i87 5kt intermittent no start

[Dave Yentema]

For a while this was only a cold start problem, but as of today it did it whether it was cold or hot

  I'm actually beginning to wonder if the injectors have begun to leak down. If it hot starts well (when the system fuel pressure is still good) and hard starts (lots of cranking, and the fuel pump MUST start up to re-pressurize the system) cold, I'd begin to suspect them. In a garaged car, the other noticable thing is the distinct smell of fuel without a visible leak. The "proper" way to test this is to put a pressure gauge on the fuel system post fuel distributor to see how much pressure leaks down post shut down. Me, thanks to the help of Smitty, I just replaced the injectors, and the hard start issues went away.
