Hey guys new here and stumped. I have a dtt tcfi3. A couple days ago I went to start it and it turned over longer than usual before firing and through the check engine light for a second then went out. Ran the codes, had p0373 and p0374, so I replaced the ckp. Now the bike won't even start it turns over and back fires through the exhaust I put the old sensor back in and got the same thing. I pulled the plugs and they are wet I checked for spark and have it. I plugged in the original ecm and still no change. I did use engine detailer on it(which I've done a hundred times) before changing the sensor so I hit all the connections I could see with contact cleaner just in case that screwed up a connection. Any help would be greatly appreciated. Thanks

 

Never mind.. Got it. Sometimes I'm my own worst enemy

 

Well....what was it???

 

Well... while I was waiting for my sensor to show up I was cleaning the bike and found a rattle in the area of the coil so trying to find it I pulled the plug wires and swapped them when I plugged them back in. The worst part was I even swapped them and made them right once but the motor was so flooded it didn't fire so I swapped them backwards again. So... Thats what screwed me up for two nights. Your welcome you can laugh now
