i have a 2001 chevy 2 door blazer with some fuel related issues. a couple of weeks ago i was driving and the truck died. so i towed it back to the house and picked up some starting fluid. i diagnosed it by getting the engine to run on the starting fluid. so i ordered a whole unit from rock auto and replaced it. i got the car running. the next day the truck died again so i replaced the fuel filter. and it kicks over for a second and than stops. what could possibly be the issue the truck only has 80k on it?
