Fuel pressure is 0. I attached a plastic line to the test port, push in the needle valve and get no flow when cranking engine. I disconnected the fuel line before the fuel filter and get no flow after cycling the ignition 5-6 times. You can hear the fuel pump run for 3 sec when cycling ignition which results in a "dribble" of gas.
Dropped the tank, pulled the pump & tested it in a bucket of water. It runs, pumps water and appears to have good pressure (did not measure).? Dried it off and reinstalled it. I now have fuel flow at the filter (didn't have that before) - reconnected the fuel line and the truck starts & runs fine. I did notice some fine black particles pumped out with the gas when testing the pump right after I reinstalled it.
What now? Is it fixed, Was it just clogged, will it die again as soon as I hang the tank back up and bolt everything down. Intermittent problems are always the worst, you are never sure if it is fixed or just started to work again for a while. What now?
