do you have them on the right side of the engine? they are labled L and R and thats looking at the engine from the back (like left side of car / right side of car)
most single 1jz i've seen dont hit till after 4000-4500 rpm anyways...
lag is relative.. on the stock cams/ the powerband is limited.. add some cams, and you'll think 4500 is perfectly fine..
acutally the ecu has no control over the fuel pump power (besides main relay).. The ecu does connect to the fuel pump relay to trigger low voltage to the pump, rather then high voltage.. its constanly at high voltage..
Make sure the ecu is turning on..
