CAR WON'T START INTERMITENTALY

1990 Oldsmobile 98 • 170,000 miles

I have a Olds 98 with 170,000 miles on it. The car start and runs good with no warning lights or that type of thing. But twice now when I have gone to start it the car will turn over fine but will not start. Both times this has happen at night. When I have gone out the next morning to see what is wrong with the car it starts and run fine. It has not start twice now with about three weeks in between. What should I be looking for that could be causing this problem?

Fuel injector or ignition relay failure. No fuel pressure when the problem occurs. No spark when the problem occurs.

You don't. You check them when the problem occurs. Use a test light to check for injectors being pulsed. Use a screwdriver in the plug wire to check for spark. A fuel pressure gauge is needed to check fuel pressure.
