    93 civic low fuel pressure. Hard accel is no good
    Hey,
    I drive a 5speed 93 honda civic 1.5vtech.. theres probably more then one problem :eek:
    K first off my car starts kind of good when I start it off in the morning and also when I start it, at idle it shows that its at around 1500 rpm , then after I drive it a few min.. a few stop lights later the rpm gets lower and lower at idle and sometimes it stalls randomly at full stops….on a hot day it takes a few tries to start but it does eventually start...

    then, if I step on the gas hard it doesn't accelerate, but if I slowly step on it works fine….the longer I drive it, it seems the slower I have to gas it, and when I change gears at high rpm it works fine when I change gears and rpm is less then 2000 for the next gear it gives me that problem and I have to slowly gas it…I got it checked at a shop…they say its at 25psi for fuel pressure …and they said it's the fuel pump…. I changed the fuel pump still no good….then I changed the regulator and fuel filter still no good….
    does anyone have ne idea what is causing the low fuel pressure?

    Remove the Ignition Control Module and coil and have them tested free of charge at AutoZone. This is a good time to replace the rotor and distributor cap. Also, replace the spark plugs with the exact NGK plugs that came in the car.
