1997 Eagle Talon car won't start

1997 Eagle Talon

dad is helping someone with their car, so I didn't have all the above details they asked for. He did say it is a 2-0, cubic inch engine.
The story is that they drove it, parked it, and then it would not start again. The starter rolls it over good but won't start the car. Dash board guage says fuel all the time, no check engine light.
They put a cam sensor and a crank sensor in, but still no spark and no fuel coming to the engine.
They just don't know what to do with it. I hope you can help. Thanks.
