It sounds like you have a vacuum leak or intake gaskets leaking. Try this. Start the engine and let it reach the idle it want to go to. Get you a can of Brake Clean and spray it around the intake manifold (it on the top center of the engine, you may have to removed a plastic cover) If the engine idle changes up or down then the intake gaskets are leaking hence your vacuum leak. I hope this will help you.

i would first check the timing and if that does not fit i would take the cover back off and look at the belt for a bad or missing tooth

Wow you have replaced a lot of stuff. Lets go back to the Fuel pump. When you replaced it did you replace the hose between the pump and the sending unit. These are common for splitting. Have you hooked up a fuel pressure gauge to check what pressure you have? It should be real close to 13 psi and should raise to at least 18 or 19 when you pinch off the return line.
