i tried to search but nothing came up. i just had a question how do you fix a car that doesnt hold pressure. is it the fuel pump? i have already changed the fuel filter and the inj. what else needs to be done

 

How do you know your pressure is too low? What kind of pressure are you getting? With a fuel pressure guage connected, and the vacuum hose disconnected from the regulator, you should have 47-54 psi according to genuine acura manual. Reconnected you should haave 38-46 psi assuming you have a b18c1,bi8c5....b18b1 have slightly lower pressures. Most likely sounds like the regulator giving you the problem if pressure did not go down after putting back on the vacuum hose.
