Re: hard starting when hot

Turn the headlight on when is acting up, if they dim a lot then the starter might drawing a lot of amps. D you have headers? High heat can cause problems like that. Check your cables or corrosion & tight connections.

does it crank slow or normal when its hot? if its slow, i would assume something is drawing alot of juice. if it normal might be a problem in the fuel system. could try testing injectors, when was fuel filter changed?
