If the engine will not crank when the vehicle is parked on an incline, the transmission linkage may need adjustment. Some diagnosis is required because this may also be caused by inhibitor switch failure. The inhibitor switch tells the computer that the transmission is in "Park" or "Neutral", and allows the engine to start. If the inhibitor switch has failed, it will need to be replaced along with the "manual plate". Our technicians recommend checking with Mazda for updated parts.Google+

Mazda MPV Engine Won't Crank When Parked on an Incline
Mazda MPV Problem
Engine Affected: 2.6L 4 Cylinder
Visitor, 2003 Mazda MPV, 195,000 mi
Inhibitor switch gone bad? Can't get car in park - removed hazard fuse to get the key to come out but now turn signals won't work. Also sliding doors will not work due to sensor not recognizing the van is in the park position. Dealer says they see this All Of The TIME. Why isn't this a recall item?
