i have a 94 lude h22a vtec and for some reason it wont start if it has rained at all. if it rains the night before my car wont start in the morning but as long as the rains all dryed up it will start? i have change the ingnition module and coil but still no luck. I was wondering if the main relay could be the problem but i figured it would die every once in a while if the relay was bad from some of the other posts, cuz car seems to run fine once it turns over.


if anyone has any sugestions that would be great thanks

I would make sure all your grounding points in the engine bay are clean and making good contact.

The ECU may be the culprit. If you have access to a "loaner". Have it yours unbolted and ready to swap out when it doesnt start. Also for kicks, check G101. This is the main ECU ground. Its bolted to the thermostat housing.

not so true about the main relay. usually once the car starts it wont die because the cracked solder in the relay has fused back together from the power running through it. but i have heard about ecu's not working after rain because a leak in the car or because the ecu isnt sealed enough to keep out moisture. try opening up the ecu and drying it with a hairdryer. if that doesnt work then its the main relay.

check out the cap and rotor... when its seal gets old, moisture gets in and will cause issues with the dizzy.
