2007 jeep liberty. Running fine one minite then next gas gauge/ fuel light/ 0-0 miles left car dies. So first disconnect battery, got new gas cap then dropped tank changed fuel pump, gas in tank. The information in top with temp/mpg/miles to empty. The gauge now seems to be working, gas light now off, check engine light off, but still 0-0 miles to empty. Haven't given the road test thats tomorrow. Any suggestions on my problem.
