I just bought a 2000 BMW 528i with 95,000 miles on it. The lady that had it said it was running great when she parked it and it sat for 6 months. When she tried to start it the battery was bad and she replaced it. Now will crank but no start. I pulled the plugs and put a 1/2 oz of oil in each cylinder thinking it may be a compression issue. After cleaning the plug it seams to want to fire but won't start. It's getting fuel.
