Ok i have a 94 olds 88 royale with the 3800 in it. What happens is sometimes the when u turn the ignition on to start the vehicle all the dummy lights in the dash start flashing relays start clicking ect. and the vehicle will not start. If u give it about a quarter throttle it will start and run real rough if u hold the throttle in then eventually it'll run just fine. I have replaced the battery cables checked the grounds in the engine compartment replaced the throttle body gasket because it was leaking coolant from there and still this problem.. I had a friend scan the codes and it gave a code that said anti theft system shutting down the fuel pump. He has no idea what this means and im thinking maybe ignition switch but i dont know. Any suggestions would be very helpfull here.:disappoin

Welcome to AF. Try and post the exact code for additional help here. Also does the security llite stay on when this happens?

I think that is - O2 Sensor Circuit Malfunction (Bank 2 Sensor 3).

Your car is OBD 1 , so I'd have too look that up.
autoxray's not the best either.

And this, sounds like your battery isnt fully charged or you have connection issues.
