95 grand am, 2.4lt. f/i Cuts out at 4000 rpm`s

my wifes 95 grand am has a problem that i can`t figure out.
wether driving or in park as soon as rpms reach 4000 it cuts out
and then ill have a hard time starting it again. I replaced the fuel pump, fuel filter, fuel pressure regulator, air filter ign. module wires, cap and rotor and also new plugs. I dont want to throw any more money away. any sujjestions will be greatly appreciated.

Well could be a lotta things....

We could roll out the ole dart board, but....

You need to hook up a fuel preesure gage and see what the pressure is when it cuts out.

Yes! or you could keep throwin darts!
I knew you were going to respond with that answer.

What happens if you have a voltage or ground problem back to the pump.



Thats the difference between some who diagnoses a problem and some who Guesses by throwing parts at it (or throwin darts, makes as much sense!)
