Hard to start when hot
 

Have a 79 Targa - 85k miles - seems very hard to start once driven and then sets for about 30 minutes. Car in great shape overall 8.5-9 - but this mystery plagues me. Remove air filter cover and expose metal plunger pump at fuel distribution area - once car is turned on and fuel reaches I manually pump a few times and engine will fire. Cold firing / starting usually not an issue. Anyone have any ideas?

Might want to check your fuel accumulator and your fuel pump check valve. Both will cause similar issues.

Doc,
Thank you, somone else on the West Coast mentioned the fuel pump check valve as well. Any ideas on repair / replacment costs for either / both? Have a good service company locally (Dave White - you may know them) that can service.

The accumulator isn't cheap (around $150 IIRC), but the check valve is. Probably want to do a fuel filter at the same time since you are right there. I would imagine it will be a couple hours of labor.
