1993 Blue Bird Gas 366 TBI

STILL in need help locating the TBI fuel pump relay and fuel pump fuse, no clicking sound when key turned on. Does anyone know where it is located on this model. Also does this model have an Inertia Cut Off Switch? If so where is it located?

can not help with your specific model? sorry.
one of my buses has a main fuse block under the hood. one under the drivers seat and 2 more in the overhead.
the one under the hood powers alot more stuff than it is labled for.
like my fifth circuit for ignition e also is the fuse for the turn signals.
nothing else on can you hear the fuel pump pressurise?
have you pulled the fuel line to the throttle body to see if you have constant pressure with key on?
what have you done that makes you think it is fuel pump fuse related?
checked power to pump?
not trying to be a pain but what has led you to a fuse?
hot wire straight to the fuel pump yet?
broken wires do happen as well as bad connections underneath.
do you still have a mechanical fuel pump or an electric in tank one.
your engine is old enough it could go both.
yes i have seen mechanical fuel pumps run a throttle body.

My 1990 Thomas doesn't have an inertia switch.
The fuel pump relay is in a box under the hood.

I have to believe you more than likely have an in-tank fuel pump.
Have someone lay under the fuel tank to listen for the pump coming on when you turn the key on.

I can hear the pump come on when I'm in the driver seat, but I'm in a short bus!.
