The power for the shutoff relay actually comes from a secondary winding on the ignition coil itself. Why the enging would shut the fuel pump off is that as the engine ran for a while the coil gets warm and then breaks down or opens up the circuit for the fuel shutoff relay. Fixed by replacing $85.00 coil.
I have an 87 Accord with fuel injection that always had a fast idle, and a surging problem when warming up. Both problems went away when I replaced the fast idle valve, which is bolted to the rear of the intake manifold just downstream of the throttle body.
hello if this is carburated look inside the carburator front inside at the wall look for crack or cracks on the inner walls check all hoses for cracks dried rubber you can usually find exterior vacuum leaks with a can of carb cleaner lightly spraying around base of carb but extreme caution has to be taken when doing if your not that experienced i wouldnt advise this if your car is equiped with tps sensor check for possible out of range sensor goodluck
If you can keep the engine running with your foot on the gas at a stop it is likely to be the Idle control valve. Older Hondas' have 2 valves. fast idle control (which is prone to cause fast, or surging idle due to vacuum leakage) and the Idle control that takes over from the cold idle control once warmed up. They are located at the throttle butterfly assembly.
