no crank. no start
Hello.
I have a 2008 z4 3.0i. I went to start it a couple days ago and ran into trouble. I turned the key and it tried to start (sluggish and then stopped). I turned the key off and then tried again. This time, absolutely nothing. I figured it was the battery, but I had it tested and charged (its a new battery and contacts are clean). The battery is good. Next I though it was the starter. I went through the pain and removed it. Took it to have it tested. Starter is good. Next I thought it was clutch switch, but I can hear it clicking as the circuit is completed. I know it's not the engine or alternator because I was able to bump start the car drive. The only item left I can think of is the power distribution module (basically where the relay is). Anyone have any suggestions?

It could be the ignition switch.

Nope. Wasn't the ignition switch. Replaced it 2 days ago. Went to get in today and nothing. Wouldn't start. Just like before. No noise at all

Did you actually change the starter?

No. I removed it and took it to autozone where they tested it. They said it passed, so I put it back in

A jump pack directly to the back of the starter will rule it out.

So I pulled off the starter solenoid terminal connector and took some readings when the key is in the CRANK position. From battery + to the solenoid connector, I get 0 volts
From the battery - to solenoid connector, I get 12.3 volts
I'm no electrical engineer, but I interpret that as making sense (if my starter is bad). If the solenoid terminal is getting 12 volts when key is in the crank position, that means it MUST be a starter issue.... right? I'm just confused as to why autozone said the starter was good if it really isn't.

This won't cost you anything to try and all you need is a long jumper cable.

I just went out there and tried. Grounded the engine to the battery with a jumper cable. Still nothing. Didn't think it was the issue (I see the engine ground strap an it's still solid)

Like I said, it won't cost you anything and you can now rule it out as the problem. Pull your starter (your more than likely have to do it anyway) and have it tested again at one or two other autozone store's.
