Re: MPI DOESN\'T WORK--PLEASE HELP.
Seems to me you're getting excellent technical advice here, which I wouldn't pretend to be able to add to.
What I can tell you is I think you're smart to just set it aside for the evening and do something else. The worst messes I've gotten myself into, working on rigs, is pushing things to the point where my emotions start to over-ride my thinking. This usually occurs late at night after hours of careful work have not gotten the engine to start, or the switch to operate the solenoid, or the spring to fit properly on the perch or whatever.
The best mechanics I ever met were all guys with a super calm, patient disposition. I lack that valuable trait, but I did learn to compensate by putting the tools down when I got frustrated and started to get angry.
It will all still be there tomorrow.
