Hey guys what's up? Yea i'm a newbie to this forum but a motor head since i was 15. Always drove/fixed/rebuilt Mopar muscle cars (13 engine's under my belt) Got a question for you guys. My jeep been sitting for 3 years. Had it since 2010 I'm not to savvy when it comes to electrical stuff. I gave her a complete tune up. Lubed all the pistons changed all the oils, engine, tranny, transfer case, front and rear axles and new gaskets on both and a new AutoCraft Gold Battery from Advance Auto Parts. Engine wouldn't crank. Didn't hear fuel pump kick on and fuel gauge didn't move even after putting 5 gals of gas in tank. checked the relays fuel pump relay, ASD relay and horn relay all the same. Switched with horn and they all work. Checked voltage at relay's and voltage was present. (26-volts, does that sound right?) used ignition to get codes and i got 12-42-42-42-55. I know what the first and last codes are but 3 code 42's?

I'm all ears brothers all help appreciated
Thanks a Bunch, Bruce
