I can't get my 325e to start. Everything seems to be in working order because the night it wouldn't start, I was able to roll-start it and drive home. On another occasion it roll-started again. However, I'm not getting any spark when turning the engine over. The engine turns, and I have electric power. So I checked the ignition coil and that seemed ok. I've heard that my problem could be due to the main engine relay being bad or the two reference sensors on the trans. bell housing not reading. How do I test the reference sensors?

Well, I officially don't know what to do. I donít have spark coming from my ignition coil, my main engine relay is closing with the key turned, and as far as I know both of the reference sensors on the bell housing are good (I replaced them with junkyard ones). I also tried replacing the ignition coil and ECU with junkyard ones. So what else could it be?

Hello everyone! I'm new here and I, forgetfully, did not introduce myself.

But back to my non-operational car. While away at school, my dad was able to establish that a piece off my clutch/throw-out bearing broke off, and after tumbling around my flywheel, knocked off the pin for reading TDC. I was wondering if the pin itself can be replaced or do you think Iíll need to get a new flywheel. Thanks.

You sure you're getting fuel? Have you exhonorated the fuel pump?

I was getting fuel. It turns out that if that pin isn't present, then the reference sensor canít read the piston position. Because the ECU canít read this sensor, it wonít send spark. I think Iím going to have to end up buying a new flywheel and possibly some transmission partsÖbummer.

Also, I was wondering if all 84-87 flywheels are the same (i.e. the pin on the flywheel is on the same spot).

-Thanks

Hello .... I am basicly having the same problem. I just purchased a 1984 325e from a charity auction here in Chicago. When the car came in , it was running and I drove it. From the time I drove it , till the time I picked it up...It stopped. I have replaced the plugs and wires in it and the coil seems to be fairly new. I am not that mechanicly inclined here ....so any help would be super appreciated......Please send help responses here or to my email..abruzzi60103@comcast.net......PLEASE HELP !!

If you have an eta, then you should have a dual mass flywheel. There are two types of dual mass flywheels - one is spring loaded and the other is not.

Check out the following for more info - http://www.e30tech.com/forum/viewtopic.php?t=4282

I ended up not having to replace the flywheel. I'm having a new sensor pin put back on it. But I'm still going to have to fix the clutch will will run me some money.

abruzzi60103....
What are some other symptoms of the car? What's the car doing when you turn the key...is it turning over or is it not making any sound? I'm not an expert tech but I'll lend any knowledge I have.

The car basicly cranks and sounds like it wants to turn over. I guess for a lack of any better word to use , it makes the typical wa wa wa noise. I had recieved an email from someone suggesting that I try replacing the " pick-up coil " or the distributor. There is def. fuel running to the engine , so it is a spark issue. Are you familiar with what a " pick-up coil " is ????? ghead

I'm not exactly sure what a pickup coil is but I would definitely make sure that you donít have a spark. Pull a plug out then connect it back to the wire and with it out and in a secure place away from anything important, give it a turn to see if youíre getting a spark (itís a lot easier to see this at night time or at least somewhere dark). Also try checking out the ignition coil. If you have a multimeter, read the resistances between the positive and negative posts. I believe theyíre numbered 1 and 15 (theyíre the two smaller ones without the wire going to the distributor coming off). If I remember correctly, you should be getting resistances no higher than 0.5 Ohms. I got something like 0.9 but apparently thatís okÖas long as itís not too high. Then check the resistance across the #15 and the large post that has the distributor wire coming from it. This resistance should not exceed 5000 Ohms. If you can get your hands on a Bentley book, youíd really benefit. Get back at us on what you find.

what year is your car, if its got a disributer, then just replace the top of it, there is a rotating piece of metal in there that wears down over time, and it controlls the spark, basicly spins arround and ther plugs plug into certain possitions and when the metal touches that spot it sends a spark to that plug, and if its worn down no spark! and see if you can get a nice aftermarket one like excell or somthing like that cause it would be cheaper i would imagine then a bmw one and it would be better, but if not just get a bmw one.
