My 1996 K1500 5.7liter just had fuel pump replaced, runs fine until you let it idle for 10 minutes with AC on. Then the truck dies immediately and restrats and runs fine after sitting for 20 minutes. No check engine lights come and engine is not overheating.

- The truck stopped running totally. I had it towed to a service station. They said the fuel pump was bad and they replaced it. The truck started and ran fine after the new fuel pump was installed. My current problem with the truck shutting down after 10-15 of idle began after the fuel pump was installed. I took the truck back to the service station, they checked the computer and there are no error codes. They told me it could be the crank sensor which I replaced but it did not solve the problem.

Clarification Request

Did it do this BEFORE you changed the fuel pump? Why did you change the fuel pump?
