My 97 cavalier manual 2.2 does not want to start if it's been raining. The engine turns over but then either won't start or it will take a handful of trys before it starts. I've only had this problem when it's been wet outside.

Re: 97 cavalier won't start when wet
That is your distributor cap. It either has a crack or isn't tight. The rubber seal could also be shot. Condensation from outside moisture builds up inside your cap while it sits. It wastes the spark on the water droplets instead of your contact points. Next time it happens, take the cap off and wipe it dry on the inside. Don't take the wires off. If your going to change it, label each wire starting at 1 mark. Hope this helps.

Sounds like possibly more than on problem, crankshaft position sensor, or ignition module likely on starting prob which maybe affecting shifting due to hard code in ecm, or shift prob could be shift solenoid in valve body of transmission. Both parts readily available from local parts store
Hi, the most common reason for a car not starting in the rain is found in the spark plugs. Wire insulation can wear thin and this causes the voltage to arc to the metal of the car engine rather then going into the spark plug. You can check for this visually by opening the hood when it's wet outside and trying to start the car. You might be able to see an arc from the spark plug wires.
Secondly check the distributor cap. Take a good physical examination of your distributor cap for any signs of a cracks. Also remove the distributor cap and check the inside of it for moisture. If you find any, wipe it clean; it won't work while wet.
my next step is to MANUALLY attempt to see if this engine will turn. Disconnect battery, remove starter completely which will expose the flywheel. With a HEAVY flat blade screwdriver partially inserted by a tooth in the flywheel, exert pressure in a pivot movement trying to move the flywheel . If it doesn't move the engine is seized.
