Hello and welcome to JustAnswer!

There are many thing that can prevent an engine from starting such as a bad cam or crank sensor, fuel pump, or the engine controller itself. . If the engine does crank but doesn't start then I wouldn't initially suspect a security issue.

What are you seeing/hearing that leads you to believe the problem is security related?
