I thought you already changed the crank sensor?

I changed it but I am not certain they work because I picked it from the junk yard.

Well without plugging into the ECU to see some sensor readings your guess is about as good as ours.

Does the Beretta have a cam shaft sensor? If yes where is it located?

Where are the grounds that I should check to make sure there is a good ground on the car?

Checked the injectors and they are good. All of them have a resistance between 12.2 or 12.5. When I first replaced the PCM it had no code but now my new PCM gives me a code 14 but I replaced the coolant sensor and no diffrence what else might be causing the problem?

Check the wiring for a short somewhere, do a continuity check on the wire at the ECU to the wire in the bay. And what ECU/chip are you running? Same chip as before just new ECU housing? or completely swapped?

This only happens when I use the new ECU housing. I have changed the chip and it does the same for both chips but if I put the chips in the old PCM there are no codes. Also when I put the new ECU the fan turn on immediately after start.

Found the Problem :Yahoo!: . It is the damn EGR. I thought it was good because it holds vacuum and there is no carbon build up. For some reason when I accelerate the car the EGR would lift causing it to stall. Thanks to everyone that helped me with the diagnosis.
