What should the fuel pressure be at 60 mph?
Vehicle cut out at about 50-60 mph. The cut out is abrupt and intermittent. There are no code from the PCM. Pressure when checked at fuel rail was around 30-32 psi with vacuum, up to 45 psi with vacuum unhooked. Vehicle seems to surge a little bit. helpful? Fuel should be 30-45 psi with key on engine off.
What should fuel pressure be at fuel rail?
Pressure when checked at fuel rail was around 30-32 psi with vacuum, up to 45 psi with vacuum unhooked. Vehicle seems to surge a little bit. helpful? Fuel should be 30-45 psi with key on engine off. Try a new fuel filter if pressure okay tested like I said. Then clean throttle plate on both sides and IAC hole. helpful?
What is the fuel pressure in the tank?
With the fuel pump removed from the tank in a bucket of fuel it reads 80 psi. The engine check light is on and it says all three O2 sensors have low/slow response.
Is the fuel pressure in my car low?
The engine check light is on and it says all three O2 sensors have low/slow response. It has 102,649 miles and the fuel trim is 100%. I suspect the fuel pressure is low. have the same problem? You do not have a four cylinder which one six or eight? helpful? Sorry, I meant six cylinder OHV. helpful? Your pressure is within spec.

What happens if the fuel pressure regulator is not working?
If the fuel pressure regulator is not maintaining exact fuel pressure while the engine is running, it can cause the engine to run rich or lean, and in the event it goes too far in either direction, the engine will stall out due to an inability to properly burn the air/fuel mixture.
