Mazda Repair Questions? Ask Mechanics for Answers ASAP
Welcome, I'm Chris (aka Moose), my normal schedule online is around lunch and after dinner past midnight.
Did I understand correct, after the first revolution of the engine when cranking you lose spark and pulse?
If you remove the VREF wire from the PCM, then turn the key on and test the empty VREF pin, is the PCM putting out 5 volts?
Can i get the engine liter size to get those diagrams to you?
I can send diagrams here. I can not send them over a phone call.
The Brown wire pin 2H is the VREF
This is my 1st answer of what can be many. You the website and myself expect you to have a ~~~5 STAR EXCELLENT~~~ experience with my help. At the top of your screen is the rating box that you only get to use once. Please make sure to complete the mandatory rating when ready or reply and say "I am pleased with my answer". Not rating or rating 1-2 stars does not benefit you nor me in any way.
Sorry I do not have a connector pin chart with my diagrams. You can find the brown wire and confirm your at the right wire by comparing the color of the wires next to it.
What voltage are you getting from the PCM?
Sorry but I just can not figure this one out. I will remove myself from the topic so another can try.
