She was running fine, went to start her up and it will rotate but not start!
I have listened for fuel pump and do not hear it coming on when I turn keys to on position. It's a pain to change the pump, so I would like to check out any and everything else related to this problem before having to get down with her and change the pump.
Do you
have the same problem?

Hello,

You can have an operative fuel pump due to a bad pump, faulty relay or wiring.

First you want to check the fuel pump relay.
That relay is located under the hood in the power distribution fuse block (see diagrams below).
First look for obvious faults like bunt pin or burn connector.
You can also test the relay, here is a guide on how to test relays:

You need to also check to see if you are getting power to the relay. In case there is a short in the wire to the fuse block.

Let me know what you find.

Thank you.

I'm sorry, I should have said in question I have checked that relay already. I have checked that relay as well as checked #1 plug for spark.
I have ignition and air just missing fuel. I'm almost certain it's the pump. Just really didn't want to drop the tank. And was hoping I maybe missed something so I wouldn't have to.
Is there any way to change out the pump without doing the tank?

Got it.

Unfortunately, you will have to drop the tank to get to the pump. I am not aware of any other trick that can do in a truck, like removing the bed etc.

However, it is always a good idea to check for power to the pump by checking the harness that connects to the pump.

Actually just saw a video where they made a access plate right above it so it could be removed from up top. So even though I already dropped the tank I'm going to make a access hole!
