Read evidence and context

Explicit resolution reports before identified causes, performed actions and suggestions. Within each level, matching component labels precede direct query mentions and inherited thread context; successful versus unsuccessful discussion counts, owner confirmations and independent discussion support determine order. This is not a probability of success.

Discussions that report identifying a cause: 1

0 original-poster resolution reports. Counts can overlap; they are not unique people or a success rate.

0 discussions have direct query context; 0 report a fix in that context. Other evidence may inherit the discussion’s subject.

Reported cause
Yes, the ignition switches are known points of failure, but the likelihood of the replacement having the exact same issue is slim to none.

Coverage and how to read this overview

Counts describe captured discussions, not unique people or a diagnosis. Author identities are not reliably stored. Exact duplicate evidence is counted once across matching discussions; one discussion counts at most once per action/state. Multiple repairs reported together remain a combination. Suggestions and failed attempts do not establish a fix. Matches cover whole discussions and can include related faults, model variants and incomplete threads.

5 eligible posts · 0 unverified posts · 1 discussions match the subject in their title or opening post.

POST 1 / ORIGINAL POSTEROriginal post

I've have a 99 2.5 manual boxster that I've been fighting multiple gremlins with. I just got a new immobilizer/ecu/key from ecu Dr and now my locks seem to be working 90% better now. However after installing that new set the ignition will not turn off until I press the brake pedal. I can turn the key and take or out, but the engine will stay on until the brake pedal is touched. I replaced the ignition switch but the car still acts the same. I also can't find any information on this problem. Any help or ideas on this?

POST 2Original post

Quotes source post: 595437

I think your answer is inside your question: "...after installing that new set..." If the problem started immediately after, I would suspect the Immobilizer or the ECU. Have you tried ECU Doctors for help? What was wrong with your old Immobilizer/ECU?

POST 3Original post

Is the wiring on the ignition switch repaired or modified at all from a previous owner? Sometimes from stereo or tracker installs they can get hacked up and compromised. I'd still suspect the ignition switch. Sometimes new parts are bad.

POST 4 / ORIGINAL POSTEROriginal post

Okay thanks for the help. The old set had water damage in the immobilizer and the CLU didn't work at all. It was too damage to repair so they sent me a new matching set. I'll dive back in and check the actual ignition wiring. The car did have an aftermarket radio. ECU Doctors just told me that it's a common problem with the ignitions in these cars.

POST 5Original post

I assure you that your issue is not common. Yes, the ignition switches are known points of failure, but the likelihood of the replacement having the exact same issue is slim to none. I would keep pressing ECU Doctors for assistance. In the meantime, I will look over the wiring diagrams for you to see if I can provide any insight.
