Theres only one fuel pump relay, unless you have dual tanks. Be sure you have 55-60 psi fuel pressure. I "think" the oil pressure switch supplies power to the fuel pump after the engine is running.

My 1999 gmc truck with v8 350 moter will only start with starting fluid


It is very common that the fuel pump goes out on these. Try a fuel pressure gauge to check, or have someone put their ear close to the fuel tank when you turn the ignition switch forward (Not cranking) You should hear it cycle on for about 5 seconds

My 1999 GMC Sierra wont start. It has the 5.3l V8


Sounds like a security problem that is preventing starting. It will run for a few seconds and then die.

Where is the oil level sensor located? oil guage wiggles between 40 & 60 at idle and stays on 60 on the road.


That's not oil level you see on the gauge -- that is oil pressure in pounds per square inch (PSI). It is normal for the pressure to fluctuate when the engine RPM goes down. If it stays on 60 PSI on the road, you are very lucky -- that is excellent oil pressure!

My gmc 2000 4x4 5.3 v8 starts than stops immediately


I had that problem and it was a blown fuse in the interior fuse box.  Check the fuel gauge, if it is not working that is what it is.

This deffinently sounds like your ignition module, it is located on the side of the distributor generally hald on by two screws. This is a very common thing with Chevy / GMC. Good luck and remember to rate all the solutions that you get, thanx.
