2004 Chevy Tahoe Four Wheel Drive Automatic 99000 miles

My car will not catch as I try to crank. It's not the battery so what could it be?I was told that it might be the fuel pump or the starter. Is there anything that would indicate that?
Thank you

Do you
have the same problem?

Ok, I take it when you say it won't catch you are saying that the engine turns over, just won't start.

If so then you can rule out the starter also.

Now, then turn the key to the on position without trying to start it. Make sure everything esle is off. Listen for a humming noise, it will only last about 3 - 5 seconds. If you don't hear anything then it could be the pump or a relay.

The pump is located in the tank.

The relay is located if the under hood fuse block.

To check relay look at number on it the look at relays around it and see if any match up if so just swap the 2 and see what happens. Just make sure you remember which one tou swapped so if it starts you know which relay you need to replace.
