Question about 2007 Jeep Liberty
Lisa, turnover means ZERO.
as the starter motor turns and so will the engine cranks shaft.
what matters 1st is the engine crank shaft.
if it spins, we say engine cranks perfectly and fast. robustly)
if that happens we next check fuses, and then for spark.
my guess is engine cranks ok, (you said have power, kinda implies that)
so check fuses yet, (we test them)
if fuse are good,
you next key on, the CEL lamp glows, telling you the EFI system
is read (fuel and spark computers)
if car is optted with IMMobilizer. (it is i think) the lamp for the IMMO
must to out for the car to start. if not , the IMMO will never let it start
if the IMMO lamp SKIM. its called, in your operators guide (lost)?
if that lamp out, then the key is good. (encoded key it is)
and the enigne will start or run only for 3 seconds.
ill stop here. and see if you have no starts at all, or just 2-3 seconds.
the PCM (EFI brain) will drop out the ASD relay in 3 seconds, for 8 reasons, all are told to you if you SCAN the pcm.
ill bet you dont have a scan tool so ill stop here
EFI means electronic fuel injection.

If your battery is charged up and you know its not the starter check all the battery cable connections. Check and see if the ends where they fasten on the battery is not corroded and must be tight. dirty and loose cables will not let the power from your battery to the starter. Do the same for the cables on the starter and also the ground. My cables on my Le saber looked ok but I could not even boost from another car. We replaced the both cables and Bingo away we go.
If that's not the problem check the switch as it might be burnt out as well but Its cheaper to check the cables first.

have same problem, ratan9 solution is pretty junk and I dont know why waste time posting it. After talking to local shop, to "test" the neutral safety switch, try to start in neutral, try to move shifter "farther" into park and turn key, listen to any clicks possible. If moving to neutral starts it you've got a bad switch. All the searching i've done it's either the safety switch, the ignition switch or a short in the harness somewhere

Ignition relay or fuse could be the problem. When you turn the key to start do you hear a fuel pump kicking on and or do you have spark when you hot wire the starter (I know it's hard to check while trying to start it)? You can email me back and I might be able to pinpoint it more.
