After cranked and running, the engine sometimes will just quit. This often is caused by depressing the brake or switching on the lights. At first I thought it to be a fuel problem but I changed the filter, checked for water, and checked the fuel pressure. All were fine. Thinking it may be electrical, I took the alternator and had it checked, it was fine. After it quits, it can be cranked back up but acts as though it has flooded and runs rough. The system is not kicking a code or at least the check engine light has never lit up. Not fully understanding later ignition systems(96 model, I am old) and knowing the expense of replacing these parts, I need advice.

THANKS

Hi:
Is the security light flashing when it dies? Also, the incident with the lights may be a short in the steering column. Does the truck have an air bag? Finally, even though the check engine light isn't on, there may be a code stored. I recommend going to a nationally recognized parts store and having the computer scanned for codes. Normally there is no charge for the service, and it may point us in the right direction.

Let me know what you find.

Joe
