Hey im new to the forum but scan it all the time. I need some help! My 04 wrangler x 4.0 runs fine when it starts,but starting is the problem at times. It will crank fast and strong but the gauges ie. Voltage and fuel are dead. Had it in the chrysler shop last week for two days they were getting "no bus" when hooked to the machine when it wouldn't start for them. But were left scratching their heads. This is an intermediate problem that is getting on my nerves. Im guessing its either a crankshaft sensor bad? Or computer on the way out , please help.
