Do you have spark at your plugs? Have you set your timing from tdc? Check your voltage at coil.Start at your plugs and work your way back. Plugs-wires-coil-voltage to coilIt sounded like zero spark to me on the vid. GL

The plugs for the o2 sensor and one that goes to the coils i believe are the same type. I had mine switched up and it would just crank. Got them switched back the right way and it fired right up. Maybe check that.

Edit: I'm an idiot. Corrected.

Fuel line coming out of the top of the fuel filter should go to the lower line on the front of the manifold.

The other line ( fuel return ) should be hooked up to the fuel pressure regulator which is the top line on the front of the manifold.
