No start, no spark, no fuel pressure - cranks fine
One day car would not crank (just a single click), battery was not the cause as there was no voltage drop when cranking, changed starter and battery and car was fine after job was done - started normally and ran fine. Later on the same day, the car would not start but this time the engine would crank just fine. Scanner showed P0336 (crank sensor). Replaced crank sensor and still the same with the same code. Did continuity test of the two wires that run from the crank sensor to the PCM and wires tested perfect, neither wire was grounded. Customer had car towed to the Mazda dealer. Anybody know what is wrong?

HouseCallAuto 9/14/2010You will never in a million years believe this one. The starter I installed (aftermarket reman.) is "incompatible" with the minimum RPM requirements of Mazda. In other words, if the original Mazda branded starter cranks the engine over at lets say 240 RPM and an aftermarket starter is installed and lets say that starter cranks the engine over at 235 RPM, the PCM is programmed to ignore the crank sensor signal until the RPM is within minimum spec. Mazda installed their starter and the car is fixed. The starter I had installed had showed no sign of the cranking RPM being weak in any way. I refunded her money that I billed her. Even the customer was in shock! I could never win this one. Who buys dealer starter motors?
