How long since a tune-up? Any applicable trouble codes? If you have that spider fuel system, that system is noted for problems. Check the fuel pressure, key on engine off, 60--66 psi. After it starts it will run with less pressure. In the past I have seen service bulletins about the poppet valves sticking, the fix was a cleaning procedure, that was a shop procedure.
Mainly the bulletin talked about hard starts in the morning because of poppet valves sticking, after it starts it will usually run fine the rest of the day, after it sits overnight, you have the same problem the next morning.
There could be other issues?
If it cranks good but won't start, have a helper crank it while you visually check for spark at the spark plugs. If spark everywhere, use a gage and check proper fuel pressure and fuel injector pulse.

Make sure that your fuel presure is up to at least 60 psi if not that could be your problem. If not, make sure you are getting spark, if not could be your Crank sensor or ingniton module ECM. Usually if your Engine control module wouldn't be bad because of your fuel pump is working, but may not be putting out the proper pressure for the fuel system. Fuel Pumps are a Problem with that year..

Hi there. If the fuel gauge is the only one acting up, its probably a loose or corroded wire on top of the gas tank where the fuel pump sets in. It could also be a loose wire on the back of the gauge, which is easier to get to so you could always check that first by popping off the dash pannel and pulling out the instrument cluster and looking for a broke wire on the back of the fuel gauge. But if I had to bet I would guess its on the other end by the fuel pump. Worse case sinario, maybe a bad sending unit.

I also agree it sounds like a fuel pump issue. Its easiest to remove the box (6 bolts {need impact wrench} disconnect wires at plugs and disconnect gas filler hose) and lift box up. A hoist is easiest but 6 people can lift it easily. The fuel pump can easily then be replaced. Takes about 1 1/2 hrs. to do entire job this way and its so much easier!
Good Luck!

SOUND LIKE INOPERATIVE GLOW PLUGS. THE GLOW PLUG RELAY OR CONTROLLER COULD BE THE PROBLEM.LET DEALERSHIP FIX IT.YOU NEED CERTAIN TOOLS TO WORK ON DIESEL ENGINES.
