Was curious if anyone has ran into a similar issue. To start, I had to change the alternator and battery about 3 months ago. This issue started a week ago. Lights and everything come on and arent dim. It tries to turn over but won't start. When its switched to on it shows the check engine light (which stays on) and the red lightning bolt which stays on for about 3 seconds and then turns off.
