If your car is equipped with a 2.4L Quad 4 engine, you most likely need to replace your ignition coils. They are located inside what is called the "IDI Module" This is the large cover on the top of the engine that says "Quad 4". The ignition coil housing and spark plug boots should also be replaced. (See pictures below)

To replace the coils, disconnect the IDI electrical connector (Driver's side of the IDI Module) Remove the 4 bolts retaining the IDI Module to the cylinder head.

NOTE: be careful not to loose the washers under the bolts. Sometimes they will stick to the IDI Module and will fall off when you remove it. It is best to take a small screwdriver and get them loose before they have a chance of getting lost. Trust me...It happens all the time.

Remove the IDI Module from the cylinder head and flip it over. Remove the 4 screws holding the coil housing to the IDI module and remove the housing. Remove the screws holding the ignition coils and remove the coils. Reverse procedure to install.

That would be the ignition control module and its exspensive so make sure thats the problem.I would check the fuel pressure first it should be 41-47 psi with key on engine off.If its not within these specs replace fuel pump.

It sounds to me like the sending unit in your gas tank is getting wet and shorting out. Hence, why whenever it rains it can't get fuel.

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.

I suggest that you look for secondary voltage leaks from the ignition system. Moisture causes dirt to become a pathway for this spark voltage. Look inside all wire connections, for any corrosion. A scope can test this, but typically a home does not have a scope...

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.

Starting in damp weather 1993 240 wagon, auto/od, 235k miles


perhaps you need a new cap and roter a new spark plug wire set. they don;t like moisture. also check to see if you have any broken or leaking vacuum hoses. the worse case senerio would be that your head gasket is leaking--at cold temps a little antifreeze will enter until everything warms up and it seals shut due to metal expanding. but since you say it's cold weather only--this probably wou;dn't be the case. good luck.

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.
