I can’t wrap my head around why it’s not starting it crakes over and I’ve doubled and tripled checked all wires and timing. I don’t think it’s a bad starter with it cranking over. I’ve checked the battery and put it to trickle charge over night.

if anyone has any suggestions they would be much appreciated.

 

you're sure the timing is not 180° off? "UP" on the cam pully at top when marks are aligned?

you checked compression?
you confirmed fuel in the cylinders (injectors firing) / wet spark plugs?

 

did you reattached all the ground?
