UMM, Try starting with something simple. Like a clogged fuel filter, or bad plugs. Sounds like your over due for a new fuel filter.

Try cranking and watching the oil psi gage. If it cranks and cranks and nothing happens until the oil psi goes up, it may be your fuel pump relay, as someone mentioned earlier. Mine went too. You could override the relay and see if it cranks, then you will know.

fuel pump relay could be out. it wouldnt activate the pump until sufficient oil pressure was reached (cranking over). the pump will only work off the oil pressure sensor, it uses the relay for start up.

My vote goes with this one. I had a simular problem turned out to be the fuel pump relay. When you turn the key in the on position do you hear the fuel pump turn on?
