Ford Ignition cylinder issues
Customer came in yesterday stating that their car would intermittently not start, and that now the problem has grown into a more regular issue, however if the shifter was moved around enough that they were able to get it going. I get it in my bay and shut it down, and big surprise it doesn't start, cool. With no codes stored I just starting going through some data, and to my avail, it was showing that the vehicle was in third gear. so I proceed to go to the range selector switch and do my tests from there.
After finding that I was missing a power feed to the selector, I checked and it happened to be the power feed for the control side of the starter relay. So I check where power goes in from and it comes from the ignition switch, no problem get to the ignition switch connector, and verify that I have all my inputs present but I am missing the output to the trans range switch. After not thinking much of I get an ignition switch install it, same thing. by this time I check scan data again and find that it now says its in park. so I supply that feed wire with power car starts right up, do the same thing in every range and vehicle only starts when it should.
Back to where I was with this I started to take a closer look at the ignition cylinder and found it to have some play but didn't think much until I took the ignition switch out and started the car with a screw driver. there is a rod that's part of the whole housing, that was so worn that it wouldn't rotate far enough over to move the ignition switch to the cranking position, so what started out to what seemed have been a range selector issue is now a ignition cylinder rod issue. I found no TSB's regarding this issue, and when speaking to the dealership they make it seem as if its a common problem, first one I've seen have this issue. learning curves I guess has anyone else ran into this before??
Yes, I've definitely come across this before, but all were older Fords. 2010 Focus would be a 1st for me. I have seen a variety of column parts wear or just plain loosen on the Fords in general. Most I come across are E&F series with these issues. The Explorers have a sensor in the lock cylinder area, which likes to break off its hold-down and keeps the shifter from going into Park or
Yes, twice on Ford Escapes. They will usually start if you turn the key extra hard, unless of course the driver was already doing that for a month (or six). IIRC, in typical Ford fashion, the part has a strange enough name that it is very hard to find for less experienced parts people.
did they call it a "steering column lock module" ? That just popped into my head,
I have not seen that in particular, but I had an Escape (don't remember the year, probably <10 years old)that would not start unless you pushed the key straight in towards the column with extreme force while rotating it. It got so bad by the time the customer decided to fix it that I could hardly get the car started to pull it in. This piece that goes behind the lock cylinder was worn into a
as4z-3511a is the ford part number for the ignition piece that wears. It was awhile ago ,they may sell it complete now. You can see the piece that wears .The throw is effected.
Right, that's the entire housing, which is what I ended up replacing.
