Pulling into driveway noticed tach wasn't working. Parked and revved engine, no tach. Tried to put into reverse, shifter (auto) would not unlock.Turned Pathfinder off would not start thereafter. Did some research and it sounded like the inhibitor relay so I pulled it and jumped it and it started! Replaced the relay with a new relay and nothing. Take relay out and jump it it starts. Leaning towards ignition but it's a costly part to just replace and get no results. Any thoughts would be greatly appreciated! Thanks!
