buzzing in the fuse box and blowing fuses

[whitneycas]

I have a 94 sidekick, all of a sudden a buzzing sound coming from the fuse box area. shut off engine then tried to start. cranked over but wouldn't start. Fuel pump fuse keeps blowing. Checked the relays, fuel pump & sender, alternater, battery, computer. Any ideas what to check next

give full spec on car.
1994 what ?

2 door or 4 door
JX or JLX ( jlx has lots of more things that can short out L= luxury)
16v engine or 8 valve.
4wd or 2


no matter , you will have to start pulling items and leave them out and find what left out
keeps fuse from popping.

with a full spec we can get an accurate schematic and point in the correct direction.

It is a 94 sidekick jlx, 4x4, 4 door, 16 valve, standard transmission. Not sure what else you might need to know. My son is a mechanic too and he started with the simple things and moved on to dropping the fuel tank. Has now checked it and the sender and both are good.
Thanks

SEE 94 MPI SCHEMATIC.

this should put you and the correct path.

ECU pulls in , fuel pump relay.

make sure this relay is energized and not bad.

this relay is below ECU , you can see wire colors.

one can hot wire the relay and run the pump from this location, no pull tank.

could be wires, the relay, the pump.


i think? you are blowing the fuse with the black /white wire.
this line runs many things, not just the fuel pump.
FP draws about 5 amps normal.

merry christmas.
