Default My 1993 Honda Del Sol periodically just won't start. Seems to happen when it's rained. Any thoughts?

Not giving any codes. Not the battery or alternator. Just won't crank and run. Let it sit for a few hours (or a day or two) and it starts right up and runs fine. Mechanic seems to be stumped.

very often that is sign of cracked dielectric ( the plastic ) you cant see the cracks ,, on one of the ignition parts ,,like the ignition coil ,distributor , etc.

it is caused by the higher humidity when raining , the moisture gets in the micro cracks and caused the " spark " to short circuit and the car will turn over but will not start.

then when it dries out , it starts up like nothing was ever wrong.

one of usually temporary remedies is to spray " WD 40 " generously on all your electrical components like the coil , distributor etc.

you prob have heard of WD 40 before . people use it for all kinds of things, sold everywhere.

Well the WD stands for " water displacement " when you spray it on the " plastic parts " of the elec parts . it displaces the water in the cracks with the light oil in WD40 and the problem goes away.

you mean to say your mech as never mentioned this as a possibility ?

if this is the problem , you have to replace the coil or what ever has the cracks in it.

if your car has a distributor cap ,, you remove that and spray inside that too. if you have a dis cap . that or the coil is usually the problem.

moisure collects inside the dist cap causes this problem.

if you have an old distributor cap , which you do if you have not replaced it. just start out by buying a new dist cap and rotor , they are cheap. just look online.

also they are very simple to replace , you could do it yourself or have a friend help you. very easy.

google you tube videos to show you how. also if your spark plugs are old and cracked .. put some new ones on at the same time.
