Gurus,
On my last trip I stopped at a parking space and turned the key off. Guess what....the engine kept on running. Hmmm. I took key out of switch and then put it back in. I turned to the right (accessory) and noticed that the dash lights came on. That told me that the switch is probably ok.
At this point, I assumed that there was a stuck relay in the panel below the passenger feet. I looked and found a likely candidate. (DDEC IGN ST) . When I pulled the relay, the engine died. Success!
I then plugged the relay back in and tried to start the engine with the key. No dice. At this point, the engine was off and would not start with the key.
I called a guru and ran the scenario past him. He asked me if I had started the engine with the remote switch which is located in the cabinet on passenger side in the rear-most compartment. I had not even thought about the rear switch. Since the key was not working, I started the engine using the remote switch and drove home. Of course the key did not turn off the engine...I had to use the remote switch to turn the engine off as well.
Today, I tried to install a new relay in the DDEC IGN ST socket. No joy. I could hear a relay click whenever I tried to start with the key. That relay turns out to be IGN ST. I replaced that relay as well and now everything works. Turns out the IGN ST relay has some burned looking spots on it.
I could not find exact matches for the relays that I had, but they are extremely generic. I bought these relays from amazon.
Lessons Learned: 1) The key controls relays located under the passenger's feet. 2) If your engine does not turn off....0) Remember CTD...Check the Transmission Dummy. (The engine will not stop while the transmission is in gear) Next, think about if you started it with the remote start. 3) The third step is to pull and replace these two relays (DDEC IGN ST and IGN ST). 4) Think ahead and make sure you have a few of these relays on hand. (I didn't but do now)
Cheers,
bill
