Initially, I noticed battery drains when the engine is off. I did not consider it a problem, the battery I used was old. But one Sunday after I came back with the car to the house, every attempt to turn on the engine was abortive. I moved to replace the crankshaft ignition sensor because the original sensor had issues and I was advised to change it. Now this occurred I had to replace the 2 ignition sensors but as I speak, the engine as not started.
