I'm having issues with the Walbro 255, I was driving my car up a hill and it just died out on me , I checked the fuel pump unhooked the fuel lines from the pump and turned the key and nothing , I then took the pump out of the car and turned the key and it just kinda clicked. I took the pump completelyout and just for ****s and giggleshooked it up to a battery and it turns fine, so I hooked it all back up and turned the key it ran for a sec and shut down and I still didn't hear the pump kick on after it ran for a sec, I unhooked all the lines again and did the same thing and it did it all over again this file pump only has 400 miles on it. If I unhook the fuel lines from the pump it should keep running correct ? Also why would it run for a little before trying to start it then not come back on ?? Any ideas the fuse is fine all connections are good the car only has 1300 miles so I highly doubt fuel filter ?!?!??
