Mystery Diagnosis.

Battery has juice. Tapped the starter and still didn't start. Was running fine day before. Did rain last night. Any guess why it wont start?

Re: Mystery Diagnosis.

In the few times that's happened to me.. it was always a poor connection of the secondary wire coming off the positive, that goes across the rad support to the ignition.

May not be your problem, but a good place to begin.

Re: Mystery Diagnosis.

If it rained HARD... check for hairline cracks (or worse) in the distributor cap. They can let moisture in and cause it to not start.

If you're not sure, take off the cap, blow dry it, then re-install and see if it starts. Sounds stupid, I know - happened to me though. Truck kept drowning out over puddles, and this turned out to be the problem.

I also hit the inside of the distributor cap with WD-40. The L6 design, with the distributor on the side, is prone to shipping water when splashing thru intersections and fording wet draws.
Check your battery terminal connections. Wet weather can hasten corrosion of the terminals and leads.

Re: Mystery Diagnosis.

Every once and a while, the starter lead on the back of my ignition switch works out a little bit. The first time it happened it stumped me for a while. Now, I think of it as a kill switch.

Re: Mystery Diagnosis.

Yeah he's right, the selector on the column is off track. It was just as simple as giving it a little nudge to make sure it was all the way in park and vroom I was off to the races again.
