I'll try and make this short. Have a 97 Trop. 454 vortec. Sat for about 2 years. I went to take it out again and it started just fine. While I was flushing the water tanks, I let it idle and it ran out of gas. Put 25 gallons in and wouldn't start. Changed the fuel filter 3 times now it will start but when you go to excelerate it stalls out. Fuel pressure is only about 10 psi at the engine, running or not. I disconnected the fuel line from the filter and tried pumping out the fuel so I could drop the tank and no fuel would come out with the key on. Also I know that the fuel line from the tank to the generator has a split in it. Would this be a fuel pump issue or ? Any help would be would be very appreciated.

Fuel pump will only run for approx 15sec after ignition turned on unless the motor starts.

Sorry ' forgot something

sounds like the pump ingested something. Were the filters totally plugged? If so the tank has to be pulled to clean it.

Thanks Skip, The inline filter was not plugged. Question, If I disconnect the fuel line on the tank side of the filter and blew compressed air back to the tank could that possibly clear the debri? There seems to be 4 nuts (2 on each end of the tank) and 2 straps that hold the tank in place, must all of the nuts have to be removed?

IF the tank ran dry, it is even money that the fuel pump sucked up some gook from near the bottom of the tank. Might have to remove to clean it, or even replace it. Before I did that, I would try some low pressure air (20 psi?) on the fuel line back into the tank to see if it busted anything loose. It's a long shot and probably won't work, but any chance to avoid dropping the tank...

In-tank fuel pumps are cooled by the gas they are sitting in. If you ran it out, there is a chance it damaged the pump.

Try the straps first, but I think all the bolts will have to come off. Don't forget the filler and vent hoses, tank may have to be part way down to access those.
