The coil on my 2006 Titan gets hot it gets so hot that it burns out and wreaks the coil. Can anyone help?

Is it too close to an exhaust header/manifold? Too much heat could compromise the electrical insulation of the coil, causing it to arc. Get a list of recalls for your truck in case its a design flaw. If its losing spark because of a short, you will need more than a handheld diagnostic tool to check that. Electrical bugs can be a nightmare to figure out on your own, so I don't reccomend just going through and replacing lots of parts that aren't bad anyways, I have done that before and spent a few hundred dollars on stuff that already worked.

There is something wrong if a coil is getting so hot it burns itself out. That simply should not happen. Hell a coil is just big roll of foil with an iron rod in the middle to step up 12 volts to 30,000+ volts. Sounds like a bad short to me.

Since you are in Alberta, MY PART OF THE WORLD, I am going to highly suggest you contact a dealer. Talk to Cam at Sunridge Nissan Parts in Calgary. He's the best Nissan parts guy I know and he's seen it all!
