Won't start.

He told me the filter is getting fuel and it shot out the pressure valve on the side at the top. Not sure which pump is getting fuel from the tank to the filter assembly.

Ok... What should I test next? I am hoping it is electrical at this point.
Open the hood. have some one crank the engine over, loosen up #1, 3, 4 @ the injector untill u get fuel out of it, then tighten down. open and close them one at a time. Your fuel filter still has air in it as well as the HP pump. Once the air is removed it will run. Should you get NO FUEL out the HP fuel lines, but are able to get it up to the fuel filter by bleeding the filter housing, then the HP pump is bad. I hope someone has already gave you this info.
Good Luck.

Post#39 He has truck running after bleeding system and I believe is all set and one Happy truck owner..

 

But he still don't know if the fuel sending unit is reading right.

My truck will be empty at 1/4 tank. It was working perfect up to the point it quit working perfectly. My bet is his is messed up also.

 

The senders go out pretty regularly, unfortunately.

Filling with a high speed pump will doom them, as they are situated right at the end of the fill port. This blasts the float and skinny float arm with a rush of fuel and loosens the contacting point on the units rheostat.

 

SIXSLUG, the local filling station I go to has 2 nozzles - big boy nozzle for the semi's and little kid nozzle for the rest of us. When I first got my truck someone told me the same thing you did above so I always resist temptation to use the big boy nozzle. It isn't worth the 5 or 10 seconds I might save.

 

Thats very interesting..... Never heard of that before. I have heard though that running biofuels can or will cause issues with the senders because biofuels are more caustic than regular diesel.
