Well, because of the dill holes at the mechanic shop, I am still faced with a problem at startup. It is running way high fuel pressure and you can smell it baaaad... after I let it warm up, it idles high, but fuel pressure is right where it is supposed to be. If I do not let it warm up for very long... all I do is touch the gas pedal and the engine floods itself out and it dies... any ideas what sensor would be telling my computer to pump that much gas??? Thanks.

 

What did the mechanics do when they worked on it?

 

You need to find out why the fuel pressure is changing. Fuel pressure has nothing to do with the PCM or any sensor. Its controlled by the FPR and an FMU if you are running one.
