scan codes and post so we can adv
What do mean scan codes? How do I do that or find that. By the way thank you for helping me ? I just put in new camshaft position sensor. Would that anything to do with it still not starting? Do I have reboot something?
i rec you have codes scanned by a mech. codes let you know what system has a malfunction,without that i can"t help much.
