Hello all. Mine is a '98 355F1, 41k miles, pretty much fully sorted mechanically. Went to start it the other day, and had a funny experience. When turning the key to the "start" position, nothing happened. Thought maybe I didn't turn it all the way, so reflexively turned back to the "on" position. As I did this, and without turning to the "start" position, the starter began to turn. Briefly the car fired up, but I was very uncomfortable with what happened, since I did NOT turn to the start position. So I turned the key to "off", just in case the starter was trying to turn still (while the motor was running). To my surprise, the starter continued to spin even with the key in the "off" position! Even when I pulled the key out, starter still spinning. I had to raise the front trunk lid, take off the battery disconnect cover, and turn off the battery in order to get the starter to stop. Very stressing. So, today I had time to take out the key/lock assembly. Expected to find shorted wires, but it all looks good. No signs of cut/frayed/burnt wires. PITA to get out, by the way. Looking around on the net to check prices, and it's a "contact us" deal everywhere except Europe. Additionally, no such thing as just an ignition switch for sale, must buy new door lock tumblers and 2 new keys as a set with the ignition switch. I'm sure this isn't cheap, hence the "contact us" bit. So, before I go spend yet more big money on this car (and endure the wrath of my wife), is there any ideas out there which may save my ignition switch? Thanks for any tips! John
Start at the starter. Maybe a fried solenoid. Ignition switches rarely fail, starters usually go first. Easy to remove and test.
The run, start and accessory power functions of an ignition switch are all separate circuits. I would say the chances of the switch being your problem is unlikely. Do you have an alarm system? Many of those demote the iggy switch to a simple relay and control the start and run functions internally. Start with the solenoid as Mr. Plugs suggested then look for the alarm interface (if you have one).
It's just the stock alarm system. The initial delay in the starter turning is what makes me think the switch is the culprit. Expensive theory to test though.
Buy a remote starter switch at Harbor Freight <$10. Hook it to the battery and to the small slip-on terminal on your starter solenoid, key off. That will isolate the starter. Press the button and see what happens.
