Hi, I have a 1998 5.7 Vortec Silverado automatic, it will crank ,has spark but no fuel. Last week I drove to Orlando Florida from North Carolina and drove back towing a vehicle. Got all the way home turn the truck off went out to restart the truck did not hear the fuel pump Prime, and vehicle would not start. I replaced the fuel pump relay that did not work. I attempted to put 12 volt positive to the fuel pump feed harness and it just sparked back at me so I stopped, and figured the fuel pump is locked up burnt out. It was making the usual loud whining noise for about 2 months ago. The truck has 351000 miles on it I do not know if the pump has ever been changed. I've had the truck since 2009 and have not replaced it. Any suggestions,? Pump?.
. Thanks in Advance

 

check the ecm fuse first I just had the same issue with mine its a 20 amp mini fuse in the fuse box under the hood

 

From your description it sounds like you need to change the fuel pump.

 

i have heard that the fuel pumps only last to about 125000-150000 if kept cool with at least a quarter tank of fuel to keep it cooled.

if your pump has 315000 then you got your monies worth out of it !!!

Sorry for the late response.. It was the fuel pump, raised the bed and installed a NEW Delphi Fuel pump. Fired rite up..!!!! 353K and running strong again
