Sounds like it is flooded.
1. Try starting it foot to the floor on the gas pedal.
2. If that does not work, disconnect the MAF and try starting it with your foot to the floor.
3. make sure the water pump bearing has not siezed (my LWB did this and died--only time it was ever on a tow truck).
Report back. I PMed you my cell.
