    I had the same problem all summer. Along with the car randomly "reving" itself without my foot on the gas (sometimes up to the 8 on the RPM dial). After this "reving" the engine malfunction light would come on. Mechanic replaced the TPS (Trottle Positioning Sensor) and I haven't had either problem since.

    I replaced the starter and the battery and still wont start. What next?
    It will click one time when I turn the key over but that’s all. So I think the starters getting power.

    My 05 jeep grand cherokee has the exact same proble. sometimes won't start, power turns on wont take a jump and then makes one click noise but won't start. The car dealer said they cant find out whats wrong with it because now it is running. I am so mad. I don't know what to do. (Key Auto Center in Somersthworth NH.)

    my jeep 2005 starts when it feels like it. all the lights turn on but it will not start! what can it be?

  • Anonymous Mar 21, 2009

    Brought a 2005 JGC home from the dealer for an over night test; parked it in the driveway hasn't started since. I'm affraid this is why they were selling a fairly low mileage, very clean vehicle at a low price.

    Same problem with just one click, but battery appears charged. Took it to a shop, and they are going to replace the starter. I'll update with the answer.

    Where is the starter located i've looked and looked and can't seem to find it?

  • PowerOne Jun 25, 2013

    i had this problem and per a suggestion, I wiggled the yellow wire connected to the starter and this solved the issue. I had to lay on my back and spot it with a flashlight and could just barely reach the starter wire connectors. When I got home, i pulled the front driver side tire and removed the plastic cover and put some NoOx on the connector. Hopefully, this is a long term solution.

    Some time ago, my '05 Jeep Grand Cherokee suffered from the same problem most of you are describing on this forum. After reading through over 100 posts, I found what I thought was the most "logical" cause... the 'push on' female connector on the starter motor solenoid. After visual inspection of the connector and finding that it is the spring clamp type, I knew that I had indeed found the culprit. This type of connector operates in a similar fashion to a clothes pin. When you slide it over the male side of the connection, it spreads apart the two metal pieces inside the female connector. Over time, the connection becomes both loose and corroded due to exposure to the elements.

    Once this begins to happen, as long as the battery has a high enough charge to overcome this corrosion, the Jeep will show no signs of a problem. However, if the battery level is low or the weather too cold or too hot, too wet, too dry, whatever, there is NOT enough power supplied to this connection to overcome the corrosion; and, the vehicle will NOT START.

    Jump start, charge or replace the battery: Now it MAY have enough power again (at least until the corrosion builds up even more) to start the engine. That is, until the next time it decides to act up.

    Replace the alternator, same thing as above. With a new alternator providing full charging power to the battery, once again there is enough power to overcome the corrosion on the terminal and allow the vehicle to start.

    Replace the starter, same again. In order to replace the starter, the connector in question has to be removed from the solenoid. When it is put back on the new starter, one side of the connection (male, on the solenoid) is new; so, problem goes away. After several weeks/months/years, the corrosion returns and so does the problem.

    Banging on the starter solenoid or wiggling the wires may 'scrape' off the corrosion enough for it to make a good contact and start... for the time being.

    In other words, while seeming to 'fix' this problem, all of the steps above will only prove to be temporary. While some might just clean the offending connector(s), the problem with recur because nothing has changed. You are still using a badly designed connector. The real solution is to REPLACE the female side of this terminal with a better connector, preferably one that doesn't use spring pressure to 'clamp onto' the male side. Of course you should still clean the male side before pushing the new terminal on.

    Putting some dielectric grease on the connectors before connecting them will extend the service life of this connection even longer.

    Bottom line: after having this problem off and on for about two months, after replacing the connector... a 25 cent part... it has now been more than six months without a single instance of failure to start.

    Fixing this connection is definitely where you should... START. (Pun intended ;-)

    this is absolutely correct. I've been battling this issue for 2 years now. it is the crimped connector at the starter.

Check the ground cable, it is kind of with the starter cables, if it is loose it will not start all the time, this happened to me with my 2005 Grand Cherokee. This solved my problem maybe it will solve yours?

05 grand cherokee wont start .full power lights dont dim when cranking then it starts like nothings wrong. i tried jump starting it then i climbed under it and hit the starter and it started

If the starter motor spins at high speed, but doesn't turn the engine until you whack it, the starter gear is not engaging the flywheel. Probably the engagement fork or the starter gear is worn out or sticky, or the solenoid isn't pushing it far enough.

I drove the Jeep home with no problems. This morning, it won't start -- no power at all, no radio, light, power lock, power window ... nothing works but I keep on hearing a fast "tick, tick, tick" sound...

Your battery is low or has weak cell. I recommend jump starting vehicle. If it jump starts then replace the battery. If
battery warning light is illuminated on dash may have charging
system concern.
