Message	I've been chasing an issue with my fuel pump not priming on my '93 TT, and I just replaced it with a Deatschwerks DW300, but I'm still getting the same issue with it not turning on with the key on. The car cranks, but no fuel is being delivered, and the lines are dry. I've checked the relay, and it clicks twice at key on. Tried swapping it out for two other relays and it works the same. I've tried bypassing the FPECU per the CZP wiki instructions, but it made no difference. I've confirmed continuity between the fuel pump harness and the bulkhead connectors on the top hat, and I back probed the connecter to see it's getting battery voltage at key on. The only thing different I've seen is that the new pump shows continuity between power and ground with a 50ohm resistance that the old pump did not - per the FSM this is the correct spec. For added context, this car has been undergoing restoration for the last two years and everything has been removed outside of the engine bay and steadily put back in. Not every connector is hooked up currently, so it's entirely possible there's a gap in the circuit I'm blind to at the moment. Anyone have any ideas of what my issue could be? I appreciate any help and insight. Thanks!
