Hello and thank you for trusting us with your question. I'm DJ.
A code 12 is very rare. What it means is that the ECU (engine computer) isn't seeing a signal from the distributor when the starter is running.
There several different things that can cause this code.
But first I need to know if the engine starts and runs.
Does the check engine light stay on all the time?
Please let me know and I'll show you how to diagnose and fix this problem.
