If the tail smoke is blueish (not dark and sooty) and the engine runs right then it's a leak. Put the car on a clean flat surface, start the engine and look for the leak - start with the fuel tank.

If your Jeep is equipped with a 4.7L V8, go to check each ignition coil and spark plug careful. It's a problem at all. Coils are ofter misfires to the engine head housing. Check the pressure of your fuel system too. next problem to this engine are the injectors. There is a little filter inside of each. it can't be replaced, but cleaned. If you remove the injectors you need to see the same spry picture on each of them. If one injector don't spray correct, replace him.

Jeep Grand Cherokee Limited P0700 diagnostic problem


P0700 means there is a transmission fault code in the transmission controller. Since the transmission controller doesn't have a light attached, it tells the engine controller to turn the light on using this code. You'll have to access the transmission controller to further diagnose the problem.

Sounds like the ECM has failed. Most likely caused by water damage. It would probably do well to pick one up at a junkyard but if you've got this must catastrophic of a shutdown of the engine and all of it's components then the root source will be the ECM. Hope this helps. Good Luck!

Delay in Ignition and High fuel consumption


have you checked the fuel pressure regulator (usually found on the front end of the fuel rail.) The pressure should be around 31lbs with the vacuum line on, 41lbs with vacuum line off. An exceptionally high reading may indicate a blocked or pinched return line. Delay in starting may be due to too much fuel going into engine on start up. Any black smoke out back or excessive carbon residue in end of tailpipe? This isn't really a solution but some suggestions on where I'd be looking.
good luck!
