Yes it was starting before. It won't start with either sensor now. Starts and cuts immediately.

Yes the wires and connectors look fine. I did get it to start after multiple attempt. Runs fine when finally started, turn it off back to square one again. Checking for spark now.

Was it flooded?If it starts you know the spark is good. So if you clear the P0340 it will reset right away?

Apparently I have an intermitted problem. Further checking I noticed the spark is leaving during initial cranking.

So the P0340 is a active code meaning when you clear it it comes right back?
