1994 Q45 Fuel Problem
FPCU blown up and we replace fuel pump and fpcu but no fuel coming out. We try another fuel pump that works still nothing. No fuel coming out at all. We check the fuse, it looks ok. What do we need to do? Please help.

Make sure +12 from battery is passing thru fuse to fuel pump relay and then to fuel pump. Follow schematics in FSM.

Using all new parts including the O ring helps immeasurably.
Presume you replaced FP fuse, fuel filter and gas cap?
