Mechanic Job in Cincinnati, Ohio

it stopped working yesterday while i was on the road it just stopped so i thought i ran out of gas .. it has been having misfire and stalling ...filled lots gas in it on the screen still wasn't accurate..right now it cranks like its about to start and goes off..i tried pressing the gas paddle while starting the battery died after second attempt so it came to my understanding i could have bad camshaft position sensor its a 2009 nissan maxima 3.5L i am really looking to get it fix soon as possible so i can go back to wrk before i get let go
