3.0L V6 OHV Aerostar hates soggy weather
Disregarding everything else about the Aerostar, I want to focus on why it is that it will start every single time, all the time, no matter what, in dry weather. If I drive it and then it rains upwards of a half a day later, I can drive it as soon as it starts raining. If it sits for over a day, but only if there'* rain, it absolutely will not start normally.
Now, to explain "normally." The engine just turns over a few times, and things start running every time I need to haul something. However, when it rains, the van absolutely cannot start like that. Instead, it turns over for a good 5 minutes before it starts, and then I'm out of an eighth of a gas tank.
What are some troubleshooting steps for this?
