my 2005 jeep grand cherokee 4.7 v8 starts sometimes then won't start all the lights come on for power just won't turn over?
And the times it doesn't start, you just hear a click? Sounds like your starter solenoid is dying.
Here's a picture of a 2005 Grand Cherokee 4.7l starter. If you have a multimeter, you put the red probe on this bolt (assuming it's the positive terminal) and the black probe on a ground, like this nut. You have someone turn the ignition key and if the meter reads 12 volts, then it's the starter/starter solenoid. If it doesn't read 12 volts then you have to go check the starter relay, but your symptoms sound like the starter solenoid.
maybe check your battry ..terminal and pole.. and cable ..and also check starter nuts.. if have poor connection,,rust or losse.,,just clean///.. if ok ...check the starter and solenoid ...best thing is to be ,,is cleaning all connector terminal and check the battry(make a test whit a batt. diag tool) is has a good amp and volt .. or replace the batt...or if the starter go bad,,,replace it... my advise .. good luck!!
