I am still wondering what you found wrong with your ignition system? Did the information below from a previous post help you??
Just wanted to pass this along. I spent the last two days trouble shooting/repairing my daughters car. It was taking multiple times to turn the key to get the starter to energize. At first it happened once in a while. Over time the problem became more frequent. She let it go too long and finally called Dad when the ignition failed to energize the starter at all.
The Focus is a 2008 SE bought new with 77,000 miles on it now. I believe this is the first year for the newer body style. She has a sales route with frequent stops and starts her car 30 to 40 times daily so her starting system gets much more cycle time than a normal car.
First, the starter was removed and checked out OK. The starter relay was switched and OK. The neutral safety switch (is a multi function switch) is located on the side of the trans at the shift linkage lever was not touched except to pull the plug, clean and replace.
The starter switch is located on the left side of the steering column directly behind the turn signal switch, it was replaced $43, still no start with the key. (I learned after to remove the starter switch but keep the wires plugged into it. Turn the key to run, insert a screw driver into the starter switch turn it all the way and the car would start.)
The key tumbler felt Ok but it was removed and taken to a locksmith who verified it was OK. However he informed me that a local repair shop had just had the same problem last week and the shop came to them. The locksmith worked on a new cylinder for the shop but that did not fix their problem either.
Since the repair shop was just down the road as I stopped to talk to them. They told me last week they did everything I did on a Ford Escape and finally had to replace the lock housing assembly that wraps around the steering column just behind the turn signal assembly. The lock housing assembly holds the key cylinder on the right and the starter switch on the left and also helps the steering wheel to lock when removing the key.
For just under $150 I ordered the lock housing assembly (part # 9L8Z-3511-A) from the Ford dealer. It comes with the starter switch installed (now I have three of them)but you must use your old keys and lock cylinder. The replacement lock housing assembly can be installed without removing the steering wheel. Here is how....
Disconnect the negative battery terminal.
Remove the steering columns, top and bottom cover and the drivers knee panel under the dash.
Unplug the starter switch on the left side of the column.
Remove the security ring from around the key tumbler by unsnapping it from the housing. Electrical is done.
Three small bolts hold the lock housing onto the turn signal assembly. One bolt is on top, one on the bottom left and one on the right/front. You must use your key to unlock the steering column and turn the wheel to the right to allow access the right/front bolt. Remove all three.
Last, on top of the steering column you will notice an aluminum collar that holds the lock housing assembly in place. On the right side of this collar it is bolted to the steering column by only one anti-theft bolt without a head. (The head of the bolt is gone, designed to break off at the factory when installed for anti-theft reasons so normal tools cannot be used to remove it.) Ours had yellow paint on it. Use a small, very sharp chisel to tap the side of the bolt counter clockwise to loosen it and take it out. DO NOT LOSE IT! You cannot get a replacement.
You should be able to lift up the aluminum collar and remove the old housing assembly.
To use your existing keys you must remove the old tumbles. Put the key into the lock cylinder and turn it one notch only, to the accessory position. On top of the cylinder is a small hole. Put a small torx socket (or nail) in it, push down, pull on the key to remove the tumbler cylinder from the old housing. Put the old tumbler in the new lock housing assembly.
OK, reverse everything and you are done. The hardest part of reassembly was getting the bottom steering column cover back on. I ended cutting a slot on the bottom of it to get it around the steering wheel tilt lever.
I did not find any information on this problem in my internet searches. However, I feel that as these cars age, over time many others will be having the same starting problems caused by the internal moving parts of the linkage within this housing wearing and getting sloppy. The linkage gets loosen up enough that when you turn the key on the right side, the starter switch on the left does not quite make contact to start.
