Welcome to the forum, are you saying it cranks good but won't start, or it won't even crank? If your saying it won't crank, make sure the battery has a full charge and the connections are good, then check the circuits at the starter relay in the fuse box under the hood. If it cranks good but won't start, have a helper crank it, while you check for spark at the plugs. Use a gage and check fuel pressure.
