Check for spark use a good plug and ground it to the block with insulated pliers.
As someone else cranks the engine watch for spark.
If no insulated pliers use a jumper cable one end on the plug the other end on a good ground.
If you have good spark I would suspect a fuel problem. Use a noid light and check for power to the injectors.
http://www.amazon.com/ Search Equus scanner I would suggest a 3160 if you can afford the price.
Post if you have spark and we can give you more help.
