Dave,
I sent you a PM a couple of days ago with a few points and questions. What generation or year/group is the ECU or computer. Depending on the generation of your donor you may or may not have an issue with pressure going to 0 after key is left on for 5 seconds without a tach signal or engine started.

The complaint is hard starting when cold... right? We need a bunch more info too help nail this one down. Is cold starts the only symptom? Does she puff a little smoke when it does start, is mileage and power down, do you have a miss in ignition at any RPM, what have you tested, any other clues beyond what he said?
