I'm having some problems w/ my '82 ht4100 deville. The first problem is that the fuel pump connector doesn't receive power when in the "on"position for that short time or when cranking or car is on. I put in a new fuel pump (old one was bad) and fuel filter. By bypassing the connector everything works and the car starts.
The connector was working and then quit suddenly. Could this be a relay that went bad? If so, do you guys know which one it is? (They don't seem to be labeled)
Also, when the car is on, by bypassing the fuel pump connector, I get a steady check engine light. I saw to receive codes you hold "off" and "warmer" but I'm not getting anything. (My warmer button might be on it's way out) Is there another way to get the codes? I know with my '84 chevy I can short the connector and get the codes to display via blinks of the check engine light. Does this car have something similar to that?
