Can a fuel pump intermittently work?
Can a fuel pump relay work intermittently? Yes, some things can make a fuel pump relay to work intermittently. When fuel is not passed into the engine, apparently, your car won’t start or even move.
Can a bad fuel rail sensor cause a stall?
Improper supply of fuel to the engine will cause an unexpected stall. No matter what you try, the engine will often not start again. If this happens frequently, the fuel rail pressure sensor might not be working properly enough to send the correct information to the vehicle’s onboard computer.
Why does my car not start at the rail?
I have no fuel preserver at the rail but got great fuel pressure at the fuel filter . This all started while I was driving and when I went to take off from the stop light the car just shut off and won’t start up it cranks but won’t fire up .
Why is there no pressure on the fuel rail?
If the pressure at the exit side of the fuel filter is normal and yet the pressure on the fuel rail is essentially zero, it’s possible the fuel pressure regulator has failed wide open, essentially preventing sufficient pressure from building.
What happens when the fuel pressure sensor doesn’t work?
When your fuel pressure sensor doesn’t work like it should, you’ll notice a considerable reduction in fuel economy and mileage. Either your engine control unit will send too much fuel or not enough fuel through the fuel rail and into the combustion chamber.
What happens when your fuel rail pressure sensor goes bad?
When your fuel rail pressure sensor goes bad, the “Check Engine” warning light may illuminate on your dashboard. This light activates whenever the engine control unit detects an issue within the vehicle that affects the engine in some way.

Why does the fuel pump not release the fuel?
The fuel pump is able to create pressure using electricity but if it is not getting the adequate voltage of electricity, it will not be able to function properly. Consequently, the fuel will not be released at the perfect pressure and your car will lose efficiency. Although, voltage fluctuation in a car is rare, it is not uncommon.
What happens if the fuel pressure regulator fails?
The fuel pressure regulator controls the fuel pressure in the fuel rail. If there is something wrong with the fuel pressure regulator, it can create too low or too high fuel pressure in the rail. It is not very common that this part fails, but it can happen.
