Stalling with no warning
By the process of elimination I'm trying to find out why I'm getting stalling with no warning. I 've cleaned the sediment bowl and screen, replaced the coil and now I have the carb apart. There is about half full float bowl and the float doesn't appear to be sticking. There were some very fine particles in the bottom of the float bowl. After the truck sits for about 5 minutes it will start but then die. Any ideas? Should I soak the carb for cleaning?

Re: Stalling with no warning
A fuel pressure output test from the fuel pump would tell if the fuel system is working to that point. If there is some crud in the idle circuit of the carb, that could cause poor idling. If the condenser is open or leaking that could cause a weak or no spark condition. From there it would be a cylinder compression check. You'll just have to determine if its either not getting spark or not getting fuel. Compression check will make sure the engine innards are functioning normally.

Your float might be too low or the fuel pump isn't keeping up with the demand for gas.

Re: Stalling with no warning
Check to see if you have any slightly kinked rubber fuel line hose to your metal line.
From under gas tank to metal line, or from metal fuel before fuel pump. When fuel pump gets going slight kink would close off. Just a possiblty. Bob- Hampshire, Illinois |

The fact that it shuts off without any warning makes me think that this is an ignition problem. I hate to see people waste there hard earned money by just randomly replacing parts. Every automotive enthusiast needs to buy a voltmeter and learn how to use it. They are really easy to use and it will eliminate all the guessing. Spend an afternoon playing with one and you will take your automotive diagnosing skills to a whole new level. Jerry |
