Ignition switch and Engine "run-on"

[nhmartin]

1991 Ford Explorer. First problem began several months ago when the ignition switch wouldn't crank the starter. Nothing would happen "sometimes" when you turned the key over. If you would jiggle the switch back and forth several times or real quickly, then it would engage the starter. (Starter is new, battery is new, starter solenoid is new).

Second problem maybe related to first...Recently engine has begun to "run-on" after being cut off. Doesn't happen every time but maybe once every 15-20 times. You can remove key from ignition and car will just continue to "shake and rattle!" Just had car in at Ford dealer and they failed to simulate either problem or could offer no explanation as to what the problem might be. Unbelievable after two days. I had suggested it must be an ignition switch problem (at least the first one). They thought that it was possible but didn't recommend changing the whole key cyclinder etc. without more positive proof and too costly. They were convinced that they could not diagnose the problem unless the mechanic could see the problem occur for themselves. Good Luck...

Needless to say I was livid, it's my wife's car and the only respectable Ford dealer and service shop for nearly two hours from where I live. (I mean formerly respected service provider).

ok, i think it is a loose wire somewhere....if it worked when jiggled it probably was able to complete the circut.

problem 2...it runs on becuase the connection wasnt made that it ever turned off....

could also be a bad ground

Loose wire in ignition switch

Thanks for the quick response.

Makes a lot of sense but don't you think a dozen "certified" mechanics and two days with the truck could have resulted in some kind of similar investigation.

Maybe these guys just have too much work and not enough time to really deal with "intermittent problems"?

How can I pursue this on my own?

ok89 a member on here went to ford and said his starter was blown...the dealership said they will look @ it....................2 days later they called him and said we found the problem,sir....you have a broken starter........

Some positive reinforcement never hurts!

Thanks again for your comments.

I was thinking the same thing about the mechanics, but it helps "hear" it from someone else.

I will follow-up on your suggestion.

Best regards,
