Help please ... car starts and runs fine until rain storm or moisture. Following rain the car does not turn or start. I have to jump it and; its as if I disconnected the cables. I have to re-set the radio etc. If it has stopped raining, car starts and runs fine ....till next rain storm.
ANY IDEAS ?

If the car can be jump-started when "wet", the it must "turn" and "start". Sounds like the car may not get enough "spark" to start it when it's damp out. I had the same problem in my '87 5-speed. It would crank when wet outside, but would not "fire". I changed the distributor cap, rotor and spark plugs. It has started fine since then: wet or dry, hot or cold.

I agree, wet start problems are often fixed with new ignition parts.

Clean and replace as required all battery connections and grounds.

Hello,

Replace the battery terminals.

Thanks for all the advice. Appears recent '89 problem was exactly happening to me.
It had to do with; disintegrating insulation on the key and knob lock switches in the drivers door, holding the central locking motors on continuously, or has fits.
