Re: Fuel Pump Seized on '93 YJ
Right above the "E" brake release handle is the bolt that holds the brake assy
to the dash panel. In '91 they attached the ground wire to that bolt on the
back side with a nut. Most likely that nut is loose and so is the ground wire.
That ground was relocated in '92 I believe. For sure it was by '93.

Re: Fuel Pump Seized on '93 YJ
The seatbelt buzzer masks it. He'll have to buckle his seatbelt before he
turns the key.
I hear my `89 Cherokee's fuel pump every time I start it.

When I got my rig with the radio off and no buzzer sound I would hear
the pump prime when I turned the ignition. Since I had the pump
replaced I hear it prime when the ignition on, but it also hums along
as I drive. I have read that some aftermarket pumps are louder than
stock and this is the norm. Have had the new pump in for 2 months now.
