Hey i have a 92 civic hb i have a problem with the car starting because the fuel pump takes for ever to start up and i think its getting worst i dont kno if its the relay or what please help

Could be just air in the line, will take a bunch of cranking to get it out. Fastest way is to pour a bit of gas into the throttle body and start the car . Do that a few times while pumping the accelerator pedal and it should get rid of it and start normally. Worst case scenario, you burnt out the old fuel pump by running it dry.

it could be a fuel pressure problem, or the none return valve is not working. (regulator) could even be a blocked filter in the fuel line. worst case its the pump.

fuel may contain dust which block.

hi there, first off you need to make sure the voltage is good, then make sure your spark plugs are firing properly(all 4) then take off the fuel line coming out of the fuel rail to the tank(not the one coming into fuel rail from fuel pump) and swing the engine and make sure the fuel is flowing. Once you can verify that everything in the above is operational then we can continue with the diagnosis of the car.

Worst case scenario - fuel filter, spark plugs and /or leads, distributor cap, coil pack or fuel pump may need changing.

Might be the fuel pump on the way out..

Change the coil.then check for spark also change the H T Lead from coil to distributor

you might need to put a non return valve on the inlet pipe from the tank to the carburator

Check the fuel filter it may be blocked.

thers a oil psi senser that wont let the fuel pump run at low psi when the car worms the psi gos down ,the fuel rely only runs the pump for about five sec as a primer then the oil psi senser takes over thirs a plug righi behind the oil fliter for the senser ,un plug it and put ajumper wire across it as a test ,you may need a oil pump

Could be coil or ignition module starting to fail
