My son recently purchased a fiat stilo 1.9 jtd dynamic 04 registration it suddenly developed a power steering fault so we changed the upper column then developed a glow plug failure so we replaced all the glow plugs. put a brand new battery on the car. now for no reason what so ever it turns over but will not start I'm totally lost on this all help or advice would be great as if this engine isn't running in the next couple of days they cannot fit the smart box and my son loses his insurance
