P0093
Fuel System Leak Detected - Large Leak
DTC P0093, sometimes indicated as P009300 is an OBD diagnostic trouble code indicating a generic fault with the vehicle powertrain (i.e. engine and gearbox). This code identifies an error with the air/fuel mixture causing fuel system leak detected - large leak.
The P0093 code means that there is a large fuel system leak. This can be caused by a number of things, such as a bad fuel pump, a cracked fuel line, or a leaky fuel injector.
The best way to fix this problem is to find and fix the source of the leak. If you can't find the leak, you may need to replace the fuel pump, the fuel line, or the fuel injector.

2006 JEEP LIBERTY with 99000.0 miles
Several things 2 list: vehicle = 2.8l diesel Jeep Liberty, 2006. The codes are P0093 & U0121. 1st) it says a large leak in the fuel system. Something in the emission system. Has happened several x's. I've had it towed 4 this. Engine runs rough & quits @ x's. No power. Changed fuel filter & did air leak test in the fuel return system / tech at dodge Jeep dealer. No air in return line found. Problem still exist on an intermitant & sporadic x frame since june 2010. Last x occurred = 8-20-10ish. 2) low boost from hole in the waste gate actuator vacum tube from improper routing at factory. Found by tech at Jeep dealer. 2 visits many hours & $$$. Egr valve replaced @ same time. Big $'s. 3rd) belt squeak from bearing going out in a/c compressor /dealer tech??? 3rd visit. Need a/c compressor he says. Previously changed tensioner pulley for this problem but did not fix problem. They now say its the a/c compressor??? 4th) right rear electric window motor failed 10-2-10. Replaced motor/regulator assembly 10-7-10= $172.99. I should be reimbursed for all parts & labor for these damages. I paid a lot of $ for a supposedly good vehicle but it keeps failing. 5th) part time 4x4 light on dash says its in part time 4x4 when in two wheel drive. Haven't repaired cause of $. Please note that because of low power i was almost in several accidents because of the low turbo boost at acceleration. There could be injuries or fatalities in the future if this happens to someone else that's not mechanically inclined and not aware of reduced engine performance of a turbo failing slowly like mine because of a small hole in the waste gate actuator tubing from vibration on the housing bracket by the tube. Was replaced and rerouted by dealer tech.
