lost crank shaft position sensor

Last night I was driving my 2008 smart car and had no troubles. I went to start the car in the morning and it wouldn't start; it would crank and not even try to fire.

I did the usual troubleshooting with the fuses, fuel pressure and what not. I then crawled underneath to check out the crank shaft position sensor and noticed it wasn't there. The electrical connect was intact and nothing was broken. The bold was gone and the sensor itself was gone. The bolt hole doesn't appear to be stripped either.

I'm suspecting the sensor was stolen during the night but I'm curious if there's a chance the sensor could've fallen off last night while driving and the car would run without it once it's running? The car obviously won't start without it, but if you take off the sensor while it's running will it stay running?

As already said, it will not run without it.
Hard to believe, but somebody stole it. Even if it fell out (which it didn't) it would be hanging by the wire.

Thanks. I kind of figured it had to been stolen. I still can't believe someone would do that.

I need to get a new bolt to hold the sensor in. To me it looks like an m6 thread. Any idea on how long the bolt needs to be? I ordered the Beck Arnley 180-0403 and it should be here next week.

That is strange. I guess someone up there didn't want to wait a week for a part. Smarts are so far and few between here in Las Vegas, I have no idea where the closest smart is to me.

Got the new sensor today. Beck Arnley 180-0403. Car still doesn't start or even attempt to fire. Is this the wrong part or is there something special I need to do other than bolting it in and connecting the wire plug?

I would check to make sure your brake light switch is working by stepping on the brake pedal and seeing if the stoplights work. If they do, I would get some starting fluid and give it a quick shot at the air intake to see if the car will start briefly. If this is the case, check your fuel pump fuse to make sure it is good. Have you scanned for codes? If the two things I mentioned don't yield what your concern is, I would sure look for DTC's.

All of those are good. I'm pretty sure I can hear the fuel pump kicking in when I first turn on the key. I also have pressure when I pull the line off of the fuel rail.

The whole reason I replaced the CPS was because mine was stolen. I'm thinking I got a bad part. I've rebooted the ECU about 8 times and nothing seems to help.

Thanks for the tip about the brake lights. I didn't think to check those.

I already sent the sensor back. How would the parking brake affect it? I always start the car with the parking brake set and never have troubles. The parking brake wasn't set when I was trying today.
