Ok at first the motor would startand die right away time after time. I was told by folks on here to check and change if needed fvs hi press pump and reg. It was gelled feeul in it so I cleaned it out,put new pump and reg. Pump runs when key comes on, and have good press out of hi press pump. I oull plugs and have spark at plugs grounded to block? I'm stuck? I am a auto mechanic for yrs but this is throwing me? I have air ,fuel,and spark? I did pull two plugs and it fired once just hit not run, so I put all plugs back in thinking it flooded ,and nothing! Just cransk! Battt is brand new.
