Welcome,
I will be happy to assist you. If you have a question or need clarification please post back at any time.
Is this the three cylinder engine?
Your engine has a battery operated ignition system. Make sure the battery is fully charged and all connections are tight. Check for 12 volts at the starter solenoid and the red terminal on the switchbox. When you turn the key to run you should also have 12 volts on the white wire.
If you don't have the proper voltage the ignition system won't work.
Check these and post back what you find.
