1990 Chevy Silverado problems starting

  • V8
  • 4WD
  • 44,800 MILES
Truck starts when it wants to, also cuts off in traffic & want start until its ready to. Ive changed fuel filter, was going to change coil but truck gives trouble when cold.I was thinking it may have a wire short to fuel pump but figure I better ask a pro before I take to a shop.
Do you
have the same problem?

Hello -

To better assist you please let me know your model, K1500, 2500 etc and the engine size in liter and the 8th digit of your VIN.

To save time, please go to Auto Zone (AZ) or O'Reilly's (OR) and for FREE they can pull the codes to the car. Most important: Once they check your codes, if they find something and you don't get it fixed and need to get back with us, please make sure you tell us exactly what the code was, number and all. Example, if the code was E0568 O2 Sensor bad. Then make sure you give us all of that. While there for FREE also they can bring their tester out and check your battery and alternator.

Also, we need to figure out if it is electrical or fuel related. Pull a plug wire off of the spark plug and insert something into the end of it and have someone try to start the car and have the metal object really close to a piece of metal on the engine and see if you are getting a good strong popping blue spark. Don't have your hands on any part of the metal! If there is no spark, then it is electrical. If you are getting good spark then you need to get a fuel pressure check on the fuel pump to ensure it is putting out okay.
