well i took out my after market alarm. and i tried starting it and it is still not staying running. i checked my injector pulses with tester to see if they were pulsing and they were not. im not sure what i should do next. i checked the efi fuse and it was fine. what would be the cause of no injector pulse.

thankyou

Do you have your power to the injectors? Power is constant when running or cranking, and the ECU supplies the ground side. The ground will not be supplied if conditions are not met, such as engine position and speed.
