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.

Re: 2006 grand cherokee laredo 4.7 wont start!

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!!

Re: 2006 grand cherokee laredo 4.7 wont start!

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.

Re: 2006 grand cherokee laredo 4.7 wont start!

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.
