Question about 1999 Chevrolet Blazer

1 Answer

Motor shuts down

You can be driving down highway and the engine will like run out of power and the engine will die. After about 20 minutes it will start back up and run for awhile. It is like something is getting hot and shutting off and the resets when it cools down. It will also do it just idleing when you give it gas it will die. Once again it will start back up after about 20 minutes.

Thanks in advance

Have you checked/tested the fuel pressure? sounds like a bad pump and or plugged fuel filter, check the pressure, if it is low replace the filter, if that still doesn't help you will need a new fuel pump, it is located in the fuel tank.

    Hello - Yes I have and I have replaced both of them over the weekend. Still the same. I checked the coil and it had a lot of oil where the coil wire plugs in so I replaced it today. Changed the computer (Electronic Fuel Control System) Still the same. What should I do next?

My 1991 ford f150 dies after 20 minutes and wont start again for another 20


Could be a bad coil. Sometimes when a 'bad' coil heats up it will fail to work properly. When it fails and shuts the vehicle off, this gives it time to cool back down and resume proper operation. Does it run at normal highway speed during that 20 minutes? If not then it could be a clogged fuel filter. A clogged fuel filter will let the vehicle run at idle but will starve the engine at higher rpm's.
