Need a diagram of fuel pump fuses and relays - 2000 Oldsmobile Silhouette

The fuel pump relay is under the hood right next to the fuel pump fuse, both are clearly marked. The under-hood fuse and relay center is on the drivers side it is a large black plastic box. I think you will find that you need a new pump and a new fuel pump connector at the fuel tank. Have a trained technician confirm this before replacing any parts, the fuel pump is very expensive.

The fuel pump relay is on the driver's side in front of the tire. You have to remove the bumper to get to it. Easily replaced once the bumper is off. Two minutes at the most. It's the one not in a row.

The primary (coils) side of the fuel pump relay is powered by the CRANK fuse (10 Amp) located in the instrument panel fuse block. This fuse is hot ONLY when the ignition switch is in the CRANK position. The secondary (contact) side of the relay is powered by the ECM-B fuse (20 Amp) which is hot at all times. This fuse is located in the engine compartment fuse block. The electric fuel pump in the tank only operates during engine cranking.

The fuel pump assembly consists of fuel pump relay,fuel sensor,the fuel pump controlling fuse,its ECM B fuse. The fuel pump and oil pressure switch. ----------- For its wiring diagram, click the link below and refer the diagram:--- http://technoanswers.blogspot.com/2011/10/fuel-pump-wiring-diagram-for-1998-chevy.html ----------- This should help.Thanks.Helpmech.

Check the fuse but there is a good chance your fuel pump needs to be replaced. If the fuse is good check for power to the pump first then you will know you need a pump

There is no fuse specifically dedicated to the fuel pump on this year and model of Suburban. This Suburban is equipped with dual tanks and as such has two relay switches, primary and secondary, both of which are located at the main fuse box in the engine bay, that power up the respective fuel pumps.

The closest fuse (15A) controlling either of these relays also powers up the main control module (located beside and below the main fuse box). So, if one needs to disconnect the fuel pumps from functioning, then the only effective method is to disconnect the fuel pump relays.

There is both a fuse and a relay for the fuel pumps electrical system. The image below of the Power Distribution Box is located in the engine compartment.

Your problem can also be with the Bosch ECU, these are prone to failing and also control the fuel pump, they can however be rebuilt.
