Greetings,
I have a 1996 Pontiac, Firebird, Formula, 5.7, 350. Upon starting it cranks constantly but just will not start. I have replaced the fuel pump and verified the fuel pressure delivery. I also did the VATS resistor bypass. I also did verify I have spark at the plugs. I suspect that the injectors are not letting the fuel into the engine. Any assistance would be appreciated.
Thank you.

Another key if security system is still hooked up then check fuses under hood check resistance of crank sensor should be 800-1200 ohms and do a wiggle test on connection as it may be bad or poor. Check coolant sensor for ohms as well see pics even though you replaced pump check at rail with a gauge auto parts rent it. 41-47 psi key on
