Sounds like a good place to start would be a new set of plug wires, distributor cap, rotor, depending on what ignition system you have, plugs too, if not done recently.

2006 ford free star when it rains the PCM gets wet and runs rough. Today it has rained for 3 days @ won't turn over. Battery is fine. Only a problem when it rains.


Rain should not affect your car starting. It sounds as if your battery is failing. Put your headlights on and get someone to turn the key with you looking at the headlights. If they dim to a glow-worm, your battery is not powerful enough. Sometimes a cell will fail and although your get 12 volts, you don't get enough cranking amps.

Regarding starting in damp weather, you can try this. Spray all the ignition leads with WD40 and also the inside and outside of the distributor cap. You can also try this which worked for me on an old Datsun that didn't like damp weather. Get some broadsheet newspapers and tape them together to make one large cover for the engine compartment. Make is about 10 sheets thick. Run the vehicle with this all over the winter. When you drive the paper warms and keeps the leads warm. When you park, any moisture in the air goes into the paper and doesn't condense on the ignition system. Make sure the paper is away from moving part like the radiator fan and the exhaust manifold. Check it after your first short drive, it should stay in place.

My 2002 Toyota Celica fogs up and collects moisture on the windshield during or after a rain. Visibility is a major problem. Need help, this is truly unsafe.


Can be that your heater core or hose inside car is sometimes releasing alittle heat at the clamps. So long the inside of the floor is not wet or damp or car is not over heating. I would not worry about the heater to much inside unless this does not work...
Change the automatic climate control up or down to cooler or warmer i usually run it at least upto 10 or 20 degrees different than the outside anytime i drive mainly during rain or snow.. So if outside it is warmer means you need to be cooler and cooler means get warmer. Also If you don"t run that on a regular basis a quick Ac on and defroster front and back works well and generally fast.I really think that is all of your problem just get comfortable with your automatic climate setting. once in a while it may happen again only because of rapid temp. changing from outside air to inside air in your car..Rain X works really well for a couple weeks between apps.and saves wiperblades during raining times. Always drive safely and good luck 11_21_2011_5_34_27_pm.jpg

1998 GMC Suburban. Did an oil change about a month ago and then changed the spark plugs, but now the car won't even start??? I have no clue now.


When you initially turn on the ignition switch,(before engaging the starter) do you hear a humming sound from the rear of the vehicle for about 3sec's? (sort of like a motor running) If not, you have a bad fuel pump. (The fuel pump is located inside of the fuel tank)

Jeep wont start when it is damp or raining.


It is probably your ignition wires. When moisture can penetrate the wire it shorts is out. Check them for cracking and especially where they are close to the exhaust manifold. I hope it is due for a tune up, this should take care of the problem. If not, you may have a dirty connection in the ignition circuit. Check all you connectors for corrosion and spray them out with a penetrant/moisture chasing lubricant.

My 99 Suburban is intermittently starting.....


Unfortunately the fuel pump can still be bad. The pump has a check valve on it that wears out. The pump will continue to run but, struggles to supply enough fuel to start the engine. You can buy a fuel pressure test gauge from Auto Zone or that type of auto parts store and check the pressure. You can purchase a fuel pump from them too.

1998 318 Dakota hard to start in/after rain


Check the distributor cap, u can have a very fine crack that allows moisture to enter on damp days and make starting difficult. Look inside cap w/ good lighting, u can usually see it if u look carefully. Let me know what u find.

Starts hard when it rains


cover the distributor cap with plastic and the high voltage coil.

with a damp environment, high voltage usually jumps to the nearest ground and would not go to the spark plug.

you can test this at night when it is damped and raining, at night, let some body start the car for you and you watch the engine compartment without light so that you can trace where the spark is jumping out.

tnx 4 using fixya,
