I did a h22a swap on my 91 accord. Everything is good all the wiring and plugs are connected. But my main relay won't work to switch on my fuel pump. i checked and I'm getting voltage coming in but none out. I disconnected the relay and powered by hand and it works. I pumped the pins and the fuel pump works. Just don't understand why it won't click over when th relay is in. Help me out

 

So you have sprak? Confirmed how?

What ECU and Dist are you using?

Sounds more like you should be testing the INPUTS to the relay and not the relay.

Where did you mount the main ecu ground?

 

Either a bad relay or possible ground missing to MFR.

good luck
