im doin an h22a swap into a 93 prelude and everything is done except for the fuel pump isnt turning on when you cycle the key over i was wondering if the reason for this was because of the PGM-FI main relay or if there was sumthing else that could cause this to happen please let me know as soon as possible id appreciate it thanks

 

Sounds like the main relay. Check the relay fuse first to make sure its good then check into the relay

 

where is the fuse for the main relay located? 93 prelude

 

double check the ground on the intake manifold or thermostat housing
