Mazda Repair Questions? Ask Mechanics for Answers ASAP
Hello my name is***** am an ASE Master Technician and I am glad to help you with your question.
Check the crank sensor, this is what controls spark on this engine.
Do you have any codes?
The next step would be looking at a engine control module problem.
Do you have a wiring diagram of the engine harness?
I can send you one if you would like.
Unplug the cam sensor and see if it will spark.
There is a capacitor on the right rear of engine I would check this as well.
Check the engine fuse 15 amp, left end of dash.
This sounds like a pcm problem, I would swap out the engine computer on this.
Yes, you have to program the pcm to recognize the keys or it will not start.
