The E46 M3 Journal

No vacuum leaks. Burger hooked it up to a fuel gauge and figured out the no start issue. The fuel pressure stayed right where it should be. Then they found a no spark situation. They let the car sit for 15 minutes and they said that that is when the ECU automatically resets and replicated the situation again. So, he is testing the ECU just to make sure that it is the problem before I order a new one $$$$.
A new ECU will fix the no start issue but they can't guarantee the too lean/too rich codes will disappear. I figure if the ECU is causing a no spark situation at start-up it probably is doing the same thing while driving.

It's weird that it's going back and forth between rich and lean. That's the only part that has me scratching my head a little. But you said you checked cimpression and it was ok? if compression is ok it very well could be ecu issue. Burger to the rescue! Hopefully you get the issue sorted though. At least you didn't bring it to the people who worked on your e30. Haha.

Maybe... depends on the s52.
I just need to get the e30 rocking again.

Yes! Dream build! I'd love to have an e36 with an s54 or euro s50.
