Starting problem
I've got an 03 grand cherokee laredo. I replaced the battery about two weeks ago. I just tried to start the car and it wouldn't. Everything lights up but the engine won't even crank. Back when the battery was bad if I tried to crank the engine i'd get a clicking noise, but i dont get a noise this time around. any ideas?

Re: Starting problem
That clicking noise is the starter solenoid. If you get lights but absolutely no click when you try to turn over the engine either you are not getting any power at all to the solenoid or it went bad. Check the fuses and relay for the starter first, then make sure the cables to the starter are good. If that all checks out ok then most likely the solenoid/starter motor needs replacing. I believe they are all one unit. Hope this helps you.

Re: Starting problem
The starter relay is in the PDC and there are several other same relays in there, so you can swap them for trouble shooting. If this doesn't help, you could hit the solenoid with a hammer or so (not too hard ofcourse:rolleyes:) and see if that helps. If yes, your solenoid is bad.

Re: Starting problem
I had the same problem first was the starter, changed it and the problem was fixed and then the same symptom but was the battery.

Re: Starting problem
I checked all the wiring, fuses, and relays and everything looks good. the dealership told me that it could be either the starter, the ignition switch, or the neutral switch. whats next?

Re: Starting problem
actually it just came to my attention that the starter relay thats in the fuse box under the hood isnt the only starter relay, does anyone know the location of any other starter relays on an 03 WJ?

Re: Starting problem
There are some fuses under they dash on the drivers side, also on the side of the dash when you open the passenger door i believe. Your manual should say, if you dont have one check out Try wiggling your trasmission shifter, I had a problem like that on my old ZJ where the neutral switch was going out, wiggling the shifter would be enough for the switch to make contact and allow the vehicle to start.

Could be ignition switch, but the only time I have seen problems with that you would know it when you tried to turn the key, it would be loose instead of offering resistance.

Good luck!

Re: Starting problem
replaced starter and didnt solve my best guess is the neutral switch im guessing?

Re: Starting problem
There should be only one starter relay and one starter solenoid. The relay is in the PDC and it switches the current to the solenoid, which is part of the starter. The solenoid in its turn connects the starter motor to the engine and switches the high current to the starter motor. There is a 40 A fuse in the PDC (fuse 8) and a 10 A fuse on the junction block (fuse 31), under the steering wheel.
Did you feel on the starter relay if it clicks when you try to start? The click is very light, so you really have to feel it. When no click, most probably everything after the relay is ok and your problem is the neutral switch or ignition switch. You could remove the starter relay and check for 12 V between point 86 and ground when trying to start. When ok, your ignition switch is ok.

Re: Starting problem
I checked all of the fuses and relays and everything was ok. I replaced the entire solenoid/starter and that didn't solve my problem. I was told that if it was the ignition switch that needed to be replaced then there wouldn't be much resistance when i turn the key but there neutral switch is probably the problem right? Where exactly is the neutral switch located?

Re: Starting problem
ok so i took a look at what i believe is the neutral safety switch. it was above the oil pan and pretty easily accesible. what i found was what almost looks like something chewed through the wiring. now the wire still connected to the neutral switch is much to short to connect via connector butts or anything of the sort? im 150 miles from home. what can i do to get it working so i can get home?

im not sure if it is the neutral safety switch that i found though because it looks nothing like the pictures ive seen or pictures of replacement parts
