PGM-FI Main Relay
Just dropped a H22 in a 92 Prelude SI, got rid of all the codes for the CEL only two (6, 21), tried to hit vtec @ 5000K rpm and the car died, the Back-Up fuse in the under-dash fuse box blows, i've replaced 4 already with the exact same 10A fuses, and it still does the same thing? i try to go and start the car, and it blows.. I've looked in the Helms manual downloaded online, and I believe its the same fuse as the PGM-FI Main Relay... Any help please, Thanks

did you wire the vtec solenoid and pressure sensor correctly?? sounds to me like when vtec hits something is shorting out or grounding out that isnt supposed to, and then blowing the ecu fuse.....check your wiring....
