Spray some starting fluid in the intake to see if you have a fuel or spark problem.

I did that and it does the same thing before and after changing the fuel pump

fuel pump pressure is fluctuating perhaps down to zero-

Doesn't this design have a fuel rail with a shroeder valve on it?

What's going on with the fuel delivery?
