4k won't run

The fuel pump seems to be working.  It's getting fuel to the fuel
distributer.  One strange thing did happen, but it only happened once.  The
car tried to start itself, the key was off, the engine turned over and
started running for a couple seconds.

A Bentley manual would definately help, but I don't think we'll find one
locally.  We're trying to get the car running for a rallycross on Sunday.
