You may just have a failing crank sensor that works intermittently. If you have a volt meter you can test it.
You'll set the meter on the AC volts setting and place your leads into the red and black wires leaving the sensor. While cranking, the voltage should be 1 to 3 volts depending on cranking speed. If you see less than 1 volt you need to replace the sensor.
If the sensor tests good I can help you to further troubleshoot.
I hope this helps. Please let me know if I can be of further assistance. Also, please leave a positive rating for my service today. Thanks, P.J.
I understand. I hope they are able to take care of you there. Let me know if not. Take care, P.J.
