Code reader not working

Helpful hint on code readers,I have found in a few instances that if the cigarette lighter fuse is blown you will get nothing from the computer other than a link error message. Always good to ck, also if the ck engine light is not on (other than a blown bulb maybe), you will not get any help from the computer. Hope it helps, J.T.

I have a 2000 Jeep Grand Cherokee 4.7 that will not crank/start. Initially I was able to get it to crank and start a couple of times by holding the key to the start position for 30 seconds or more but had to do this numerous times to get it to crank and start. The dash "-brake light" stays on as does the "Check Gauges" light and the speedo does not work.I believe the compass and temp gauge also is locked at the last reading and does not change. I removed the ECM to check the connections as well as the fuses and put the ECM back. In doing so I did get it to crank by holding the key to start for 30 seconds 5-6 times but now it will not start. Any suggestions folks? Thank you for any help you cam afford me. The rig is stuck 38 miles up a mountain road without tow truck access.

When you do that Crank Sensor the bolts on them are stop bolts. You cannot tighten them like regular ones, they will break. Just tighten till they stop, then just a bit more with a small ratchet so you do not have much leverage. Go easy and you should be fine.

In Texas we are required to have a state inspection, before being able to register a automobile. Now, my problem is my JEEP Grand Cherokee, 4.7 liter 2 wheel drive is showing the engine light on. So I have taken to a few different JEEP Shops, and still no dice...

Problem: I have replaced Throttle position sensor, I have replaced solenoid, leak detection pump, and smoked the EVAP system. So there are no leaks, and well the Firestone place said they tested it, and that it is the ECM... Now the deal wants $600.00, and Im thinking junk yard, and replacing it with a used one, SO do I need to reprogram it at that point? is the dealer the only ones that can do that? or is there perhaps something I'm missing here....? Help Please

Keep in mind the jeep runs strong, I drive it daily!

If you have a 4.7 L Grand Cherokee, you should posting questions in the Grand Cherokee section of the Forum.

.

A recent Gallup public opinion poll shows the NRA, at 58% approval, has a higher approval rating than either Hillary Clinton or Barack Obama.
