seperate the individual two digit trouble code.

Example:
Lamp flashes 4 times, pauses, then flashes 6 more times. This is an indicates a DTC of 46.

3. Lamp will always flash 55 at the end of the test. This signals the end of the test.

You have put the computer in diagnostic mode and it will now display any codes that have been stored in memory. Each code will refer to a symptom your car is feeling.

Here is a list of all codes that can be displayed and what they mean:

Post Back With A Code, If you get one.
I Hope this Helps,

After reading through the Article, Pop the Hood and Check out the Grounding Locations. Look for any wire that looks like it should go somewhere. Screw it down (Ground) to the Frame Rail.
First Disconnect the Negative from Battery For a couple Minutes,
If the Engine was replaced they mighta missed a couple Grounds.
One is front Driver corner by the Battery
Two is on Passenger Corner.

Check engine light on after all dash light lit up


I don't know why , but you can reset the check engine light by disconnecting the postive battery cable only and wait 10 - 15 minutes and then reconnect this will rest your light, if there is a real problem the light will come back on, otherwise it was just a minor emission problem and correct itself.

it is not the plugs.if you remove the printed circuit board,which is double sided,you will see that the solder joints on the back of the plugs where they are soldered have cracks in them.resolder the plugs.

Dash gauges not working


Check the large multi-pin connector in the electronics bay in the engine compartment. The bay is a fairly large black plastic box on the driver's side. Open it and disconnect the largest connector inside (one screw). Spray electrical contact cleaner on the pins and re-mate the connector. This worked on my '99 with the exact same problem. You can find other examples of this with a Google search. It may not solve your problem (could also be a wiring harness problem), but it is incredibly simple and worth a shot.
