The engine shut off while driving. Showed cam and crank sensor position codes. Changed both. Engine cranks but won't start. The crank is fast whirring sound. Thinking either timing belt or flex plate. Noticing fluid at bottom of transmission dipstick and all around. Engine light on. Flashes a few times. Still showing P0340 code.

Hi,

Is it possible for you to record it cranking and upload it for me to hear? My biggest concern is if it is the belt, this is an interference engine that will likely have internal damage as a result. Since you got codes for both the cam and crank sensors, you may be correct with your theory.

If I can hear the engine cranking, I can usually tell if it's a belt/timing issue.

Let me know.

Hi,

I listened to the video. You have no compression. It seems the timing belt has either jumped or has broken. This is a concern because, as mentioned, this is an interference engine.

At this point, confirmation is needed. You will need to remove the timing belt covers to inspect the belt.

I attached a pic below showing the belt and routing of the belt. To remove the entire cover will require a good bit of work. Instead of everything, see if you can remove a few bolts on the cover and open it to see if the belt is still in one piece.

Or remove one of the valve covers and see if the camshafts turn when the engine is cranked. The remaining pics are the directions for the removal and replacement of the cover. We are focused on removal at this time only. Based on findings, it will be your call on how to proceed.

Let me know what I can do to help or if you have other questions.

Take care,

Joe
