I assume you have a 2.1 WBX? Your van now can't be started but it started
ok before pump swap?

Bentley should show location of relay in index at beginning of the diagrams
but the fuel pump relay is located inside the black box above the ignition
coil. There should be an image in Bentley Digifant section showing which of
the 2 relays is the fuel pump relay. That section should also show how to
bypass the FP relay for testing purposes. There may be specialty relays
that have internal fuses but relays aren't designed to act as fuses.
(unless they fail in which case the circuit to pump would be open). AFAIK,
non of the Vanagon relays are fused internally.

When key turned to ignition on (engine still off), the fuel pump should
prime briefly but then shut off. So, seeing 0 volts at pump with ignition
switch on, engine off, would be correct.
