wont start

truck ran fine went down to canadiantire came out and would not start had it towed home seems like it wasnt getting fuel i got a new fuel filter thinking that mint be it filled it up with fuel got it to run for 30 secs or so then it died i cracked a few lines on the injectors and there getting fuel ive noticed my fuel filter is not keeping its prime if i fill the filter up sometimes i can get it to go.
once the truck dies i took the filter off and theres not much fuel left in it seems like its just running off the fuel i put in the filter both tanks are over half full

forgot to mention a week before this the truck would start to chug like it wanted to die

Sounds like your lift pump died or is dying ....

thanks for the pic i found the pump. seems like its pumping fuel but maybe not enough presser? when i bleed the valve on the filter i get fuel out should i get a nice heavy stream coming out? seems like its splashing out. how far should the fuel be spraying out?

I always change out the bolts to the pump with a set of studs, makes it easier to install. The threads are 3/8-16, about 2" long stud would work. Getting the bolts back in is usually the hardest part of the job. You will have to remove the alternator and vacuum pump to get to the lift pump easier. I would also look at your fuel lines from the tanks to the pump, any small leak there would give the same issues. Especially check the condition of the rubber line between the steel line and lift pump.

What year truck is on? The one in your pic or is it an older truck. Did you fill the fuel filter with fuel before you tried starting it? You may still have air in there until it cranks for a while. If you filled the bowel and you still have no fuel coming up I would believe you either A. have a fuel line problem, hole the line, old dried out hose, or B. the pickup on the tank sending unit is damaged, either the sock or the end may have broken off. You can try an old trick that I used to find a pin hole in a line, take a air nozzle and put into the tank through the fuel cap with a rag wrapped around it and blow into the tank. If you have a leak, it will show up then.
