Fuel Pump Not WOrking On Obd0-obd1 Conversion
 

Just Install a b16a2 into a 91 civic si.....

TO my knowledge and testing everything is working but the Fuel Pump...

I have come to the conclusion that the main relay is either not grounded or supplied by 12v

to be more exact when i turn the ignition to the on position the fuel pump should prime the lines but nothing happens

i may have the harness F%&Ked up.
i just ordered an obd0-0bd1 jumper from www.rywire.com

this could fix the problem (i hope)

like you figured, fuel pump gets power from the main relay. if you wanna test it, you COULD run the fuel pump right off the battery, then crank the engine to see if it'll start.
