hi i hope i can help
remove the spark plug hook it back up to the wire and place the spark plug close to the engine or frame. Then turn the engine over and see if you have spark at the plug
if you have spark then put the plug back in. if you do not have spark the you will have to check the coil pack.
if you have spark, then you have to check for fuel. make sure your fuel is turned on if it is turn it off pull off the line and blow into it to make sure you have no block in the line. you should be able to blow though the tube. if that is ok then you will have to do a compression test on the cylinders.
