fuel pressure regulator

[ds95]

after almost 18 yrs my 93 is it a good ideal to change the fuel pressure regulator? my car doesn't always start perfect in the morning, i feel like the gas its getting to where it needs to fast enough but it always starts. i've done the main reply and pretty much every thing else, what do u guys think.

you could replace the fuel pump that could have an affect

Aside from the fact that I can barely understand you...

it would be best to diagnose exactly WHY the car is hard to start, rather than just making assumptions and replacing parts. It could be an ignition issue, a compression issue, a fuel issue... honestly, it could be damn near anything. Replace your FPR if you want... but don't expect it to magically fix an undiagnosed problem.

fuel regulator

I had a problem with a slow start on the first try recently and having tried all the usual suggestions; main fuel relay, plugs, wires, distributor cap, rotor, check igniter, fuel pressure, I still could not find problem. Then on the internet I found a different remedy to check, ala Fuel Regulator! It said Honda Fuel Regulators very seldom go bad but to check pull off the vacuum line and check for fuel in the line. If their is fuel in the vacuum line the seal is bad. Also check the diaphragm is keeping the proper vacuum needed to keep fuel pressure in the line. Bingo! their was my problem I did not have the proper Vacuum coming to the fuel regulator, I traced it back to the intake manifold and found my disconnected cruise control vacuum line leaking and stealing vacuum from the regulator line. I plugged up intake connection with dummy connection and Honda slow start problem was fixed. Sometimes our problems are not always the usual problems, but this forum and the internet has saved me a lot of money on needless parts and shop costs, Thanks.

There we go. Now THAT is what you do when you suspect something might be a problem... test to see if it's faulty before randomly replacing parts! Very good info, rps... thanks.

before you replace anything, a fuel pressure gauge should be mounted and the fuel system should be diagnosed.

FPR = Fuel Pressure Regulator.
