Don't know if troll or srs

Anyways, I would swap your main relay to be safe and is your battery in the trunk? If it is, check the lug that the DME is connected in the engine bay where the battery would be if it was there (passenger side against the firewall closest to the fender). I had no power at my coil and turned out the DME wasn't even hooked up to the power terminal in said location.

Bogging down below 2500 rpm could be fuel related which is another topic of discussion.
First focus on spark then fuel IMO since fuel is currently present while spark isn't.

Did you do anything to your car before you ran into this problem? Or did it just pop up out of nowhere?

Well you have to buy her nice things if there's no spark in your relationship. hehehe

I have no help to give, because I know nothing about cars, but I can't wait to hear WTH caused this. Always good to read these things for further knowledge.

Good luck and I hope you get this fixed.

hell ya bro good lookin out i'll check that out first chance i get..................o and any one in the porland area im putting together a big bimmer bbq this summer at blue lake park ill post info in the gathering section when we get the details worked out just keep an eye out for a blue lake bimmer meet post in the future

Look on the bottom of the transmission, driver's side. You will see two sensors. Pull the lower one out, if it looks like it's been hit by a piece of metal, odds are your cps lug came off. You can confirm it by looking in the hole while someone turns the engine (22mm bolt on the fan)
I'll post exactly what I did to fix mine later today.

ya its an eta.. but my belt didnt break at all and all my valves are fine i bought a valve cover gasket and pulled the valve cover and looked just to be sure and everything looks to be in order and i forgot to mention i also changed my ignition coil so i have changed everything i can think of that has to do with spark and still none is there a way to test the cps i mean im really at a loss hear i cant get any spark at all the car is turning over just fine i have plenty of juice plenty of feul and my maf is fine i hooked it up to my bros eta and it worked i just cant think of anything else if there is any one in the portland area that can come get my shit running i dont have much cash at the moment but i have been a tattoo artist for 15 years and have a pretty extensive portfolio i will gladly trade work for work on the spot come fix my shit and ill ink ya up after ....you can look at my work on google drive.com/onthefly36@gmail.com hit me up if you can come help or even if you just have some more helpfule hints thanx for everything guys

[Rigmaster]

WTF?

If the timing belt broke while cranking it, you've got some bent valves for sure. Don't believe me? Do a compression test and see.


All the spark in the world isn't gonna help if you've got bent valves.

[amcink]

CPS will fixed it

[P.Muck]

If this is on your ETA, it could be the lug on the flywheel or one of the sensors. I went through this last summer.
I ended up drilling a 2'' hole in the bottom of my bellhousing and welding a new lug on, then patched it up.
It pretty much sucked, but it forced me to change the cap, rotors,coil, and buy a spare DME for future troubleshooting.
Plus, I know all about the motronics for ETAs now...

New cap rotor plugs wires timing belt tentioner dme and still no spark im getting mad ......i know its gotta be somthing so simpl that im just over looking

First change your timing belt/tensioner/and probably water pump while you're in there. Then swap your DME and go from there.
