what does "no start" mean?
turn the key to the start position: and nothing happens?
: and there is a big click but the starter doesn't turn the engine over?
: and the starter cranks the engine over but it doesn't start and run?
: and the car starts but turns off right away?
If the engine turns over but just doesn't seem to run check for spark, fuel pressure and injector pulse.

Is the security light flashing on the dash?
