Hello,
Perhaps this one may be a toughie, perhaps not... I will try to describe it best I can...
When it started getting colder a couple weeks ago the 740 suddenly stopped starting... When I turned the key, I could hear the starter begin to turn the engine (perhaps half an engine revolution, 1/2 second), the normal "ker chunk" sound of the starter turning the engine. Thought it was bad battery cause of changing weather... (strangely I was able to jump the car a couple times.) New battery, same thing. Thought it was the starter... got a new starter... same thing. Once every 12-15 times it will turn the engine over and start perfectly. We connected the starter directly to the battery (with the key turned on) and "presto" starts up. There are 3 wires coming off the starter. One is a green, blue striped wire, that has a very small connection on the front of the starter. If we short this and the + connection to the battery it starts every time. Something appears to be limiting current in this circuit. Could it be the ignition module?
I am having these horrible dreams of it being some unsolvable electric problem that no one can trace down. Its not the transmission lock switch (since it begins to turn over in N and P, but not R,D,1,2). It just seems that somehow it isn't able to pull the current through, yet it doesn't seem to be a computer problem or anything because it "begins" to start. (whereas I would picture a more probable computer problem not allowing it to even turn over). Anyone have any ideas? I had pictures of this car lasting many more years!
