help i keep stalling out!
« on: January 17, 2011, 03:34:49 pm »
As I write this I am trying to drive home and my engine keeps stalling. Its acting like its starving for fuel.

Considering I was just driving it all day yesterday I'm thinking its the fuel pump or the fuel filter I the carb.

If the filter looks clean, how do I know if its the pump?

78 c10 350, auto.

Helpppp!!!!

What do you do when it stalls? Stopping, accelerating, coasting, maintaining speed, etc?

Well it did it like 10 tmes on the way home, so I got a few chances to try different things. Coasting still killed it, mashing the pedal still kills it...however, mashing it down if and when it finally starts is the only way it will stay running long enough to go into gear and go maybe 100-400 ft before stalling again.

Took the fuel line off at the carb to see how much the pump pulls on startup and it was a pathetic trickle,,,wouldn't really even call it a squirt.

Very confused.

Did you ever fix or replace that fuel line?

you saying you cranked it over while you had the line disconnected? If you only get a trickle with that then you need a new pump.

Make sure the rod is pushed up into the block. Also you can buy a length of steel line with fittings already installed. If you cut the line and use a short piece by the carb to replace that kink you can splice the 2 lines with fuel hose and clamp it together, or bend up a whole new line if you can't find a pre-bent replacement.

Replace that kinked line. All you need is a piece of 3/8" and bend it.

I will bet whats happened is that pump trying to force the fuel past that kink has killed it, Mine was the same way . I replaced the line and the pump and everything is fine.

Can I use a few inches of reinforced rubber fuel injection line? Just to replace the 90 degree angle.

As long as you have enough room to get it clamped properly, and the hose is rated for fuel. I know a guy that burned down a real nice Monte Carlo because he was stupid and used 3/8" air hose for his fuel line. The ideal setup would be to use all steel tubing.

Replaced the pump and fixed the kinked line. Started and ran fine for 2 minutes then died again. Still acting like its starving for fuel. Its even hard to start too...

Is there a filter I'm missing that might be clogged? Could it be electrical?

Unhooked the line to the carb to check the flow and its still not pumping fuel. I took the pump off again to make sure the rod was positioned correct...still not pumping.


I have gas. Its a new pump. I fixed the fuel line.

the fuel sending unit can't have anything to do with it right? Unless its clogged solid?
