Ok My Buddies Got A 91 Civic Si, With A JDM B16A Running OBD0 Using A PW0 ECU.

The Fuel Pump Wasn't Working So We Hardwired It To See If It Was The Pump Its
Self, It Works When You Hard Wire It So We Checked The Main Relay And Used Three
Different Relays That We Know Are Good And Same Problem, So We Hooked Up The
Voltage Meter And Where Getting Power To All Of The Wires On The Harness That Plugs
Into The Main Relay Except For The Wire For The Fuel Pump, Its Getting No Power, So
We Found The Problem. For Some Reason Theres No Power Getting To The Yellow/Black
Wire For The Fuel Pump On The Harness Thats Plugs Into To Main Relay. So My ? Is Does
Anyone Know Why He's Not Getting Power For The Fuel Pump Wire For The Main Relay??

 

Anyone?

 

alternator sylenoid fuse sounds stupid but thats it, in your under dash fuse box i had the same problem with my ef lol

 

You mean main fuel relay?

 

imageshack that SOB...its not clickable and my eye ***** are having a hard time reading it without a magnifying glass

 

no i dont mean main relay, main relay controls fuel not power to everything its the alternator sylenoid fuse trust me on this one i tried like 39 main relays cuz i thought i kept blowing them then i talked to ef king, he told me to check the alternator fuse sure enough changed it fired right up it sounds rediculously retarded but that was the problem
