will your Catalytic Converter cause your gas guage to read different and also your battery meter and my truck cables on my battery are old and loose will that cause my truck not to run i have been told thats its prob my alternator but when i went to advance to get it tested they said that it was fine and i just replaced my battery[/quote:13b2fd16ed]

Your cat has nothing to do with the fuel or bat meter.

Replace your Battery Cables. A bad connection will cause a no start and gauge problems
