1994 Eagle Vision Spark plug and gas flow

Hey guys! Just the other day our car started having difficulties staring. Around two days later we tried it out and it stared fine however on our way home the car completely shut off and stalled. We got the car home by a tow truck and have had a family mechanic look at it. The cars has no gas flow when we attempt to start it and the spark plug we pulled has no spark. Is there a certain sensor that controls this or is it run by the cars computer? and any advice on what has gone wrong?

Thanks for listening, McCandless Family.
