it would not surprise me to find a new relay having bad solder joints.

I doubt that. Honda is not in the habit of allowing defective goods into
its parts stream.

Main Relays go bad through heat cycling and vibration.

solder can crystallize over time.If a relay has been sitting in stock for a
long time,it's solder joints could be crystallized,ready to crack under
stress or thermal cycling.(tin migrates,grows whiskers,too.)

I have not looked at that. Great idea. The Main Relay was new.

Before I changed the main relay the car would not fire at all. It is
firing now, but then cuts off. I have a RPM spike now, when before
the relay I had nothing.

I think the ignition switch is a great recommendation.

Is there a way to test the ignition switch?

Didn't know that.

There's a thread (ha ha) in sci.materials on just that.

If you can turn the switch ever so slowly and find a "sweet spot" where
problems occcur, then the switch may be bad.

put a voltmeter on the wire from the "operate" position that supplies
12 Volts to the engine circuits,and monitor it while you crank,start and
when the motor dies.If you lose 12V after cranking and releasing the key to
the run position,then the switch is bad.
