    I had the same, my truck started cutting out on gravel road then eventually shutdown. had dash board light but no power to starter or fuel pump. A mechanic in a construction camp looked at it and found that the computor lost ground. used a jump wire to ground computor and drove truck to shop. DHarris

My 2002 Chevrolet Silverado 2500 HD Diesel instrument panel went completely out and would not accelerate.


check your timing chain its probably broken. diesels have no spark plugs and uses compression ignition and uses a lot of battery charge to turn it over. thats why it sounded like it was dead. if the chain brakes the upper and lower cam and crank shafts aren't in time together so you get no compression ignition. sorry for your troubles and hope i helped

  • 1 Put the vehicle in park, and turn the ignition to "On/Run" (don't crank the engine).

  • 2 Press the odometer trip stem on your instrument panel until it displays the message "Relearn Remote Key." Then release the stem.
  • 3 Press and hold the odometer trip stem again for three seconds. You will see the message "Remote Key Learning Active."

  • 4 Press both "Lock" and "Unlock" on your key fob at the same time, and hold the buttons down until a chime sounds. This should take about 15 seconds.
  • 5 Repeat Step 4 for each additional key fob you wish to program.
  • 6 Turn the ignition to "Lock/Off."

    2003 GMC Intermittent Starting Problem


    Check the other end of battery cables, may have good connection at battery but not at starter or ground. (Always check ground first, often a source of problems.)

    Next time it happens, try hooking up jumper cables and see if the intrument panel lights up.

    Also, check for loose fuse, not properly seated fuse. And cables to fuse block. (That model may have more than one fuse block)
