1997 chevy silverado 1500 350 vortech, new fule pump not working

it just a basic tools. find the filter and see what size it is.
crawl under the truck on the driver's side, follow the fuel line from the fuel tank to the filter(shape:cylindrical).
make sure the line has no pressure. you should pull the fuse for the "fuel pump" relay, then start the engine and allow it to stall.

disconnect battery, disconnect fuse pump fuse, locate fuel rail where the fuel injectors are connected to, then unmount the fuel rail, then disconnect wire to injector, then wiggle it out of the rail, then do the same for the other injectors. to install simply follow reverse order.

ck wires go to starter make shur there is no broke wires or wires leaf off of starter

2 possible problems the easiest is an inline fuel filter on the frame rail below the drivers seat. Second the mapping sensor may be shot it monitors several fuel and ignition functions.

Sounds like it. On new automobiles the fuel pump is in the gas tank, cools the pump, but you can disconnect the pump and put on an outside pump instead of pulling the gas tank and replacing gas pump and tank. Leave old pump in gas tank.

Check your fuel pump they usually go out after 10 yrs or so. Also check your fuel filter. Both easy fixes.

Good Luck!

try the multiplug connection on top of the tank

Hi I have a 4x4 2003 chevy 3500 silverado dually with dual tanks
rear tank stoped pumping into front tank and was full . I siphoned the fuel out of rear tank and fuel gauge reads 9/16 full . is there a way to reset the fuel sending units so they can calculate the fuel readings. I always filled the two tanks with the same amount of fuel
until now ? I'm thinking there is a inkine fuel pump

a faulty oil pressure switch will do this

The problem may be that it has 55 psi instead of 60-65. Could be the fuel pressure regulator or the fuel pump itself. I have read that these engines need 60 psi minimum to start reliably. Also with the engine off, look down the throttle body with a flashlight and see if the intake appears wet inside, indicating leaking central injectors. There is an upgraded injector assembly available with pressure regulator at autoparts stores. Requires 4-5 hours to replace with experienced mechanical skill level. Would definately upgrade if the pressure regulator needs replaced anyway.
