The electric pump is attached to the fuel sending unit, located in the fuel tank.

REMOVAL & INSTALLATION

  1. Properly relieve the fuel system pressure.
  2. Connect the negative battery cable.
Be sure to keep a Class B (dry chemical) fire extinguisher nearby.

CAUTION Due to the possibility of fire or explosion, never drain or store gasoline in an open container.
  1. Drain the fuel tank, then remove it from the vehicle. Refer to the procedure found later in this section for details.
  2. Using the GM fuel gauge sending unit retaining cam tool No. J-24187, J-36608 (or equivalent) or a brass drift and a hammer, remove the cam locking ring (fuel sending unit) by twisting counterclockwise. With the locking ring released, carefully lift the sending unit from the fuel tank.
  3. Remove the fuel pump from the fuel sending unit, by performing the following procedures:
    1. Pull the fuel pump up into the mounting tube, while pulling outward (away) from the bottom support.
When removing the fuel pump from the sending unit, be careful not to damage the rubber insulator and the strainer.
    1. When the pump assembly is clear of the bottom support, pull it out of the rubber connector.
To install:
  1. Inspect the fuel pump hose and bottom sound insulator for signs of deterioration, then replace, as necessary.
  2. Push the fuel pump onto the sending tube.
  3. Using a new sending unit-to-fuel tank O-ring, carefully lower the sending unit/fuel pump assembly into the fuel tank.
When installing the sending unit, be careful not to fold or twist the fuel strainer or it may restrict the fuel flow.
  1. Secure the sending unit by turning or driving the lockring clockwise and into position under the tabs.
  2. Install the fuel tank assembly to the vehicle.
  3. Connect the negative battery cable and check for proper pump operation.

Hope this helps (/remember to rate and comment this).

You must replace the sending unit in the gas tank to correct this problem, or do you already know this?

SOURCE: where is the oil sending unit located on a Chevy S10 Pickup.

I would not dismiss the possibility of the oil pressure switch being in the pump circuit...gm has used these on and off since the chevy vega. (remember them?)

SOURCE: 1998 chevy pickup won't start. Replaced fuel pump

How many miles are on the engine? Has the timing chain ever been replaced, if it hasn't there is a possibility that the timing chain has jumped a tooth on the cam gear which throws off the ignition timing and will keep it from starting but you will still have spark and fuel.

Check to see if there is any power getting to the fuel pump, if there is 12 volts going to the fuel pump then replace the pump, if there is no voltage present, the problem could be the fuel pump relay, a fuse, or a break in the wiring.
