Check the wiring to the pump and check to see if you have a good ground, also check out the fuel pump relay switch under the hood

My fuel pump is not getting any power the fuses are ok

Check the fuel pump relay located in the fuse panel under the hood. Switch it temporarily with the horn relay or the a/c relay. Check for power at the pump. If it starts it's fixed and u now have a horn inop or ur a/c is inop. Change relay is the fix. If no power to relay check wires for corrosion and check continuity. If wires are good and you end up with power at the tank , then the problem might be that u need a fuel pump has great prices . Check em out! Have someone set ebrake and turn the key holding it in the on position. Bang on the tank with a rubber mallet. If it starts u kno it needs a fuel pump.

Have you checked the fuel pump relay yet ?
It should have power for three seconds when you turn the key switch on, then power after the engine starts.

Lost power to the fuel pump going down interstate

1. The fuse for the fuel pump may have blown or the fuel pump Relay may be faulty. If you have not done this already, check the fuse and replace it if it is blown. When replacing the fuse you must use one of the correct amperage. If it requires, for example, a 15 amp fuse, that is what you must use.

If the fuse is OK then replace the Relay for the fuel pump and re-check.

The location of the fuses and relays for the vehicle are shown in your owner's manual.

2. Check the wiring to the fuel pump.

3. On further testing, the fuel pump itself may be faulty and require replacement.

Trying to find the fuel pump FUSE.

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.

I assume the fuel pump fuse is good?
The only time voltage will be sent to the fuel pump will be the first 2 to 3 seconds if the starter is not engaged. You will want to crank the engine over and check for voltage on the load side of the relay, circuit #30 at the relay.
Let me know after you check.
