Hi I have a 1989 Honda Accord LX-i. I have replaced my fuel filter, cap, rotor, spark plugs, spark plug wires and cleaned out my idle control valve and cleaned my throttle body. when I disconnect the fuse for the fuel pump I hear it disengage and engage when plugged back in.My car will start fine in the morning but sometimes at high revs it doesn't want to choke and sometimes at stop lights it will want to die on downshift and sometimes is slow to start almost in a dieing fashion. Also, it doesn't want to start if its warm at all by any means. When it doesn't start it smells flooded. When I first changed my fuel filter it worked amazingly well then slowly over a couple days went back to the same mess ups. Same thing happened when I cleaned the throttle body. My main relay seems to be working seeing as how I hear three clicks. I'm wondering if it would be either the catalytic converter, electric choke, leaking fuel injectors or what. Also, my car will start warm if I disconnect the fuel pump fuse but it just won't stay started because there is no gas. I'm not taking it to the dealer....
It sounds like the engine may be flooding after shut off. It is possible that a leaking injector could cause this. Hooking up a fuel pressure gauge and watching what it does after you shut the car off may give you a better direction to go in.
You don't have to take it to a dealer, but it will be more cost effective in the long run to have a qualified technician diagnose the vehicle than it will be to continue throwing parts at it.
