Took my car on a 3 hour trip about a week ago. Without any prior issues or difficulty starting the car when I got back I didn’t drive it for 2 days and when I go to start it, the car cranks but won’t start. I replaced the battery knowing that wasn’t the issue just bc it needed replacing and to rule it out altogether. It wouldn’t get started by jumping anyways. I checked the fuses, all good. Tried using starting fluid in many different areas around the air filter to rule out a fuel problem. Next I’m going to check spark plugs and relays but if those are fine too I don’t know where to go from there. Any ideas?
