Can a sensor act this bad? I have a Nissan Sentra 2005, and after the car becomes hot; anywhere from 15 minutes to 3 hours, I have to crank it at least twice before it starts. I have replaced the crank sensor, but no change. I replaced the cam sensor four times from different suppliers, and the car won't start hot or cold. So I put the original sensor back in, and it starts. Yet I still have the same issue for that 2 to 3 hours when it's hot


Some models will not function properly unless you use OEM. Get the DTCs and go from there. You may need to check the circuit as well.
