ok lets run thru this now, cranks but doesnt start. have you checked for spark, fuel, and compression yet? is there spark coming from the car, to check pull out a coil and put it near a ground and listen to see if u hear and see spark. for fuel, depressurize system from the port on the rail, prime the pump by turning the key to the on position not turning the car on and press the port fittin with a pen or screwdriver and see if fuel shoots out, as for compression im sure you have that but you can use a compression tester to test it. idk what you have or havent done yet so im jotting down what i would run thru first.
