Turn the Key, Nothing...

[JoeMadoo]

Hello. I recently did an engine tranny (automatic) swap from an 87 528e to an 86 325es. When I turn the key, absolutely nothing happenes. I have radio, headlights, all that stuff. The Neutral Safety Switch from the 5 series has a total of 10 wires (9 + 1 extra one), and the one from the 3er has 5 wires. I kept the shifter from the 5 series because it felt so much nicer ( It has the linkage instead of the bar). But even when i jumper the green/black and blue/white wires it still wont start.

You hear any noise at all? Like maybe a relay not making toal connection, or just total silence?

[JoeMadoo]

Just silence.

Do you have power to the ignition switch? If you do, then the problem is a little beyond me, but good luck. If you have power at the switch, check your starter relay, and also the starter solenoid.

How do i check to see if I have power to the igntion?

[german-speed-demon]

If I remeber correctly, the 3er's switch operates a rod at the base of the column, there' should be a small detent at the base, with an electrical connection. (I think) If that's the setup, then you shoud be able to test there.

Well i figured it out. It was one of the brand new fuses i bought (#9) was broken. I guess thats the one that makes your car start. Anyway it startes now, but it sounds really "airy" if that makes sense.

Vaccuum leak somewhere, man. Vaccuum leak.
