I did start the tread or sticky. I apologize if I've disorganized or messed up the form some how.

Any and all help is greatly appreciated. I couldn't have come this far without all of your help.

Now, on to check the engine ground.

Cheers,
William

No worries, William. I think only admins can make sticky threads so my question was really for them. You're getting good help.... good chance you'll get it sorted here.

For the future you can check the integrity of the engine ground strap from the top of the engine by measuring the resistance from the engine block anywhere to any bolt that makes good electrical contact with the chassis.
Naturally this reading should be close to zero ohms.

I was able to access the starter from under car. As shown on attached picture, remove control arm bushing and swing it down to take out the starter. I used an extremely long 3/8 extension to reach the bolt. Perhaps later I will have the time to do a diy write up.

Re: Starter Replacement DIY

Forgive me for i am just a poor girl who knows not very much about about cars. Im pretty sure my problem pertains to this thread. First off ive pretty much ruled out the bettery. On cold mornings i have a hard time getting her started. (2001 330ci) the engine turns over fine, not slow anything but wont start. Called my dad, he said to prime the fuel pump a few times before starting, and sure enough it starts up fine. She doesnt run rough at all, no check engine light, nothing. Now, on really cold mornings, below freezing, the same thing happens, except that after priming the fuel pump about 3 times, the engine starrs, sputters and dies. She will do that about three times before she starts and stays started. Then she purrs like a kitten. My dad thinks it could be moisture in the lines or fuel filter? He's unsure, and not a bimmer guy. I use top shelf, premium gas, and never let her go below a quarter tank. Only other thing is she's due for an oil change. Thanks for any feedback :o

Hey Robin, your problem is def not a starter. No big deal but to stay on topic, why dont you copy what you typed into a new thread and I and others will respond there?

How many miles? With symptoms like that (and no other details) I'd start with a fuel filter and pump. If you have more than 100k miles, I'd chalk this up to E46 maintenance.

Also a possibility is leaking injectors, depressurizing the rail overnight. But those are more the exception and not the rule. I'd start with the filter and pump.

robinsonam1984,

Per your description of your no start issue it is weather related. What testing have you done that led you to eliminate the battery? Have you tried boosting or jump starting and the car will not start?

Re: Starter Replacement DIY

The battery was new in march, or so the guy at the dealerahip said, ive cleaned all the connections, as i had problems early on with the cables being corroded.

I would not exclude the condition of the battery by what the dealership told you. You need to have the battery tested. At minimum, have a multimeter and get a voltage reading off the battery.

Another possibility is you may have a grounding issue with the cables.

Leaking injectors will have the strong smell of gas after it starts. And priming the pump three times would not be a cure for this defect.

Agree with the pump and filter.

Slow, intermittent or no starting

I had the same problem, changed out battery and starter same problem. Turns out there is a switch in the steering that was going bad. The switch connects to the key cylinder and allows voltage to run the starter. I took it off and replaced it, no issues after. BTW I took the switch apart and found corrosion on the contact points which leads me to believe were the cause of the intermittent starting problems. since i changed it out I have not had any problems, hope this helps.

Great reminder to mention that. Not uncommon.

marvel0124, can you expand or perhaps do a step-by-step fix of the switch?
