Hi,
Did the no start begin when the lights were lost? Also, if the starter engages and it won't start, in most cases, it is either a fuel or ignition-related problem. Have you checked for either?
Do me a favor. See if it will start with starting fluid. If it does and then stalls, we know it is fuel related. If there is no change, it's likely ignition related. In that case, I need you to check for spark to the plugs. Here is a link that explains how it's done:

Also, here is a link that explains the most common causes of a crank no start condition. Take a look through it and see if anything helps.

Let me know what you find or if you have other questions.
Take care,
Joe
