2006 grand cherokee laredo 4.7 wont start!

[thre3kgt]

just bought this car about 3 weeks ago and within a week of having it i went to get in it and the car would not turn over at all but i still had full power so its not the battery...had it towed to the dealer they said they fixed it and it was the kill switch relay or something...car was fine for another week and this morning i encountered the same problem..Is the dealer screwin me or whats goin on here anyone ever have this problem before? Ive done some research before posting and didnt find much except some people saying something about a security feature or a fuel pump relay..please help!!! thank you!!!

a fuel pump would allow the vehicle to crank but not start. I would call the dealer and take it back.

If it won't crank over, it is in bat terminals or connections.

Is there an alarm on it? I've heard of aftermarket alarms causing this issue.

bit of an update...took the car back to the dealer for a second time..the first time they replaced some wires apparently near the kill switch relay..then the second time they replaced the actual relay... car was fine for again about a week then what do u know it happened again car just wouldnt start! its not the battery terminals their fine and no there is no aftermarket alarm just the regular one. Now they are saying they are going to replace the starter im not sure if this will help or not i just really feel like im getting jocked around can anyone please help!!

Starters can have bad spots in them and when it stops in that position, it will not do anything when you turn the key. When it happens, try turning the key forward very slowly to see if it is a bad contact in the ignition, might start at one point but not when you turn it further. Also try starting in neutral or try turning the key to start, put your foot FIRMLY on the brake and move the shifter out of park and down to drive SLOWLY going through the gears, could be a bad/out of adjustment park/neutral position switch. If neither of those work, just try turning your key forward a couple times while having someone tap the starter with a small hammer or something.

one way to check if it's a starter is to do a starter draw...I also found bad battery cables. try and check if your vehicle will start when you jump it. You need to try and connect the positive side of the jumper cable to the post in the PDC it's in the engine compartment.
