No spark?

This can be because the timing belt is jumping teeth. I would remove the timing belt cover and check the condition of the belt, it sounds like it needs to be replaced, and it will create this code if the belt is off.

P0337 - Crankshaft Position Sensor "A" Circuit Low Input

Here are the timing belt marks. It will have no spark if the camshaft is not turning. Check out the images (below). Please upload pictures or videos in your response.

I'll will check that. I just put a new belt, idlers, tensioner and water pump on I followed the installation procedure and when complete, removed the spark plugs and spun the engine over to track the belt. All seemed fine. So, I put it all back together and it started right up. It ran fine for about 200 miles. Thanks Ken!

So you installed a new belt, and it fixed it?

Ken,

You suggested that it could be the timing belt broke or skipped a tooth.
The response you got is what parts were installed prior to the problem that I am having now. The problem is the initial question that I asked.

I have installed the following new parts prior to the current problem.

1. Crankshaft position sensor
(Old one was setting error code
PO337) New sensor set PO337.
after 200 miles. The code was.
cleared and didn't come back
2. Timming belt and pulleys
3. Water pump

I said I would check the cam timing belt. I have not had the chance to get to it. Thanks

Ken, I checked the timing belt, and it is good. The timing marks still all line up.
There was a post on Mon. June 28th 2010, so aboutb15 years ago.
The post was from JER680.
He describes the almost identical problem that I have now.
I am unable to read the replies and am unable to see whether his problem was resolved, and what the outcome was.
I don't know if there is any way that I can view the conversation or not.
Perhaps you can go back a view his post and find anything that might help.
I have ordered a new cam sensor, just in case.

Thanks, and I am looking forward to your reply.

This post, correct?

To confirm there is no spark correct? If so, you are on the right track with the camshaft sensor. I would turn the key on and test all fuses in the panel under the hood. This guide can help:

See if fuses # 16 and 17 have power, this means the ignition relay is working. Let me know how it goes.

Ken , Good news it starts and runs!
While waiting on the cam sensor, I had time to think about the problem with the no spark issue. It seemed and had the symptoms of a CPS failure. But I had just replaced it with new! The CPS was an OEM supplier part and was more expensive than other comparable brands. So I disregarded the idea it failed so soon. Then I went on to check wiring, fuses and security system for a inhibit signal. Everything checked out good.
So, I went to my local auto parts store and bought a generic brand CPS (Crankshaft Position Sensor) made in Taiwan.
The OEM Brand was made in China.

Installed the generic cps part, and it is running!

Thanks for your help and for getting back to me!

Glad you could get it fixed, thanks for letting us know. Please use 2CarPros anytime we are here to help.
