Default Died in the middle of the road

Driving from work, stopped in traffic, moved 2 feet and the truck died. I had enough momentum to pull over to the side of the road and a good samaritan helped push the truck into a parking lot.

It's cranking over but wont start. My fuel gage works sometimes but i time it by miles. I estimate i have 1/4 of a tank still (plus added 2 extra gal from a gas can as it was last years gas i use for the lawnmower). Truck has been running fine with no early warning signs. Well it's been ticking but i read (here) that's from the broken exhaust bolt and not lifters and was in the process of getting that taken care of soon.

I'm thinking maybe it's my fuel pump. Any other suggestions on what it could be? I'll be picking it up in a few hours and towing it back to the house.

First you will have to determine if it's a fuel or a spark issue. Do you hear the fuel pump when you turn the key on? Also have a friend crank it and check for spark. If you don't have spark check the ignition coil. If there is power to the coil then the coil is probably bad. Use a test light to check for injector pulse.

Try banging on the gas tank with a hammer. If it is the pump it might revive it temporarily.

Alabama, I tried your low tech solution and it did not work. So I towed the truck back to the house. Will have to try SBJ solution. Stay tuned.

Check/replace your fuel filter. Pull the fuel line from the throttle body (poke it into a bottle or something) and try to crank it over. If gas sprays out your pump is probably alright and it'd be time to check the distributor or coil.

Fuel or spark problem...that's always the question.

Usual tests:

Switch on key and listen for the fuel pump. Does it whirrr for a couple of seconds and then stop? Probably not the pump then.

Fuel filters seldom suddenly go out like that and prevent a restart. Usual sign on those is high-speed freeway driving miss. Faster you go, more gas you need. If the filter is going bad, you will notice missing and stumbling at higher speeds. That's not always the reason for a high speed miss, but if the filter is going, it's a definite sign.

Pull number one spark plug, leaving on the wire, and lay it against metal. Have someone crank the engine. Getting a good spark in there? This is better done in low light or dark conditions, using a flashlight. No spark, or barely any spark? Check distributor, coil, rotor.

I would start with those things. Changing your fuel filter first on general principles wouldn't hurt though. Might want to run codes, see if anything comes up on that.

Had mine shut off on me due to a fusible link being dirty.
