CODE P0300 AND FPR

2003 Chevrolet Trailblazer • 6 cylinder 4WD Automatic • 82,000 miles

Would a faulty fuel pressure regulator cause the code p0300? The problems im having is rought idleing, power loss, electronics are surging and I have gas in the air line so I replaced all the spark plugs and coil to plug boots then noticed that when I disconnected the vacuum line from air box that was connected to the regulator gas dripped from the line

Replace the FPR its ruptured-start here P0300 is normally caused by vacuum leak and contaminated fuel
