in the rear fuse box is fuse # 1 called fuel pump bad ?

with the relay out with the key OFF does one terminal show 12 volts in the fuse box that the fuel pump relay connects into ?

Customer: replied 2 months ago.
Didnt test the volts
Expert:  Gary replied 2 months ago.

see if one terminal does

also put back in the relay and see if that fuse shows 12 volts when cranking it over

99 % of these if NOT getting 12 volts at the grey wire at the fuel pump are bad internal fuse box failures

if the wiring under the box looks good replace the fuse box and be sure to put a new fuel pump relay in it and coat the terminals with alot of dielectric grease that should fix this problem
