One day I got in my celebrity to start it, and it was on for about two minutes then shut off. After waiting two or three minutes, I attempted to start it again. It started but only remained on for a couple seconds. From there on it attempts to start but will not turn over. I recently replaced the initator module and the distributor cap, so I would like to think that these are not the cause.

Have you checked the fuel pump and filter? Please state if you have carburetor or fuel injection.

Before blaming the fuel pump, test for fuel pressure at the fuel rail. You will need a pressure gauge attached to the fuel rail. You should have 37-43 psi.

So if it is the fuel rail then that would need replacing? Or is it a component of something else? Would the fuel pump still be excluded all together?

If you have the proper fuel pressure at the fuel rail, then the fuel pump is doing its job. If it maintains that pressure, then the pressure regulator is working properly. Meaning fuel delivery is not the issue. We may have to look at spark problem, then.

After you check the fuel pressure, check and make sure that you have sparks at the plugs.
