Let me explain a little more...
1st- PCM is set to stock 99 L67 file w/ LQ4 MAF and 42.5 scaled on the injector table
2nd- yes there is spark but timing is off so bad smoke is coming out the valve cover which leaves me to believe the exhaust is exiting partially out the intake valves. It gives a loud backfire after awhile of cranking. During firing it hits a dead spot every time it goes through all 6 cylinder and lands on one. (hear the video) Sounds exactly like having timing retarded too much.
Scan shows 10* timing exactly when cranking across the board.
3rd- There is vacuum showing on the scan but this does not eliminate all vac leaks I know.
4th- Fuel pressure is 42ish when cranking (adjustable regulator)
5th- Coil packs and wires have been checked and are installed correctly.
BTW yes it was flooded after a while but holding the gas to the floor will clear this out which we did and tried again.
