1993
Mitsubishi
Galant
(not sure of engine size?)
100k miles
For a 7 or 8 years now I've had a problem starting the car after a heavy rain, or several days out in the cold/damp. It will struggle but it will not turn over. I've had the car looked at by mechanics and they could see nothing wrong. The car will usually start again once it "thaws" out a bit and the temperature outside rises or the rain stops.
A few other details that may help;
-Problems persists mostly if I don't try and start the car for more than a day or so.
-When I try and start it and leave it for several hours it will usually start upon returning.
-Just had the battery connections checked and one replaced, but problem persists.

Littlegray; When you say 'won't start', do you mean that the engine will crank over, but won't fire? Or, a low/dead battery?
If it cranks over, but won't start, I'd check for spark at the plugs during the failure. Moisture in the distributor cap? Plug wires 'leaking' voltage to ground, ect. Also, fuel pressure, key on..engine off...at the time of failure.

It cranks over but won't fire. It just rumbles, tries, and fails.

Littlgray; You need to determine if you are lacking sufficient spark to the plugs during this failure. If you have a good, bluish, spark during cranking, then I'd look at fuel delivery. Of course, sufficient fuel pressure is first. Fuel delivery to a cold, or warm, engine depends on the information that the computer receives, via sensors. Assuming (I hate that word) that you have good spark, fuel pressure, compression, ect., I would look at what the CTS (coolant temp. sensor) is telling the computer. It could be 'lying' to the computer and causing an overfueling condition, or even a lean condition. You'll need a scanner to see 'live' data. The CTS can be checked with an ohmmeter, and we can supply you with a resistance chart if you want to go that way.
