Chevrolet Repair Questions? Ask a Chevy Mechanic for Answers ASAP
When it wont start,,,have you checked for loss of spark at the spark plugs or loss of fuel pressure? It will be one or the other.
These must be tested at the time it wont start so you know which area to begin testing.
Let me know please.
If the spark is good, then most likely its a bad fuel pump. What happens is after they get hot from running for awhile, they slow down and cant make enough fuel pressure to keep the car running.(its an electric pump inside the gas tank) Its an easy test with a fuel pressure gauge connected to the fuel rail. These fuel pumps are VERY common to fail on these cars and we replace a lot of them.
