Recently had my engine wiring harness replaced and now it won't start because of the security light flashing on the dashboard anyone know of this problem? Could it possibly be the starter relay? And is there anyway to bypass the security mechanism to get it to start?

Im assuming the engine wont turn over.

Check your clutch/neutral safety switch; make sure its all good.

Also if you feel it is your security system, maybe you can disconnect the battery for a couple minutes to help reset it and bypass it.

This is a known problem. You're stock alarm is malfunctioning. It's a silver box by your ecu (has a blue plug on it) remove it and see if that does the trick.
