It all started when I was trying to leave the store, everything was fine beforehand but when I went to start it up, nothing. I tried jumping it and nothing, I checked if the battery is good and it is. We then thought it was the starter and had it checked and had it replaced because it was about to die. Still nothing. We then found out that the crank position sensor was giving a lot of resistance so we changed that out with a new one. Still nothing. We've checked all the fuses and wires and everything is in check. The only thing left that we can think of is the ignition switch but I don't want to get into that unless that IS the fix. Any advice would help! Thanks!
