Any ideas on why i could be fouling spark plugs? I just changed fuel regulator and fuel filter and oil filter sensor. I just put a new set of spark plugs after i was dead in the water this weekend and the motor shut off and fouled out the plugs within 5-10 mins of running. Anyway to adjust fuel pressure or anytning?

Why did you change the fuel regulator?

Really need to check for codes

Could be any of the ignition sensors malfunctioning
