So been having problems with the fuel shut off solenoid i changed it out yesterday thinking it was bad whats going on is i have to get out of my truck push the lever up manually to get it to lock in place in order to start my truck but when i run the truck for awhile then i have to get someone to hold it up till it locks in place and keep holding it until i start it and let it run for a second if not it will just fall back down stuck on what to do daily driver so need help asap please

 

There's a two big relays just above the engine, next to a brake booster. One is for fuel heater and the other one is for fuel solenoid. Swap them around and see what happens.

 

That did not work any other suggestions??

 

the truck will still start if i push it up manually without those
