You've described a 'textbook case' of main relay failure. Resolder it
and you'll overcome a major headache. Meantime, don't lend your Honda to
somebody who is trying to go somewhere important. :-)

The relay controls the fuel pump, and if the power to the pump is
intermittent it will cause the ECU to report problems with the fuel
injectors (sound familiar?) and the engine to run very badly. A guage on the
fuel rail to measure the fuel pressure will tell everything about the fuel
delivery system - including the main relay - and what part it plays (if any)
in your symptoms.

You already know from visual inspection the distributor is bad and from
history the main relay is bad. Replacing the distributor and resoldering or
replacing the main relay could very well be all you need to get back on the
road. If not, at least those known bad parts won't be making you crazy any
more.

The injectors themselves receive their power from termianl 3 on the Main
Relay. All the ECU does is ground them as needed, causing current to flow.

If the solder is cracked and terminal 3 fails to provide power to the
injectors, the ECU sees a no-voltage when it tries to ground the injectors
and sets a code 16.

earlier, you mentioned the ecu giving code 16. that's almost always
main relay.

I've never taken a main relay apart before, so is it a no-brainer as to what
I will have to resolder? Is there a URL or some sort of reference guide I
can read that will tell me about the inner-workings of the main relay? I
just don't want to solder the wrong thing or screw it up some other way.

Thanx,

Jonathan

A Google search for honda main relay gives you exactly what you want.
http://www.markl.f9.co.uk/howto/elec...main-relay.htm is
one of many sites that came up.
