Re: 08 Liberty Starting problem
After dealing with this problem for over a year the dealer finally hit on something that was illogical to me but worked to repair the problem. The mechanic ran tests on the Jeep and found that the fuel pump was loosing pressure. It was bleeding down more than specifications allowed. When I was told this information I said there was no way this was causing the starter to continue cranking with my hand off of the ignition switch. Made no sense. If the fuel pump is failing it would result in longer cranking time to start the engine but not cause the starter to continue cranking on its own.
I finally approved the fuel pump replacement. Since then, the starting problem has not happened at all. Somehow the fuel pump must send a signal to the computer to make the starter continue to crank even though the key is in the run position.
If you are having this problem I would recommend that you have the fuel pump pressure tested. If its bleeding down outside of specification, replace the fuel pump.
