truck died on the road again. help me, please!

what carb? float sticking maybe? tap the side of the carb a little

 

I would think you would notice black smoke from exhaust if your are flooding while driving. If it was driving normaly before, I would check fuel filter, fuel pump, clogged line, dirt in tank, etc.

 

Are you sure it is flooding? Does it happen all the time or only after heating up? If only when hot could be vapor lock.

 

Sounds more like lack of fuel. Try removing the gas cap and running it. Manual or electric fuel pump? If electric is it mounted low near the tank? getting hot and quiting?

 

does it have a vacuum advance? If so disconnect the hose and see what happens. May have a bad breaker plate..or if electronic ignition may have a bad pickup.

 

Filter, Regulator, tank vent blockage possibly?

 

Probably starving it for fuel.

When it dies, hop out and see if your accelerator pump works. That will give you an indication of whether or not it's running the bowl empty.

Also, take a look at a plug right after it dies. I'll bet it's not black.

 

sounds like a fuel problem to me too...filter , pump, or float.... I hope you get it worked out.

 

As stated before, can be a dirty gas tank and pick line is being blocked. Had this happen to me with a '47 Ford - replaced everything back to gas tank, same problem. Turns out that someone had used some gas tank sealer that partly came loose by pick up tube. Soon as I accelerated it died out, start right up and soon as I accelerated again conk out. Replaced gas tank and ran good for years.

 

I would say change the fuel filter! I have had the same problem before!

Sounds like it is gradually running out of fuel for some reason&#8230;. Clogged filter, restricted fuel line&#8230;

 

Just for kicks, pull a plug.

Sounds like you are actually running out of gas, like a fuel pump is failing or clogged filter.

 

I had a clear plastic label off a can of something drifting on the bottom of my pickup tank once. Every so often it would float across the outlet and shut things down. Took a long time and a several tank removals before it floated out into the 5 gal bucket. FWIW

I vote with the rest on a fuel obstruction of some kind. Point of this is don't over look the odd stuff.

 

I had one jump timing on me that sounded like that... drove me nuts looking for fuel problems... check timing real quick?

 

does it stumble and then catch back up? if so its a carb issue, accelerator pump not giving it the juice it needs when you step on it.

if it just doesn't like extra throttle at all, then it could be starving for fuel

if its not a pump filter and fuel line issue, consider a carb rebuild, you could have issues with a float, gunked up fuel inlet valve a number of things

 

Is there a built in filter in the fuel inlet on the carb. My 77 Ford had a aftermarket filter I installed that filtered nothing. Screen Filter in the inlet fitting was almost pluged. Acted like yours. Pull it out and see if you can blow through it.

 

Did it run ok before you filled it? If it did you have water in the gas. Put a couple cans of heat in to take the water out

 

if it was flooding you would smell it,i suspect flow problem also.wasnt the truck sitting for a while?ive got this two barrel looking for a home if its a fit.i know its a runner and it was given to me so i can give it again.bolt pattern3 3/4 across the front 2in front to rear.

 

My guess is lack of fuel.

Do you have one or two fuel filters on it? A lot of people forget about the filter IN the carb. It's usually behind the big nut where the fuel line hooks up.

It could be a pin hole in of the fuel lines. Climb under it and look at every inch of the fuel line from the tank to the carb. If there is a wet spot there is a hole. If fuel can get out, air can get in. I just had this problem on my beater truck. It had similar symtoms.

Good luck.

 

Mark,
Sounds like you may have crap in the fuel tank. Had the same prob with my GMC when I first got it (first gear, second gear, third gear... die). Couldn't flow enough fuel to keep it running. REmoved and blasted all the sediment & rust out of the tank and never had that problem again.

 

remember your idle circuit doesn't take much fuel, might be just enough getting through to let it idle but not enough to run, they sell a good diagnostic gauge from actron that measures both vaccume and fuel psi, it's pretty cheap,most auto parts stores have it. t it in and watch the gauge pressure when you hit the gas. that will tel you a lot.

 

Sounds pretty typical of a cracked fuel line right at the tank.
