    Cleaned sensor still no start or signal from the crank sensor. So as assuming its the crank sensor itself that went bad. I would assume they can and do go bad as i had figured as much it was sensor as thats what the scan tool tells me

    Your post only said that you inspected the wiring and plug that's why I wanted to check

    Keep in mind when you replace the sensor you need to be ABSOLUTELY SURE it's in the EXACT RIGHT LOCATION or you may run too much or too little timing.

    Issue solved. I still need to do tdc then count 20 teeth..but old sensor was at a spot i could line the new sensor up at basically same spot. The car starts and has full rpm now. Once tge peg comes ill redo the crank position sensor specs..
    Thank you all for your advice

    Crank position sensor issue. Cars fixed and goes full rpm now
