no fuel inj pulse while cranking
i have zr1 engine swapped into an older c10 truck, tuned previously on the car the pullout came from, i have a standalone harness. i have disabled the starter, and vats under os and system tabs and done complete write. has spark but no fuel injector pulse remains on 0.00m/s. the map, baro and boost sensor are at 99kpa which is correct for my elavation, i have crank and cam rpm while cranking. fuel pump is coming on but i have no light on a noid light, i do have voltage at all injectors but no ground pulse.
please help i have attached the tune file.

I would suspect a cam sensor trigger issue. Maybe look into that.
