Wont stay running

I just got the car re registered for CT from Florida. It sat for about a year with intermittent periods where i'd take it for a ride. I took it out earlier this week, and it ran fine except the battery was dead so i jumped it. Took it for a couple of blasts up the road. It ran out of gas a little while later idling in my driveway. I Put a half tank in it, it started running like ****. I put two bottles of dry gas thinking there would be moisture in the tank, that didnt help. I filled the tank up the rest of the way today with shell v-power and two more bottles of dry gas. It still runs like ****. It turns on revs to 1500 drops down and almost dies, sometimes it does die. It just keeps doing this, there ar no ses lights so i dont think a sensor for anything is bad. Any ideas?

Might try changing the fuel filter. It might have sucked up crap from the bottom of the tank. If that fails, check fuel pressure.

I'm talking pressure from the pump. There should be a port in the fuel line next to the fenderwell on the drivers side if you have an Lo3. You'll need a fifty $ fuel pressure tester or a good friend that has one. Should be 9 to 13 lbs pressure. Less than 9 you need to change the filter. If that doesn't help, a new fuel pump will be in order.
