Hey fellas,
I recently did a B16 1st gen swap into a 91 Civic Si. And I'm not getting any fuel to the fuel lines. I checked the fuel pump wires for power w/ a test light and got nothing. What can it be? Fuel pump relay? There is no fuel pump fuse for it (that I can find in the fuse locations.) Help. All the sensors are hooked up except vtec.


When I'm using the PR3 ecu (JDM DOHC) I get the engine turning over but doesn't run.

When I'm using the Stock Si ecu I get a buzzing sound coming from the main relay. Still doesn't run.

I checked both ecu's on another 90 Civic and they both work and the relay also works in the other car.

Any Clues?

Did you hook the ground up by the thremostat ? Just wondering, anyways test you main relay out. There is a way to test it out to see if its working.

 

common problems are the main relay (you should be able to hear a spring click from the lower lefthand side near the drivers door) when you turn the ignition to on position. The other can be a bad ground wire... im not sure how it works for a civic si but try following the ground wire it should go all the way back to the rear of the car in the trunk area and grounded there ... make sure that it is ok.
