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

Check battery condition and connections (dirt, corrosion, tightness, acid level) to start with.

It could be the neutral starting switch..You can wiggle the gears and it will start

Low fuel pressure or problem with spark plugs or crank sensor is got dirty and needs cleaning or its time to replace crank sensor.


Check out the help links shown below for no start problem and cranks but no start problem.

Thanks.

if you have theft security problems if you jump start the vechicle it still wont crank.have battery load tested and checked battery could be weak.your current drain can be caused by many things, like radio,faulty power lock, dome light remain on,faulty pcm,faulty alternator,faulty heater blower motor relay.

9 times out of 10 it's the realy but check if stater is getting power to crank wire

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.

Bad solenoid i would guess. Not making a connection there. Any basic wiring and ignition switch problems should be alleviated by jumping the starter with a screwdriver. I would check the solenoid and starter brushes

check for ignition voltage at the purple wire in the starter when you open ignition to the crank position , with a test light,, if the light light on them you need to change the starter..

try over riding the starter relay on the fender ,it has one there right?. dont go to a mechanic yet. the engine aint seized. if it doesnt have this relay then i would get the alternator tested. if you want to test it yourself it can be costly for the right equip. autozone usually tests for free. i dont know were you live so if theres not an autozone. let me know if you cant get it tested.

does your light dim when you try to start it?Check ING fuse under hood.
