My van wont start whenever the air is damp. I have replaced the spark plugs and wires, rotor, dist. cap and the mass air flow sensor. Do you have ideas on what else I can check. No codes show sense it hasnt started when it is having the problem. On dry days it starts right up and runs good.

Hi
Try this on dry day engine starting get a spray bottle with water. Spray then Ignition Control Module they try and start if starts do same to crankshaft sensor.
See diagrams
Let me know
Thanks for donate
Thanks alot, man! You probably saved me hundreds that a mechanic would have charged. I sprayed water on the crankshaft sensor on a dry day like you advised and it didn't start...put a new one on and sprayed it and it started right up. The real test will be in a few hours when it rains, but I'm pretty sure that fixed it. You know what you're doing! Thanks again.
Glad to have helped Yea could have turned into a Money Pit. Come back if you need help in the future
I was wrong...it is raining today and the van would not start again. The only thing I havent replaced is the ignition control module...any other ideas?
Check out vehicle control module left side engine compartment. See if rain water getting on VCM. pull connectors see if its wet.
I checked out everything i could see without taking it apart..nothing seemed wet..i give up..taking it to a mechanic tomorrow..thanks anyway
