Ok, we need to look at the back pressure in the exhaust for possible restriction. You can get a back pressure gauge and insert it in the o2 sensor port and measure. It should not be over 1 lb

Fuel pressure is good timing is on and have a good spark -But are the injectors pulsing-clogged exhaust will prevent it from starting the engine is not breathing properly.

Timing is dead on-how did you determine this?

No backpressure gauge -disconnect the exhaust pipe from the exhaust manifold and see what happens
