You must first check for spark at spark plugs and check to see if you have fuel pressure. When you turn the key to the on position without cranking the engine over can you hear the fuel pump run in the tank for 5 seconds?

I can hear the fuel pump pressurize and I took one of the spark wires and put a screw driver in near the spark plug and there is no spark. Just wondering what I would have to replace? It is up in the mountains right now trying to get it home.

Well the most common problem for no spark is the crankshaft postion sensor. If I was going to take a guess, id replace that
