The engine was hard to start (it did not reach the no start situation). After a repair shop kept the truck for 4 days they diagnosed a bad fuel pump. The repair cost for the new fuel pump plus installation was about $1,200.00, which I thought was outrageous. Will not use that repair shop again.
Truck won't start on first try esp if the ac is on. Turn the ac off wait a few seconds then it will start right up.
Won't crank after it has been sitting for a while. It will turn over but not fire up. On the second try, it will crank. Was told it was a bad fuel pump. Not fixed yet but got estimate of $696
