fuel pump runs out of tank but quits when installed
Are you testing it just by hot wiring or,are are you hooking it to the wire,s at the pump connector?
Most likely a bad pump motor, it will run with no load but when a load is applied it can't pull it. I would recommend getting the entire fuel pump module assembly while your already there.
by hooking it up to the plug for it. the guy i got the truck from said he trouble from the computer before. ive got another one here, wasnt sure what i have to do.
