Sounds like possibly the fuel pump is not working properly, or the fuel filter may be clogged up. Then again, you say you were working under there, so you may have moved a wire, or loosened a connector without knowing it. Check ALL of the connections on the throttle bodies, as well as the distributor.

Ya, what Joel said.  I did not think of the fuel pump.  But then again, I am not the all powerful Joel !!!

I have an '82 and ran into a similar issue about 6 months ago while the car sat around getting a new interior.

For a while, the car would not stay running, yet what fuel did get to the throttle bodies, was quickly consumed within seconds. We then started the troubleshooting and while we had the chance, the mechanic changed out the idle air controls and replaced the coolant sensor. Although fuel continued reaching the injectors, the fix was a false positive. The car would start, and would immediately consume what fuel made it to the engine, then shut down. The fix??

Thanks for the info guys! It sounds like the conditions I have mirror those that you described Jack. My car sat in storage for nearly 3 years and I just started working on it within the past two months. I'll start with the pump and work my way forward... 

Yes! good to know! I've been, nope not gona jinks it! Thanks John

I'd change the fuel filter and give it a whirl. LFTSSF!! (look for the simple sh&% first!)

You can remove the fuel pump from the tank without removing the tank.

I'd say put a pressure gauge on it and see what is going on. Loosing fuel pressure could be caused by several things, including a bad oil pressure sender, a faulty ignition module, or the pump/filter. If the engine starts dying before the fuel pressure goes away, then you're looking at another problem, such as ignition related.
Have you "scanned" it for any codes?

Thanks Jack, you nailed it right on the head. I pulled the fuel pump and there was a 1/2" split in the side of the rubber hose between the pump and rigid fuel line. I replaced the hose (and clamps) and I'm awaiting the tank gasket before I put it back together. That should take care of the problem!!!

While you are in there you may want to replace the fuel pump with an 1985.  It pumps more volume and will keep the pressure steady.  I put on a pressure gauge.  When I went through this I found my pressure was close to 6psi .  The car would stumble when I hit it hard coming from a stop.  I replaced the fuel pump and got it all the way to 9psi then adjusted the fuel pressure to about 12.5psi runs soother but I have a little high 750rpm idle problem.  By the way my local auto parts store had the fuel pump for about $50 with fuel sock.  Do not forget to replace that it is cheap and you do not want to into the tank again for that.

 What great information Jack!!  I, for one am glad that folks like you and Joel are on this web site.  I'm learning new stuff every day!!  Who said I was too old to learn stuff, was that you Ebo?????
