? On Code 54
Alright, last question (for now....) So if the vehicle sets a code 54 (high/low fuel pump circuit voltage) is that basically telling me the relay is shot? where is that voltage measurement taken - at the pump? What sorts of things do I need to be looking at. Keep in mind my '85 vette still runs and drives, but has seemed to lose just a bit of ***** the past couple of days, and idles a bit rough. Does it sound like a fuel pump gone bad?
I also have the following codes, for reference purposes:
Code 52 - calpack missing or faulty
Code 53 - system voltage too high.
I am sure my alternator isn't overcharging. The vehicle has a hypertech thermomaster chip in it. Any suggestions?

I have seen those codes before, and they have befuddled the hell out of me, too.
They are somehow connected... and I think they are the result of a bad calpack or memcal.
The 85 has such a crude computer... you may want to investigate updating it to the ECU from an 87.
