the windows working without the key suggests a bad ignition switch, or the power window relay is stuck in the closed (on) position. do other things that should turn off with the key stay on, like the headlights ?
and yeah, I second the emotion, 'new' parts aren't necessarily good parts. only way you can know for sure is to swap the part with a working car, and if THAT car stops working right, and your car now works, you know your part is bad, swap the good one back and get a different replacement.

Help me help me
Well when I remove the relay a d check the terminals,I have instead of just one hot lead I now have two,and as far as the maf sensor goes the original one I replaced did the same thing that this new one is doing so im even more frustrated confused.Now I went ahead and replaced the suppression relay and I was able to start it up it ran for about 30 seconds and then It just stalled ,but I still don't understand why the minute I touch the accelerator it stalls

Was the fuel pump relay checked? You might have enough fuel to start but not to move the throttle. Mine sat for a long time. Starter died while trying to start the car. Everything you have done was done to the car by PO. I tapped the fuel injectors with a tack hammer and she started up fine. Took about 5 minutes and she idles and moves fine. Could be clogged injectors.
Your issue COULD be electrical. In the book I imagine there are some trouble shooting tips to determine if MAF is bad. I just looked at www.RockAuto.com and that MAF ain't cheap either. Did you replace the air filter? Might be too clogged to pull enough air. The you pull the MAF lead and force it to bypass the MAF and pull through filter.
