It could be the coil, charge coil under the flywheel or the MPEM (black box). These are difficult to diagnose without a manual. The only thing you can do is pull the electrical box and check all the connections, there are many. Try to see if it's something simple. If not you may have to take it to a dealer. Make sure the plug that goes into the front of the engine is in there tight. I have seen these pull out several times.
