I have a 92 Deville and I am having a troublesome problem with it. Sometimes when I try to crank the car it won't crank. Other times it will crank fine. It seems not to be getting fuel. I have changed the fuel pump, fuel sending unit, the fuel tank and the fuel filter. The only other device I think it may be is the fuel pressure regulator. After I try to crank it and it doesn't crank, I can leave it for a few minutes and come back and it cranks as if nothing is wrong with it. Has anyone else had this problem with their vehicle. Any help will be greatly appreciated.

You say cranks, to me that is the engine turning over, but does it start, or does it turn over and not start?

The engine turns over but does not start. Also, when ever I press the little pin on the fuel rail, there is a little spurt of fuel that comes out. I thought that there was supposed to be constant pressure in the fuel rail at all times.

Ok, you will have to check for spark then check for the injectors spraying fuel during the no start event.

Max:

When you crank your engine, does it turn over rapidly, or lazy-like? Also curing the situation whereby when you crank it, does the engine keep running? normally?
