72 Dodge D100 318,

I'm have been having a hard time starting the truck after it's fully warmed up if I shut it off it will fire right back up. If I go into a store or leave it off for 30 mins it takes awhile to fire back up. It will crank and crank and finally start up after a few effort trys (if that makes sense). I have replaced the resistor the fuel pump both fuel filters I've rebuilt the carburetor last year I did a points delete and upgraded to electronic ignition last year as well it just started once the weather started to get warm I believe. I run shell 93 in it. Any thoughts? Thanks

Vapor lock?

When it won't start, if you manually move the throttle, anything squirt out?

Fuel bowls draining out?

Archer,


I do see fuel shot down into the carb when I manually hit the throttle, I have a clear fuel filter befor
​​​the carb and she's nice and fuel with pressure

Fluid in the clear fuel filter (like the Mr. Gasket ones) means the filter is filling, not that fuel is getting through to the other end - don't ask me how I know ...
Just for giggles, repeat the test when the engine won't start, but see how many pumps it takes to stop squirting.
Yes, you may flood the engine.

Only other things would be timing and/or a bad ICU. Yeah, they do go from time to time.
If you can buy or borrow an Orange or Chrome box, swap it in (make sure it's grounded) and see if things get any better.
