Picking up on Smitty's list of good things to question — has the fuel mixture been checked since new pump and injectors were installed?

How about fuel pressure? The pump is new, but so is your problem, and I wouldn't rule anything out at this point.

Is this hopefully a California car with an O2 sensor? That would be a big help in checking mixture.
