well... i originally had an issue of my vehicle randomly dying during drives. i switched out the ignition switch for a USED OEM part... but because these parts/vehilces are so old, i am not sure if i got a bad ignition switch or my fuel pump is going out.

the shutting down while drive is less frequent (dashboard stays on now, when it dies). i have a NEW cap, rotor, wires, plugs, ignition coil, fuel filter... i never had this issue before the swap, but my vehicle hesitates when i give it gas now... sometimes.

where do i find an OEM replacement fuel pump (that will not effect my gas mileage)

 

What car and set up?

It's rare for our fuel pumps to fail. A common cause of engine stalls is the ICM/igniter unit. You may want to have it tested.

 

94 honda civic sedan (EG) JDM d15b... p28 ECU...

the igniter unit is new... i got it from advance auto parts.. then again.... i never had this problem before until i swapped this out. lol. i can test both the ICM and igniter unit right?

 

Make sure all the igniter unit wires are clean and tight. Have an auto parts store test it.

Also test the coil. You'll find a diagram in the FAQs sticky for resistance testing the coil.
