I recently swapped an F22B DOHC into my 5th gen prelude. Once i break in the clutch ill be installing the turbo setup. I am going to be starting it up NA for this first time this weekend, however i noticed yesterday when i got the battery hooked up and got power to the car, that the fuel pump is not priming. I've herd that Walbro's are pretty loud and i dont hear a thing. My pump worked fine the last time i drove it before i pulled the H22. So last night i went ahead and took it out, and put my stock pump back in.
(which probably has been knocked around and battered a little bit over the last 6 months). I still did not hear the priming. The main relay is clicking on, so i dont think that is the problem. It is a pretty straight forward install, so i dont see how i could have made any errors, but i guess its possible. I wouldnt expect that the pump would be bad from the factory, so if anyone has any idea what could be the problem please let me know. thanks

you should connect the walbro to a battery and see if it works if it does your problem is somewhere alse and yes walbros are loud i had one.

 

how exactly do i go about connecting it to a battery? apologies, electronics pwm me.

 

power / ground on the battery
power / ground on the pump

= complete circuit

 

problem solved. I didnt have the main ecu fuse connected by the temp switch.
