I am looking at a 100Q to buy I think it's the 2.8 and the guy selling it said that it starts just fine when it's cold but it won't start when it's hot like after it's been running. After I looked on the forums I was thinking it could be the fuel return valve on top of the pump, or maybe the cam/crank pos. sensors? Any other suggestions? Also, how much do you think it's worth? Good cond in/out pearl paint w/ black lthr wagon. Thanx.

could be a temperature sensor. Also check your oil temp and pressure and make sure your running alright.
