New starter not working

[acvr4]

Hey guys - have a question .
Just replaced my starter with a brand new Bosch starter. It worked great.
Now a week later I drive to my girlfriends and shut the Z off and later that night nothing again.
I have power everything works but the starter .
I'm wondering if the battery could just weak enough not to start it ?
Or what would you think ?
Key triggers the locks and alarms .

Lost

Thanks any help would be appreciated

Worn out contacts in the ignition switch.

Have a load test done on the battery to find if it's the culprit. A number of auto parts stores will test for free...or get yourself a load tester....

Maybe a flaky clutch switch? Code it out. If that doesn't work, use a volt meter to determine if voltage is making it the starter when you turn the key, it not, the problem is upstream from the starter.

Did a load test on my battery before I replaced the starter - it tested good and I tested it a few times.
Brought a jumper pac to verify it wasn't the ground and it still no go.

Adjust your clutch stop down. If it too high it prevents the clutch being depressed enough which prevents a start.

I would think a bad starter, just because it worked great at 1st unfortunately doesn't mean anything. Might be a relay or solenoid on the starter. Did a connection on the start come loose?

My money is on the clutch stop also. They can be temperamental to temp changes if set too high.

Actually experienced this myself recently.

So it was crazy - my power locks don't want to disengage the doors (think I'll have to open them up and clean years of build up out) but I used the key in the pouring rain that evening.
Something didn't feel right when I turned it.
After checking all the fuses in the lower two rows ( just had a fuse tester and it was difficult to get to the upper ones)
I had a friend tell me to check the immobilizer fuse- I had checked the low amperage ones but tried it again on a better day on the upper 40a ones - well that was it it had blown the 40a immobilizer fuse .
Replaced it and I've been good to go .
Thanks for the suggestions .

Interesting. Thanks for updating us and glad you got it fixed.

Your problem was similar ????, My Z4 E85 sometime doesn´t wants to start, I have electric power, the key is working fine and charged but when I open the switch and try to start the car nothing happens!!! only after several times closing and open the switch then start.

I think could be the Ignition Switch Starter but I see you have a similar problem, so what do u think ?

The simplest things and looking at your location, a prime suspect.

My car is automatic, so no clutch problems.

A question the ignition switch starter is different than the starter ?

The ignition switch is where you insert the key.
The starter is an electric motor that spins the engine to start it.
It may be best to have a professional diagnose the problem.

This is my problem! =(

And both could make the same problem of do nothing after turning the switch on with the key ?

What's up with that shifter, maybe that's your problem
No comments on the rest of the interior...

[mariocaz]

The shifter ? I don´t think so because is on parking also in neutral and the same.

I checked the battery and the terminals are tight too.

[Z_Pilot]

WOW, have not had this exact issue. Good info for future endeavors. Thanks all.

I had the same problem. Battery fine, terminals tight, all lights (and stereo) worked fine - but no crank.

IGNITION SWITCH.

Easily replaced - just remove the cover from the bottom of the steering column and the switch is right there.

WOW, really thank you so much for your answer bro!!!!

I already bought it and I will change it immediately arrive with me.

Do u bought one at ebay or the OEM ?

I bought this one......

[Roadroach]

That looks like the correct part. I bought mine at the local AutoZone (that switch is common to LOTS of BMW's and pretty easy to find in stock).

I'm sometimes a little leary of buying car components off of Ebay but from the photo, that one at least has the correct BMW part number on the side of the switch. Good luck!
