This was not a particularly difficult problem but I thought it was interesting. Engine would die out on acceleration and felt like it was running out of fuel. Customer said it happened all of a sudden. Checked fuel pressure at service port located at rear of throttle body. Fuel pressure was at 5 – 6 psi. Much too low 9-13 psi is the correct range with 12-13 psi desired. I disconnected the fuel lines at rear of car and hooked up my injector cleaning machine with internal fuel pump so that I could check the fuel pressure regulator for proper operation. 13 psi, great, diagnosis of faulty fuel pump.
I drained and removed the fuel tank and subsequently the pump and sending unit and this is where it got a little bit interesting. The fuel pump was not completely connected to the sending unit by the rubber hose and there were no clamps present.
