..still looking for more possible causes if anyone knows anything

i have spark and it is timed as i watched with a light while gf cranked it, and i did the injector test and heard it.

what controls injection timing besides cam sensor and crank sensor, i have spark on time and 42psi fuel pressure between the two rails while cranking. someone also told me i could check for pulse by turning distributor by hand and i could here it. still no start. cranked for 30 sec and not even fire ...

so if i have injection, how i can make sure its on time. I even pulled distributor apart to make sure everything is lined up and tride and different cam sensor and the same time

well i could here them hiss but the strange thing is that i had them unplugged from when i tested for voltage?

if i dont hear anything that would mean cam sensor? there also is no codes

What should the compression be? If i turn dist by hand the injectors should pulse is what your saying?

well im not seeing any other route i tried the meter on and off and it moves by hand freely

timing is 7-9 degrees advance while its cranking, tested maf as per service manual and tested within limits.

so i have spark and on time while cranking, fuel pressure 40psi while cranking between the two rails, no air restriction. it did die as if it were running out of fuel. i checked all sensors and relays that have to do with the injectors, all tested within spec. im lead to believe ecu is at fault ...
