1993 Grand Cherokee when the key turn on all ligh on but not move starter ,we have -30 outside no blockheater very hard start a couple time and drove a few times that day and at last doesn't work starter. is this a starter dead or crank sensor problem,please send your good answer. thank you. yuzo

Check the coil see if ur getting power to it

Sounds like a clogged fuel filter to me, maybe look into the TPS: throttle positioning sensor. Good luck

Sounds like the fuel pump is going out. Replace the filter first, as it's only $10. If that doesn't fix it, then it's probably the pump, which is $250.

Try swapping your wiper and starter relays. If it starts that way, your starter relay is bad.

can check these codes (if any) by jumping the A and B terminals at the diagnostic port under dash with key in on position engine light will flash and have to count flashes also sounds like it may have an air bound fuel system

first use your remote, lock-unlock-lock-unlock 5 times. use the key to unlock the door. lock with remote. If this fails, disconnect battery for 5 min. reconnect, should reset control module..

suggest a bad starter or a bad connection to starter, sometimes you can tap on the starter with a hammer and get it to start one last time.make sure cars in park with emergancy brake on!! have some hold key over in start position and you tap on starter with hammer to see if it even clicks, sometimes they will either click or even start, depaending on how bad the colenoind is on the starter. be very careful when tapping as not to cross out and hit the positive cable on the starter. hope this helps!!

If the connections to the battery are clean ,and tight,and the battery is good,and you know this for sure,then the starter is the problem,they are a low gear reduction starter,and are bad to do just what yours is doing,the starter is the most likely problem,if this was at all helpful,please rate thank you.

sounds like the key is either worn down to where the ridges in the key wont push the tumblers inside the key lock cylinder into their proper place to move the cylinder into the starting position. Or your steering colum is locked and the wheel is moving freely as if it were not. So your solution would be to either have an expert look at it (estimated cost: 200$ low/400$high) or you can attempt to fix it yourself.
should you choose the "I'll fix it myself" method....try getting a new key made at a hardware store since keys wearout over time (ie:10years of turning that old key), this may solve the problem right away if the ridges are just worn on the key. Or the hard way, you need to get a phillips screwdriver and some jewelers tools and an 8mm or 10mm wrench/rachet+socket to disconnect the battery, then underneath the steering colum just under the ignition is a hole in the colum shroud/cover, from there you can disconnect the ignition key lock cylinder (the thing you put your key into). once you've removed the cylinder from the steering colum you should test your key again to see if you can turn the cylinder outside of the colum if you cannot then buy a new ignition key lock cylinder for about 15$-30$...problems solved.

First, check starter terminals for power: large terminal should have 12v at all times (except ford type with remote solenoid) Small terminal should have 12v when key is turned to "start" If voltage readings are correct and battery terminals are clean, replace the starter. (clean means on the inside of the clamps, not that they look clean on the outside)If you have remote solenoid, testing is done at solenoid, following same procedure.
