Fuel tank/replacing fuel pump

There is only one way to remove it. However, I would recommend having as little fuel in it as possible and use a jack to lower it. Protect the tank from the jack by using wood between the two.
1. Relieve the fuel system pressure. Refer to the Fuel Pressure Relief Procedure.
2. Raise the vehicle. Refer to Lifting and Jacking the Vehicle.
3. Drain the fuel tank. Refer to Fuel Tank Draining Procedure (Utility Single Tank) or Fuel Tank Draining Procedure (Utility Dual Tank Front) or Fuel Tank Draining Procedure (Utility Dual Tank Rear).
4. Remove the evaporative emission (EVAP) canister.
5. Disconnect the chassis fuel pipes (2) at the fuel tank pipes (1).
6. Cap the fuel and EVAP pipes in order to prevent possible fuel system contamination.
7. Disconnect the EVAP vent pipe at the fuel tank clip (5).
8. Loosen the vent hose and filler hose clamp (4, 2).
9. Disconnect the vent hose and filler hose from the pipe.
10. With the aid of an assistant, support the fuel tank.

NOTE: Refer to Damage to Fuel Tank Straps Notice in Service Precautions.

11. Remove the fuel tank strap attaching bolts.
12. Remove the fuel tank straps.
13. Carefully lower the rear of the fuel tank slightly.
14. Remove the fuel sender cover on the Suburban only.
15. Disconnect the fuel sender and the fuel pressure sensor electrical connectors.
16. Remove the fuel tank.
17. Place the fuel tank in a suitable work area.
18. Remove the fuel feed and return pipes (3) from the fuel sender and the retaining clips.
19. Remove the fuel sender assembly from the fuel tank.
20. Remove the EVAP pipe from the fuel tank roll over valves (2, 4) and the retaining clips (1).
21. Remove the fuel fill hose and the vent hose from the fuel tank.

See diagrams below

Do you hear pump run for a few seconds (prime)when key is turned to on? Have you checked for spark/

State the question better. Pl if its turning over and wont start. Remove the duct at the intake manifold. Pour fuel in intake. Does it start? Then come back.

Youll need to do what we said!

Use plug hole b and c they are marked on the connector. The blue and black are for the sending unit. Pic included

Sounds like possible pump gone bad. Test fuel pressure and watch it when it quits.

What I sent is thfor the proper year car you asked for. If it's different then it's the wrong year posted and the blue wires will be either light or dark blue or possibly green which all of those colors are posted in the diagram I sent.

The diagram I sent is correct for that model year. Are you sure it's a 2005? If the pump didn't com eon tha tis completely different from wha tyou first described. Have you check yoru relay an dfuse under hood? Your oil pressure switch and is the pcm tellin g the relay to workk? Check all that first before you just decide it' a fuel pump problem then take everything apart and don't know how to put it back togehter

You need a pro model scan tool to fix this. The voltage is high going to the fuel sender and the scan toold needs to do some stuff you can't to fix it.
