hard starting when warm - 11/08/11 02:58 AM
After driving my 70 challenger 440-6 pack, I shut it off and when I tried to start it again when the engine was warm, it wouldn't start. When I tried to start it when warm, it would just crank over and over.
I had to wait till it cooled off before it would start. Any suggestions would be apprecited.

When my dad's car had this problem, we searched for vapor lock etc., nope.
It turned out the reluctor gap in the MP distributor was too wide. We set it to spec .008" and it was fine after that.

Starting ether will get anything started as long as the ignition still works!

Do you have a vapor separator? I had this problem with mine and it turned out the return orifice of the vapor separator was too large. After a hot shut-down I guess it was returning enough fuel through the return hose to not supply enough to restart the engine until it cooled. I put a hose clamp on the rubber part of the return line right after the separator and clamped it down hard enough to block off the return completely and it fired right up and ran like a champ. I've heard from others that this can be a problem with repro vapor separators.

I had this happen once, too.
As did I. For some reason the reluctor gap only affected hot restarts.
