most commonly the evap systems vent solenoid is plugged or inoperable causing pressure to build in the fuel tank as you fill up. this high pressure triggers the gas pump nozzle to shut off as it would if the tank had been filled. replace canister vent
Check the pressure to the fuel rail then check it at the line before the fuel pressure regulator, it should be between 55 and 80 psi at the rail and 100 psi before the regulator, if you don't have pressure before the regulator then you have a fuel pump issue, if the rail pressure is low then you may need to replace the regulator.
The issue may be the the in tank fuel gauge float. Over time these can corrode and/or get gummed up which would cause it to get stuck. Another issue maybe the wires running from the in-tank pump to the gauge cluster, if one of the wires has become loose or broken, this would cause the issue as well.
hi it can either be two things, 1st being the fuel gauge itself in the dash it maybe sticking or need recalibrated, and second it maybe the sender itself which it located on the fuelpump in the tank
Hi they do have a two sump fuel tank as they have the rear driveshaft running through the middle of the fuel tank so they use a transfere pump to pump fuel from one sump to the main one with the pick up tube so he is right in a way, however the only problem that would cause this is the transfer pump and it would do it all the time if that were the case id would think the prob maybe the main fuel pump itself maybe having a loose wire
Make sure you have spark first. The fuel in the filter helps, but might be clogged enough to not get enough pressure to start. Running low on fuel tends to allow the junk in the tank to get into the filter. Hope this helps and have a great day.
i have had this problem before these trucks are famous for the fuel gauges not to work in the back of the dash panel there is a nine volt battery that runs power to it and might be dead
