How is the gas pressure regulated in a Honda Accord?
That pump gives off a constant pressure and that pressure is then regulated to the fuel delivery rail by allowing some of the pressure to bleed off back to the gas tank on a return line via the fuel pressure regulator.
Why do I lose acceleration on my Honda Accord?
I have a 92 Honda accord EX the fuel pump was replaced 02 upstream replaced and when I push on the gas I lose acceleration as well mechanic checked the pressure said it was fine but than there is so much pressure in my fuel that every time I pop the gas cap so much air comes out n than it runs fine for a little bit idk what else to check for.
Where is the fuel rail on a Honda Accord?
The fuel rail on your car is a shiny aluminum stick that runs along the back side of the engine between the engine and firewall. The fuel pressure regulator is located on the drivers side of that rail. You also may want to have a dealer run fault codes on the car. That car is equipped with an OBD interface under the steering column.
What are the problems with a Honda water pump?
If the vacuum is low and the engine speed is correct, there is an internal problem with the pump (worn components, etc.). If the engine speed is too low, there is a problem with the engine (engine worn out, governor problem, etc.). Low discharge capacity or pressure. Excessive head loss due to restricted discharge hose or very long discharge hose.
Why does my Honda engine hesitate when I accelerate?
While you are most likely to notice engine hesitation when you’re accelerating, engine surging can occur intermittently. Figure 3. Reduced engine power can be attributed to a clogged fuel filter or faulty spark plug wires.
What causes the fuel pump to stop working?
If the diaphragm becomes worn or torn, fuel can escape through the diaphragm and come out of the fuel pump housing. Eventually, these will fail completely, causing the engine to stop running. As the fuel pump produces less pressure, the engine fails to operate.
How can I find out if my fuel pump is bad?
Screw your compression gauge hose to the hole of the spark plug. With your hand, twist the throttle position wide open. With your other hand, pull the rope start, or turn the starter over to turn the engine over four or five times. Read the compression gauge in PSI ( pounds per square inch ).
Can a bad outboard fuel pump cause a hard start?
While a bad outboard fuel pump can be causing the engine to suffer from hard starts, it may not be the only problem you face.

This is due to the fact that when you shut off the engine with a low fuel level; the fuel can drain from the priming chamber designed into the fuel delivery system. So when you restart your car, the pump runs hot and un-primed until it can refill the fuel chamber. Over time this will burn out the pump motor.
What should fuel pressure be when no Buzz?
Fuel pressure is typically in the 35 to 45 psi range. If your Anti-Theft light is flashing; the anti-theft system is disabling the fuel pump to prevent the engine from starting.

What to do if your fuel pump won’t start?
Use a circuit tester to check all the electrical connections to the fuel pump. Turn the key to ON. If you see a current, then it is not the pump. If there is no current, check the fuse.
