This afternoon outside temp was at least 94. the car took a long time to start:crank, pump, wait, pump, crank, curse, crank.
Finally started, when I finished my errand it didn't want to start again. Vapor lock?? Is there a cure?? thanks, |

If the pump is in the back, it is not protected from the heat of the exhaust and under engine heat, so it can be vapor lock.
Do you have ethanol laced gasoline is your area? It perculates at a lower temp and could also be part of the problem in a carbed car. I'm investigating going to an EFI setup on my 2.7 engine as it really doesn't seem to do so well with the old Webers anymore. |
