It will not start so I had battery tested and was bad so got new battery. Installed battery and registered it but will not start. I did notice there is a plug not plugged in on battery. I do not see a place for it to plug in and when I took bad battery out I did not notice the plug until the new battery. I have researched the battery but nothing shows this plug. I have included picture to show you.

That looks like some kind of service connector and may not be used. Is the security light flashing when you try to start it?

Cheers, Ken

Okay, we need to check to see if it is an ignition or fuel related issue.

Here is a guide to help us see if the ignition system is working.

We should also check the compression to make sure the engine is sound.

Please run this test and get back to us so we can keep helping you.
