The car will start normally for long time then it will not start. Then it will start again. The battery, alternator, and starter are good. Battery terminals are clean. It seems to happen when it rains and we hit a lot of puddles. But it can happen on extremely humid, misty days. Once it's dry it will start again normally. When it won't turn over it can still be push started and will run normally once started. Sometimes putting the car in gear and rocking it will make it start.

But it doesn't always involve water, but that seems to be when it happens the most.

Next time it refuses to start do below don't wait for nothing something has to give here

Get a helper disconnect a sparkplug wire or 2 and ground it to the engine at least 3/16 away from ground -have helper crank engine over-do you have a snapping blue spark? If so-you have a fuel related problem, check the fuel pressure to rule out the fuel filter/fuel pump/pressure regulator and listen to the injector/s are they pulsing or hook up a noid light. No snapping blue spark continue to troubleshoot the ignition system-power input to the coil/coil packs, coil's resistances, distributor pick-up coil, ignition control module, cam and crank sensors and computer Note: If it doesn't apply disregard it.
