1983 V8 stalls after it gets hot
1983 V8 stalls after it gets hot
I’ll try to explain as best I can.
I work about 20 miles away, and in the morning it drives like a champ the whole time. Does not sputter or act up at all. On the way home however it starts right up and gets me to the point where I stop the car then usually dies. It acts like its flooding, and I say that because when I push the gas to go through the green light or continue in traffic RPM's flat line and usually dies shortly after.
This has only started happening since Utah reached the 90 and 100 degree mark.
It is not overheating, however if I let it sit there for some time it will eventually start back up and allow me to continue on home.
What happens when I try to start it after it dies is just turns over. If I let it sit for say five min then try and turn it on, it will fire up but immediately stall. It has to be sitting for an hour or more in order for it to start up and run again.
As a side note last year I basically redid my fuel system. Had a gas tank that was rusted out. I replaced the fuel pump, fuel filter, gas tank, and had my carburetor rebuilt.
Any help would be gladly received.

What kind of fuel pump did you put on?
If it was flooding, it should start back up if you floor and hold the accelerator down while you crank it (do NOT pump it!).
Often this is an electrical problem, either the ignition module, pick-up coil (both part of the distributor, under the cap), or ignition coil (in the cap).

Re: 1983 V8 stalls after it gets hot
So I took your advice and replaced the ignition module and the pock-up coil. I thought it was ok for awhile however I was wrong, it was just not hot enough.
So it still stalls after getting hot. I will be on the freeway and driving for 30 to 40 min with no issues. Once I get off the freeway is when it starts acting up. First it idols rough and then dies like it’s flooding. However I tried something the last time it died.
I was sitting there waiting for it to cool down and tried to start it, of course it did not start, however I started flooring it and cranking it, also tried pumping it and cranking. Both did not work, however what I did notice is I did not smell any gas fumes like I thought I should due to the flooding. I towed it home and tried to start it again, no go. I then poured some gas in the carb and it started and stayed on.
So my car is starving for gas after it gets hot. I have tried to find a reason and only came up with vapor lock. Now the question is how do I fix this. I’m sure my fuel lines are crap because it’s an old car and most likely needs to be replaced.
So here is the question of the day, how likely is it vapor lock. And what are my options. Would it be easier to replace the whole fuel line, or just find the leak or hotspot?
