I don’t know where to start well the beginning I suppose
​​​​​​ I got a 92 Firebird, 120,000 mo 305 TPI, automatic trans. I had it stored over the winter and when I went to start it up it would crank and crank no start. What the ****? Haven’t a shot of starting fluid and fired right up. Ran fine no check engine light just ran good. Drove it around every day for about 2 weeks and one day, no start Hugh, popped the hood everything looked fine tried it again and it started right up. Move forward a week or so, driving up to a roundabout on my way to the lung doctor and coming to a stop to merge it died, started back up barely and sputtered enough to get off the side if the road and now it starts Lenore key and it dies right away. Will stay running if you feather the throttle but won’t run in its own.
Befor I go out there with the shotgun troubleshooting technique I thought I’d ask. I am figuring either an IAC, maybe a fuel pressure regulator or a fuel filter. It’s all I can think of. What do you think?

 

First thing is to check the fuel pressure. Sure sounds like a dying fuel pump but could be the filter or pump relay.
