Having issue with 2008 gxl d4d with 183000 going into limp mode constantly. Toyota says code comes up as ‘large fuel leak detected’ yet they cannot find what the source of the problem is.
From what I have read this code generally means loss of fuel pressure somewhere in engine. The only answer Toyota has for me is to start replacing parts one by one until the problem goes away starting with the injectors, even though all diagnostic testing of the fuel system shows no errors in any part of the engine.
The vehicle has always been service by Toyota and I can’t quite understand why they can’t work out the problem and if not why I am to pay for a step by step exploration to eliminate possible causes.
If anybody can help me with some ideas would be much appreciated
