How did you check the timing that is dead on-also what is the fuel pressure?

Pulled the timing cover off and checked cam and crank marks
fuel pressure 35psi
injector pule and pulse width looks great as well

I agree but I can hook a compression gauge and fuel pressure gauge a noid light and a spark tester all at the same time and everything is there even tried and egr valve thinking maybe its stuck open letting to much (used) air into combustion chamber to run.

EGR valve could be wide open creating a massive vacuum leak
