Timing belt ripped while driving. Got new one and began process of replacing old one. Did that, but when we put everything back together it failed to start. We checked alignment and every possible resource about alignment and it is aligned- but nothing. It’s not starting because we’re not getting sparks. New spark plugs, wires, and ignition coils. Additionally, we replaced the old camshaft position sensor, so the last thing we have on our minds in the crankshaft sensor.

Hi,

A faulty crankshaft position sensor will prevent spark. Do you have a live data scan tool? If you do, plug it in and check to see if there is an RPM when cranking it.

Here are the directions for replacement. The attached pic correlates with the directions.

Hello, thank you for the quick response. Regarding the sensor, we had actually just replaced it. Interestingly, the previous owner said he had put it in backwards (no idea how he could have done that), and it worked, up until the belt ripped. But, it could be that the new one is faulty.

Yes, it could be. I would use an OEM part. Please let us know what happens after you replace the sensor. Can you please shoot a quick video with your phone so we can see what's going on? That would be great. You can upload it here with your response. That way we can hear the engine cranking over to make sure we are not going down the wrong path.
