What is a fuel pressure test?
When it’s connected and the fuel system is pressurized, the tester displays the pressure in psi on a large gauge visible from inside the vehicle. This allows you to verify fuel pressure while sitting in the driver’s seat, making testing fuel pressure a one-person operation.
How do you know if your fuel pressure is bad?
Symptoms Of A Bad Fuel Regulator
- Engine misfires/poor acceleration.
- Black smoke coming from the exhaust.
- Spark plugs appear black.
- Reduced fuel mileage.
- Gasoline in the vacuum hose.
- Engine backfires.
- Engine won’t crank.
- Excessive fuel pump noise.
Will fuel pressure regulator cause car not start?
A bad fuel pressure regulator can create a difficult to start or ‘no start’ engine. If the ECU can’t measure the excess fuel coming through the fuel pressure regulator vacuum line, it will usually cause the engine to run rich (too much fuel). When the engine is hot, this can make it harder to start the engine.

How do you check fuel pressure while driving?
Check your fuel pressure when you first start your engine then check it again after the engine compartment has warmed-up. If it reads lower when hot as compared to cold, with the engine running pour some cold water over the gauge and check the pressure.
Do you need a fuel pressure gauge for a Honda Accord?
Using a fuel pressure gauge guarantees an accurate result. Now, in case you don’t own a fuel pressure gauge that has the adapter needed for your Honda Accord (or Odyssey or Prelude), you can check out some of my recommendations on which fuel pressure gauge set to buy and where to buy it: Which And Where To Buy A Fuel Pressure Gauge.
How do you test the fuel pressure in a Honda?
Screw in the appropriate adapter from your selection of brass fittings in your fuel pressure gauge set. Connect the fuel pressure gauge to this fitting. Have your helper crank the car while you observe the fuel pressure gauge. 1.) The fuel pressure gauge will register 30 PSI, or 2.) The fuel pressure gauge will register 0 PSI.

How can you tell if a Honda fuel pump is working?
CASE 2: The fuel pressure gauge registered 35 PSI while the engine was cranking. This test result lets you know that the fuel pump is working and is delivering enough fuel to the fuel injectors. This result has also eliminated the fuel pump as the cause of your Honda’s no-start condition.
