Long crank but starts for a few seconds then dies. It has 3 codes 2 for a can sensor code and 1 for a crank sensor code. I replaced the crank sensor with an oem but stilll does the same thing, starts and dies. I can see the voltage change from 5v to 0v when I pass a ratchet by the sensor on my multimeter. So i think that is working correctly both sensors.
It would be helpful to know which 3 codes, specifically, you are getting.
