I can dump gas in the carb and it will start and run for a few seconds. Have power to the pump but it does not run when key is turned on. No fuel in line. Fuel filter was also replaced.

Is security light on/flashing or does dash look normal?

Customer: replied 1 year ago.
Had a check engine light on for a while. Not sure about security light...You mean for a car alarm?
Expert:  Dan replied 1 year ago.

Correct, for car alarm. The security system can disable injectors but that usually causes vehicle to start/stall. Next step would be to check fuel pressure, pressure should be 60 psi key on engine off. Let me know, thanks.
