The car start good cold but it seem to be getting to much gas it will die when it warm up and not start again till the next day
There good spark I clean all the plugs but I get a dry black stoot on them after running for 15 min The car used no oil so it not oil
I just had to replace the OVP and a wire from the Ign sw to the OVP
The fuel filter was replace this summer and you can hear the pump working:confused:

It sounds like a differential pressure problem. It probably is running lean and has incomplete combustion, this will cause sooty plugs. You need to put a pressure gauge on it and see what the differential pressures are.
