SOURCE: FUEL PUMP FOR CHEVY SILVERADO
fuel filter? how about power to the fuel pump,loose ground wire to chasis? wiring harness? terminals clean at point of connection?did you check the fuel pump relay? Relay is located in electrical center under the hood on the driver side.relay and fuse legend will be on bottom side of cover, you sould be able to switch with another relay that you know works, ie: switch horn relay with fuel pump relay, honk horn to insure both relays are working when either relay is inserted into horn slot. Do you by chance have the electrical schematic drawing for the fuel pump?

yes you have to drop the tank. you will also need a fuel line tool to unhook the fuel lines. before you drop the tank see if tou can reach and wiggle the electrical connection on the top of the tank. these pumps have a pigtail issue. please rate

before you drop tank again, check fuses & relay.then disconnect fuel line @ filter turn key to on position should hear fuel pump run and get gas stream out of line. if no flow from line new pump faulty be sure & remove negative battery cable first good luck.

i had the same problem, and it turned out the coil pack was moulding inside wich stopped the spark all together, i ended up changing my coil pack and putting on new wires because the ends connected to the coil were very corroded and that cures the not running part just fine
enjoy

DROP THE FUEL TANK MAKE SURE YOU GO ABOUT HALF WAY THEN UNHOOK ALL THE LINES AND TERMINALS SO AS TO NOT DAMAGE THEM ALSO YOU NEED TO RELEASE THE FUEL PRESSURE AT FUEL RAIL BEFORE REMOVING ANY LINES
