97 1.9 Z3 Cranks, but no start

[Cardriver333]

I compared everything and it confirmed the set i put together all matches. The only thing is the general control module's number isn't included on realoem, but every one i find on ebay matches its number so i think the real oem one is decoded and the ebay one's aren't so i think its good. The set I bought seems to all be compatible, I just don't know if it comes with a transmitter/ receiver module and I don't know if it matters.

I got my new wiring harness, EWSII, ignition, DME, and key and put everything on as best i could. I'm pretty sure everything is in it's place. I sprayed starter fluid in the air intake and turned the key. It seemed like it was igniting the fluid, but wouldn't run and I thought that it might be the fuel pump now because i dont hear it prime when i turn the key. The next day I was unable to get the same result of igniting the starter fluid so i checked to see if the spark plugs were sparking and they weren't. So does anyone have any idea on what the issue is? Another thing to note is that before i replaced the ignition and EWSII I think the alarm would be going off with the key out of the ignition, but it doesn't anymore.

There's also a broken camshaft position sensor in the box of extra parts, i didn't think to check the one that's on the car yet, but when I plugged everything in it seemed like everything was in good condition and went where it belongs.

EDITED IN DME

Its could be that the replaced EWS module hasn't been synced to the DME, do you have any codes when its scanned?
Here is a link to syncing the units using INPA this needs to be done in order for the units to recognize each other and the key identity thats being used in order to allow ignition to take place.

I forgot to mention that the EWSII, key, ignition, and DME i put in came from the same car. Would I still need to sync it?

Also i have a Bluetooth obd2 for my phone that is supposed to read codes, but I don't have much experience with it. Ill have to get the old style to check, but when im not working on the car i leave the battery unplugged. Wouldn't that reset the codes?

 

[colb]

I would say yes it needs syncing, some of the info contained in the EWS, and DME is also stored in the light switch unit, its held there as a backup should the other two modules fail. As far as I am aware once the EWS and DME are synced the light unit takes the update as well. Nothing to loose in doing the sync using INPA to see if that gives you back the sparks to start.
I do note that you have an early car with EWS2 it should be ok using INPA but often early cars need a real serial port on the laptop in order to communiicate they dont like a usb connection on the laptop same for some of the handheld scanners.
Disconnecting the battery will not reset any codes.

Ok, I'm ready to do exactly what you tell me.

Is this the cable that i need? I read that some require the switch on it and i assume the one with the switch is compatible with all models? Should i also get this 20 pin adapter although my car has an obdII port?

[colb]

Yes that's the cable with software you need the 20 pin to 16 pin cable changer as well the round socket will read all modules the 16 pin socket only reads engine and transmission modules. All this is on ebay as well as amazon

 

[Cardriver333]

I got the 2 cables a laptop and downloaded mikes easy bmw tools that included inpa and some others. I'm pretty sure i installed everything right, but when i open inpa sometimes it seems like it doesn't have any info from the cable. It either doesn't say anything about the battery/ignition or says the battery is on whether or not it is and the ignition on/off dot will toggle back and forth like 5x per second with battery connected or say that ignition is off, but battery is on when the battery is disconnected. I was still able to navigate to read the error code screen and this is what i saw.

You are going to need Google Translate on your phone to turn the German into English.

108, Battery Voltage, fault not currently present.

Where there any code in the EWS?

I haven't checked EWS yet, I'm still learning how to use this and wanted to make sure I'm connecting it right. I'll check today

 

[Cardriver333]

Ok i checked the ews and got these codes.

255 reset general
Static error

15 power on reset
Static error

1 wrong password at key number 0
Sporadic error

17 wrong password at key number 1
Sporadic error

I think you've found your problem then. It's not reading the code from the key?

Tony.

Do you know how i could program it to read the code from the key?

 

[NZ00Z3]

Well done on getting the codes.

Clear the codes and try each key. Check the codes to confirm that the keys are not being read.

Also, have a look through all the EWS pages. It's been a while since I've looked inside an EWS, but there should be a page that gives you some black/white dots to show you the status of the EWS with keys and drive away protection etc.

With INPA, you can go most places with out worrying about damaging anything. The only place to be real careful is the "Activation" pages.

Keys can be coded to the car, but first, lets see where the problem really is.

Sorry I don't. But I think @NZ00Z3 or Rob @mrscalex will be able.

Ok, I cleared the codes and tried starting it and it didn't register any new codes yet. I found some of the lack dot pages you talked about, but I don't know exactly what to look for. This one page says key 0 04 activated and already used
Key 1 0a activated and already used
Key 2 04 activated and already used
Key 3 04 activated and already used

 

[Cardriver333]

I gave it some time and tried starting a couple times and turned the key in the ignition quickly about 10 times because I've heard that programs some key and figured why not and it gave me these codes on the ews.

255 Reset general
Error frequency 1
Static error

15 power on reset

Static error

I checked the rpm as i cranked the engine and no rpms but you can hear the starter like normal. I did notice that the throttle potentiometer does increase if i push the gas pedal though.

 

[Cardriver333]

WE DID IT! It was ultimately the crankshaft position sensor. I just swapped it out and the car started right up.

 

[NZ00Z3]

Excellent news. Well done.

How did you come to replacing the crankshaft sensor?

I also asked the guys at bimmerforums and someone suggested that.
