I replaced the starter in my 2006 grand jeep cherrokee a year ago(pain in the ***).I had a similar problem a few months ago where it was just clicking. I finally was able to start it, took it to the dealer and it was ok. Now it did it again i pushed it out of my driveway tried several times and finally started. It is fine now. Could it be the starter yet. Maybe a bad spot on it.It is only a year old. Is there any kind of otther relay that would affect it?. These trucks **** since chyrsler took over.

SOURCE: won't start. clicking under

sounds like a poss loose ground check all bat connections for corrosion/tightness.

THE THINGS YOU MENTIONED WON'T AFFECT CRANK SPEED. YOU'RE BATTERY IS PROBABLY ON THE WAY OUT THE DOOR. LOOK FOR CORROSION AND LEAKING BATTERYLIKE AROUND TERMINALS AND POSTS. BATTERY IS PROBABLY LOW ON CCA'S. NOW IF TALKING ABOUT WON'T START AND TAKES LONG CRANK TIMES IT CAN BE FUEL PUMP LOSING PRESSURE IN FUEL RAIL OR LACK OF FUEL PRESSURE CONSIDERING WHAT YOU MENTIONED. EVAP SOLENOID WILL USUALY SET A CHECK ENGINE LIGHT AND WONT AFFECT STARTING USUALLY UNLESS YOU HAVE A HUGE VACUUM LEAK

If it just clicks only once from the starter replace the starter comen problem on jeeps.

SOURCE: Rusty coolant and dead battery

You have several things going on here. 1. Rust in coolant (likely its a 4.0 or four cyl) A while back, the epa rules became so stringent about mpg that most better iron block engines had to be made thinner and from an alloy that has less zinc in it. Zinc prevents internal rust and acts like a binding agent preventing cracks from normal expansion and contraction. Flush radiator and block as well as you can and pray that larger chunk style particles don't plug up radiator. 2.Your charging system is able to keep a battery charged during normal driving, done at least once weekly. Sitting unused for long periods, even the simple memory in the radio can eventually kill it. I'd invest in a "battery tender"...Then, the computer will not loose its memory and the battery will stay in good condition. If you jumped a dead battery and got it started, the alternator may have been overtaxed and failed, as it's not designed to re-charge a battery, only to maintain it's state of charge . You need to get the system checked and squared away. 3. You need to determine where coolant is going. If there is nothing leaking externally then it's being lost inside the engine. Small leaks can evaporate on hot engine parts and not reach the ground...check hot, cold, with cap on, with cap off (don't open hot though) Rusty coolant points to possibility of insufficient antifreeze...if stored during colder months, this can cause cracks in block and cylinder head. Check engine oil for signs of coolant intrusion (coffee milkshake like residue under fill cap, white smoke from tailpipe are two symptoms) As far as being related, it all goes to kind of storage and maintenence it's getting. You can run these things 'till the body falls off if you take care of them.

First, make sure you can turn the engine by hand. If you can't then the starter can't turn it either. Have someone else turn the key and look for the source of the click...may be a relay. Go over the starting circuit with a volt meter. Check for power at the starter main terminal and then with the key turned to "start" check for power at the trigger terminal on the starter. Check battery voltage and check relay operation.
You have a neutral safety switch on the transmission if its an automatic and a clutch switch if it's a stick. Check them as well. Make sure battery grounding on fender and block are also clean and secure.
