fuel is getting cut off after a second or two...any ideas why?
I've got an '89 RS 305 TBI. I rebuilt the motor this spring and it ran for a few days and then wouldn't any more. I had a mechanic working on it as a side project, but my daily driver broke down so now I'm stranded so I would like to get the camaro running.
What's happening is that I try to start her up and she cranks and the injectors fire enough for her to start, but then the injectors stop spraying and it just dies. I tried revving it a little bit to maybe keep the fuel flowing but it did the same thing.
What could cause the fuel to be cut off? Any ideas? I could really use any advice you guys could give. Thanks.

It sounds like your oil pressure cutout swich is gone. When you first turn on your key the ecm runs the fuel pump for a few seconds to presurise the fuel system so you can start the engine. After it is started there is a oil pressure switch to keep the fuel pump relay on. It is designed to shut down the engine if oil pressure drops too low. If the switch is not keeping the fuel pump on the enigne will only run for a few seconds.
