New to this forum, and having a major issue. My grandson fried the heads on his 99 impreza outback 2.2. We found a complete 98 legacy 2.2 with less miles so we did a swap. The upper wiring harness on the intake was substantially different so instead of splicing a million wires, I elected to change out the upper harness. Now that is done, after installing engine we tried to start it, and although it turns over fine, we are not getting fire to the injectors. Fuel rails are full and has plenty of pressure. The cooling fans and fuel pump cycle constantly when the key is turned on. Is there anyone out there that can shed some light on my dilemma? Only wires that I had to splice when changing out upper harness was the injectors, and they are connected correctly and tight. Help !!!!!
