Is this sympton of a bad ignition switch?
I drive a 88' 325i and sometimes when I turn the key to start the car, it cranks for a few (up to around 5 seconds) before starting. For a week, it did this every time; then, all of a sudden it stopped and started up right away for a week. Now, it does this maybe once every 3-5 times. The starter checked out fine, I just replaced the alternator, and the battery is also new. I don't smell fuel so I don't think it's a leaking fuel injector or fuel pump related as when it's on, I don't have any power drops or anything like that happening.
When I was at the shop getting my alternator replaced, I was told it could possibly be an ignition switch not sending a signal to the computer to tell it to turn on. (something along those lines).
Does this seem right? If so, I'm visitng Bimmer Heaven this weekend to grab some parts so thinking about getting a used ignition switch as well since the DIY seemed fairly simple to do with basic tools.
Any ideas what else could be causing this?
Thanks in advance,
