I have a 2008. 4.0L FWD. I had starting problems for a while now. I have put two rebuilt starters in it. A brand new battery, a new alternator, replaced battery terminals. Put in a crank shaft sensor in it, replaced the acuator pin and wiring harness.

It sometimes starts on the first turn, and then sometime it takes 10-15 turns of the key. I've put it in nuetrul and tried, no difference.

If there is anything else I can do or if someone knows the problem. I would be greatly appreciated. I've put about it $600 in it so far.

 

How are your grounds?

 

I think they are good. Which ones should I check. From the starter to the block or frame?

 

I would check the one coming off of the fuse box - as the engine rocks it can put pressure on it.

First try an old trick - while you stick your key in the ignition and turn, try squeezing the key where the batterycase comes to an end on the side the key pokes out of. Squeeze it pretty hard.

 

A little late to the party here...
Does it crank but not start the engine or not crank the starter? The anti theft SKREEM module may not be recognizing your chipped key if not letting the starter work. Do you have a second key to try?
