Okay I have the car listed above that I got from my dad. I drove it up here where I live and started cutting out and driving really bad, like it was going to shut off. So, I changed the fuel pump, fuel filter and then it helped a little bit, but now I can start it and I can drive it when it warms up when I turn it off it won't start have to wait for 30-45 minutes to an hour just to start it.

Hi,

It sounds like the crankshaft position sensor is bad. Take a look through this link and let me know if it seems to mirror what you experience:

If it does, when it won't start, see if you lost spark to the plugs. Here is a link that explains how to do it:

Let me know what you find.

Take care,

Joe
