(SOLVED) Weird fuel pressure symptoms
Alrighty here goes nothing… My idle fuel pressure is at 9,000 psi I have tried commanding it higher or lower with my tech 2 to no avail. I disconnect the FPR no change. If I disconnect the Fuel Rail Pressure Sensor I am then able to command a change of pressure with my tech 2. 2005 GMC Topkick...- PressPause
