BMW Questions? Ask a BMW Repair Expert for Answers.
Welcome, I'm Chris (aka Moose) I prefer to work when others don't, I am here around lunch and after dinner till after midnight.
Have you verified good compression and ignition spark?
Will it start briefly on starting fluid?
So far I believe you may have sucked up the junk in the bottom of the tank and clogged your fuel injector up so that they can no longer spray fuel.
This is my 1st answer, but does not have to be my only answer. You the website and myself expect you to have a ~~~5 STAR EXCELLENT~~~ experience with my help. Please let me know if you are pleased by selecting a star rating above or by replying and saying your pleased. Not rating or rating 1-2 stars does not benefit you nor me in any way. Follow up and reply as often and when needed, there is no extra charge to do so.
I did misunderstand.
When you jump the pump manually will the car then start?
Here is a wire diagram for the engine controls.
Since it will run on starting fluid that confirms spark and compression is good. Since it will not run with the fuel pump jumped, this leaves the fuel injectors not pulsing as one of the concerns. Are the injectors powered on the red/white wire wit the key on? Is fuse 17 10 amp powered with the key on?
Do a continuous spray of starting fluid into the open throttle body to see if it will start even if briefly.
It seems you would like to get back on the waiting list to see if another can help. I am going to opt out now and remove myself from this discussion. Best if luck
Hi there. Different expert here.
That sounds like your EWS anti-theft immobilizer system has been activated and is preventing fuel pump and ignition system operation. Try arming and disarming the system as you normally would and see what happens.
EWS-II will only disable ignition signal and fuel supply while EWS-III will disable starter engagement as well. There are inexpensive tools out there that allow for temporary EWS by-pass. Click here to see example. Otherwise, you would need OSS or equivalent diagnostic tools to find out what is preventing the DME from energizing ignition and fuel systems.
2000 was a transition year, but based on the symptoms you describe I'd say you have the EWS-II.
I'm sure that other experienced BMW techs will also tell you that, as these vehicles get older, the anti-theft systems can go bad on their own for no apparent reason.
I do wish there was a work around that I could share with you. As it is, I don't know of any way to diagnose this type of issue that doesn't involve using a capable scan tool and perhaps even a scope.
It seems you're reading something I haven't posted - what I did post was "I do wish there was a work around that I could share with you. As it is, I don't know of any way to diagnose this type of issue that doesn't involve using a capable scan tool and perhaps even a scope."
As is, it looks like I won't be able to help you; so I'll opt out of the chat to let others try. Please do not rate or reply until another expert responds or the site will cycle this back to me.
Reading your last post I get the idea that you think I'm holding back and not sharing with you some sort of procedure for which no specialized diagnostic equipment is needed; that is simply not true. As hundreds of customers can attest, my only goal is to help people who need the kind of technical assistance I can provide. I'm really sorry you got the wrong impression of what an expert on this site can and cannot do.
Now, as I opt out once again, please refrain from replying until another expert responds or the site will automatically cycle this chat back to me.
