I have a 95 chevy caprice classic.when i am driving it will cut off with no warning . i have replace the fuel pump an the fuel filter, but it is doing the same thing .what can be causing this ?
Try checking fuel pressure again with a guage on the fuel rail. If you still notice the pressure is low and you know the fuel pump is good, the fuel pressure regulator may be bad. Sometimes you can tell by unplugging the vacuum hose from it and if you see gas that means the diaphram is leaking. If everything checks out with the fuel system a bad EGR valve or EGR valve solenoid can cause cars to sort of stall under half throttle. Good luck and keep me posted. If you found this helpful please rate this solution.
