Ways to tell if you have a bad FPCU?

[Riverhawk44]

I had the fuel pump and FPCU replaced on my 1995 Q45t. One or the other or both are bad (because my cars runs great now). Before I had them replaced I didn't have WOT (only 15psi) but my cruise control and idle were great.

Anyways I opened up the original FPCU unit just to look inside and it looks spotless. So I wanted to see if you guys knew a way to check to see if its still good or not? I had it replaced because it was my understanding if you're replacing a FP, you should get a new FPCU just to be on the safe side.

And again I wouldn't have been able to make the repairs to my car if it wasn't for all you guys and this forum. Thanks to everybody who contributes.

temporarily swap your old pump controller with your new one- you will know real fast!!!!
