I have a 96 ford f150 manual with 2 fuel tanks and everytime i flip the switch to switch from the front tank to the rear tank the truck dies, anyone have any suggestion on what could cause this? Thanks n advance.

I would first check to see if you have power to the rear when switched.If yes,then i would guess you have a fuel delivery module malfunction.

Would a fuel delivery module malfunction cause the check engine light to come on??

The exact same thing happens in my '92 F-250, I was told it is the switch on the dashboard gone bad.

Is there a fuel pump per each tank? If so, maybe the pump in the other tank is dead, so when it switches over to that one, it just can't pump, thus dying.

First-You need a manual.Next you need to check for power to the [FDM] fuel delivery module[fuel pump-sender check valve and associated parts [FDM].Yes you have 2 [FDM] pumps.One in each tank.

Hi ya Mage218, did you ever pinpoint the problem? My 96 auto, straight 6 dual tanks, does the same thing.

THANKS!

sorry didnt check the post till now but no we never figured it out i assume it was the fuel pump but it got traded in for an 07 dodge ram lonestar edition on 20s

That happened to me for one day a few weks ago. I would switch to the front tank, hear a hissing sound, and the truck would die.

Hi my 95 did the same thing. the gauge would switch, but the truck would die. I replaced the fuel pump, and all is well now. Had to remove the bed, but the job wasn't too hard. the toughest part was the bed bolts spinning, but I tack welded the heads, and it went great.
