Truck Won't Start/Fuel

1983 302 2150 Mechanical Fuel Pump

Truck won't start. Looked in carb, no fuel squirting when pedal pressed. Will start when gas in poured in carb and will run for 2-3 seconds. At this point I can get 2 weak streams of gas in carb then nothing. Have to pour gas back in carb and will run for 2-3 seconds...
Has my fuel pump died?
Fuel filter? (1 year old)
Truck ran fine yesterday.
Thanks

Are you sure there is fuel in the tank?

Yup!

I might be able to help with this.  Had a similar issue this spring.

1. How long has it been since you changed your fuel filter?
2. Do you run the tanks down where you suck the crud off the bottom?
3. Check for old fuel lines with wear, tear or cracking.  (Mine are 99% rubber hose from previous owner)  

In the end, I would've bet my children that it wasn't the fuel filter because I changed it about 6 months earlier.  But lo and behold!  It was.  Since swapping filter and hose to the pump, I've had ZERO issues with fuel getting to the engine and running.

I don't know the 302 so I ask the question to someone else if it's a mechanical pump like my 351.  The old mechanical pumps are pretty reliable from what I've read and been told.

Seals and keeping oil in the truck are another story completely for me...  

Turns out the issue was the rubber hose between the gas tank and hard fuel line.

Sucking air...

Glad you got it fixed!  

The rubber hoses on these trucks don't like ethanol and I've seen them leak air when the engine was running and ooze gas when the engine was off - right through the sidewall with no apparent holes in them.
