I have a 97 trition drove it home it was fine couple of day later it wouldn't start. Replaced the Crank and fix up timing then had to hot wire the Cam sensor it started! yay!

Few days ago it wouldn't start again.. strange nothing been done to it. My Mechanic is loosing his **** over this
We have done:
Fuel and Fuel Pressure.
all fuses.
checked Cam sensor again.
Roll over sensor.
Ecu checked ( ECU has constant power when off and none when on)
probable other things but i just cant remember..

Spark comes and go after turning it over.
Put start ya bastard in the air filter and it'll run for 2 seconds.
No injector pulse

Any help is appreciated!
