Hello and welcome to Just Answer!

My name is Amedee and I can assist you with your question.

Does the engine have spark when cranking it over?

Does it run on starting fluid?

Are there any codes in the computer?

Expert:  Amedee replied 4 years ago.
Hello!

Just turn the key on and measure voltage going to all three wires (one at a time) using a voltmeter.

Also, check to see if the check engine light comes for a bulb check when you turn the key to the "on" position.
