    Welcome to the Forum!!! If you haven't already done so, you should read the Sticky "Read Me First!" In there you will find TONS of VERY useful information!!

    Check and report back any ECU codes, check the Air Compressor Line for leaks with a soapy water soloution (when you do get her running).

    Check the engines Compression and also check to see what the pressure of the Fuel Pump and Air Compressor are producing.

    Replace the Sparkplug with a new one gaped to between .035 to .040 (DO NOT go with the gap of a new sparkplug out of the box as it is too narrow and for a generic vehicle use) The plug's gap is important!!

    If this is so, you may have a faulty/failing ECU...

    HERE is a link to my thread that explains what the codes means and items to check...
