Wont start after shut off

I have an 89 C4 with an automatic. It will start ok the 1st time you crank it over but if you turn it off it wont start again for an hour or so. Thought it might be injectors so I checked the fuel pressure and sure enough it drops down quickly but I am beginning to doubt it is the injectors leaking down. If that was the case it should have a flooded smell when trying to crank again and if you give it a shot of starting fluid it will start up again.
Could there be an injector bypass or something that is sticking open? If so is there a way to verify?

Thanks

I would wager that the fuel pump is where your problem is.
