I'm new to the forum, also in KC area, and trying to help my son, Jason, getting a 94 530i running.
At first, thought he had registered since he has 5 BMW's at this time, but realized that the vehicles were not the same.
I am looking to find someone in the area with a similar BMW, at least the electronics, so I can possibly read some test values from their car and compare against his. After replacing the engine, the replacement from a salvage yard will not fire up and run. Appears the injection timing is "off" by some significant amount WRT the crank and cam positioning, and am presently "stumped". The mechanical "hard parts" are aligned OK, so it is apparently something in the Motronics. Even used a different ECM/DME, but did not correct the problem.
Have a great day, Easter and spring in KC. Best wishes with your projects.
