I don't think you should lose pressure so fast after the engine is shut off, you may have a leaking injector. Is this a Vortec central-point fuel injection system?
Make, model, year?
The CPFI vehicles are EXTREMELY sensitive to fuel pressure. I seem to recall a difference in 2 PSI making the difference between a start and a no start.
56 PSI seems about right IIRC for engine running. Pressure should not drop to zero when it's shut down.Found entire kit at a local parts place (Borg Warner replacement) Talk about $$$$. Whew but...this is the fix. I can see how it would draw air/fuel instead of jsut air in the plenum when the regulator is leaking.
Putting kit on now on a nice day. Long live the mechanic!!

Well, I found another regulator/injector assembly for $100 less and looked exactly like the Borg Warner one, same materials etc. so I went with that. Still 300 bucks though.(aftetr adding a gasket to the list)
