If it's the run position, it will likely be the fuel pump cycling (sounds like a motor whirring).

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.

POST 1 / ORIGINAL POSTEROriginal post

Eventually it does, after a time or two. Maybe this is from not having the brake pedal depressed? I can kind of hear a far off starter turning, but only barely...then after turning the key left and right again, it starts. Anything to be concerned about? Thanks!

POST 2Original post

Quotes source post: 13670453

Anything to be concerned about? Well, yes. You asked about it so you are obviously concerned at some level. There's no shame in that. Frankly, I'm always concerned about unreliable/inconsistent starting behavior with my cars. When I turn that key to start I want the engine to start and of course run and continue to run until I turn it off. Every time. No exceptions. Don't think you have to have the brake pedal depressed to start the engine just the clutch pedal if the car is equipped with a manual transmission. With a Tip the transmission gear selector lever has to be in Park or maybe Neutral. Starter shouldn't turn until it is fully engaged with the flywheel ring gear. When you turn the key to start this should energize a solenoid which shoves/slides the starter pinion gear outwards and this engages the flywheel ring gear teeth. At this time a circuit is closed which then energizes the starter and it should run and spin up the engine. When you release the key from the start position the solenoid is powered down and this lets a spring retract the pinion gear which concurrently cuts power to the starter motor. I'm leaving out some security stuff of course the query for the key's RFID and such. If I had to make a guess I'd guess the ignition switch is suspect. But the electrical cabling/connections between the battery, alternator, starter, and all grounds are suspect as well. Probably a good idea to carefully check all these before you throw parts at the behavior.

POST 4Original post

Sounds like the starter switch to me, if I had to guess. Recently went through this on mine, easy DIY.

POST 5Original post

Quotes source post: 13671959

I'm also having this from time to time. Do you mean the switch where the key goes? And if so, how does that affect the key? Need to replace that as well?

POST 6Original post

Quotes source post: 13672154

Easy DIY. Just replace switch at back. Regarding start up procedure, you need to fully depress clutch pedal not brake on my car? http://www.pelicanparts.com/techarti...ering_Lock.htm

POST 7Original post

Mr. Clam, a better description of the ghostly sound would help; a sound clip would help even more. Re: being concerned - if the my car was not starting reliably, I would worry about my wife winding up stuck somewhere with a car that won't start...

POST 8Original post

That's why I love this place. So much good info.

POST 9Original post

Quotes source post: 13672427

Re: your question about the ignition switch - no, it does not affect the key. The electrical portion of the switch is what needs replacing.

POST 10Original post

Just to clarify, "starter switch" as used above is referring to something that everyone else calls the "ignition switch". Just do a search on it - there are a ton of threads on it in here. Buy the ~$27 switch, it's worth the extra money over the $9 part. And Schnell is correct - you need to fix it right away as it will strand you, and at the worst time & place possible. The good news is that it is a cheap, quick & easy DIY. http://www.warehouse33auto.com/parts...10/14/0/4516/0 (use promo code RENNLIST to save 10% by the way) And if you get in a jam, find the nearest NAPA parts store where they will keep these parts in stock, the cheap model that is, for about $12. But if you have a few days, better to order the more expensive one. If you buy the cheap one, better to just buy 2 and keep the spare in the glove box/door pocket as the cheap one may only last a few months.

POST 11Original post

Good point about "starter switch" - man do I feel goofy now.

POST 12Original post

IMO, could be the starter motor is turning but the bendix is not engaging with flywheel. Ghost like sounds

POST 13Original post

Could also be that the starter bolts are loose and it's not reliably engaging...you can interpret "ghost-like sounds" any number of ways.

POST 14Original post

There is nothing easy about installing the ignition switch in a 996. Unless you are 4'3"...and a contortionist...

POST 15 / ORIGINAL POSTEROriginal post

Thanks. The ghost sound is like starter lite, very faint sound of the starter. It is very intermittent. Thanks you guys are amazing.

POST 16Original post

Mine had similar symptoms back in the spring. Does the ghost sound start when the key is in the "run" position or only if you turn it all the way to "start"? If it's the run position, it will likely be the fuel pump cycling (sounds like a motor whirring). Mine was this infamous starter switch that others have mentioned. My bet is it's your issue too. A bit frustrating the change first time around, but not highly technical. Removing the left vent in dash made it much easier for me as I could see what I was doing without being upside down under the dash. I don't have all the links handy, but there is tons of info and tips on replacing this. And do yourself a favour and replace the tiny grub screws with a normal screw and then the job becomes tool-less next time.

POST 17Original post

My noise is definitely the fuel pump. Has that classic pump sound. After 2 or 3 tries, the engine turns over. This morning it just started first try. Made an appointment with the dealer to replace the switch. While I admire you do-it-yourself guys, I almost always get in trouble when I try these things myself. This way the work is guaranteed. Same idea with plumbing in the house LOL!

POST 18 / ORIGINAL POSTEROriginal post

Thanks. I'm gonna take my car in to get this replaced after I order the part. I am confused about the "Only for Models with Lock Assembly # 996 347 017 " Which one should I order for my 2001 C4? Thanks!
