I may do that. Ok it was idling in the driveway last night an all a sudden it was like you tapped the pedel and out came a smsll puff of black smoke? And if it's parked for an hour or so I will have to pump the fuel filter primer in order to get it to start? I am gettin a p0088 high fuel rail pressure code and all this time I thought it was a low rail pres code! Does this sound like a fuel regulator? And what would cause it to have to be pump the filter primer to start? It leaks a little fuel around the water sensor draincock "sometimes" not always. Could it be duckin air causing it to run so bad? This thing is weak as water at certain rpms and limps often. Help please thanks

Yeah just a little but not always. What would cause it to have too much rail pressure? Rail pres sensor maybe? Or fpr?
