Starts, dies after 2 seconds, sentry key?
2001 Grand Cherokee 4.0. Car has been sitting for 3 months (but had no issues before) and battery went dead this weekend. Replaced with a new battery, car started and ran first attempt in the driveway. Parked it, turned it off, ran an errand, went to start again and it fired up and then died 2 seconds later. Yellow "sentry key" light illuminated on dash, along with red "check gauges" light and low fuel light. Tried repeatedly to start and it continually shuts out. I can hear the fuel pump when I turn the key, I know it's working.
Car has a full tank of gas. If I put the key in the "on" position, the fuel gauge and voltmeter do not move like they are supposed to.
I unplugged the battery for 30 mins or so, reconnected, tried again and of course it fired. Drove it home, turned it off, tried to restart, and once again it will not start and stay running.
Where should I start? I only have one key for this car. All fuses look good.
