I purchased a 2000 honda civic si that had a ls darton sleeved block bored out to a 2.1L. The car had an aftermarket accel stand alone, cp pistons, crower rods, msd inline fuel booster, msd ignition, 680cc injectors, stock fuel pump, turbo, ect. I bought the car with a blown motor and desided to swap the stock motor (99 si b16a with about 3000 miles on it) back in. When I turn the ignition on, the fuel pump keeps on running. On all of my other honda's the car primes for about 3 seconds and than stops untill you start the car. I was told not to worry about this, but after about 6 miles, the IAC (EACV) - idle air control valve went out. The other problem is that when you turn the key on, it sounds like the fuel is flowing straight through the regulator and back to the return line. I tried to replace the evaporative emmission control solinoid (on top of the fuel rail, injectors plug into it ), the fuel relay, and the fuel pressure regulator without any change. I checked the ecu wiring, and from what i could see the pump wiring is all stock.
Can anyone tell me what is causing the pump to keep running and would this cause any problems in the future? thanks
