Can’t make out what it could be, The needle on the gauge does not move when cranking but when you push air into the cylinder, it holds pressure and you can’t hear it leak out of the exhaust or throttle body. Took the oil cap off, no noise anywhere. Cyl #1 misfire on obd II. Changed coil and plug, nothing. Engine shakes badly, very down on power, raw fuel smell from exhaust. Quit working under light load at 2000 rpm, just cruising. I’m lost, any ideas???
