Hello I am new to the forum... I have a 2003 zx12r... I have an idle issue and loss of powe.r tach will barely climb past 9k.. what I have done.. calibrated and check resistance of TPS. It checks out. Just replaced complete charging system,all voltages correct... I have not put a fuel pressure gauge in yet but suspect it is a fuel pressure issue. The pump sounds funny.. I removed tank and pump the inside of the tank clean.. my main question is should it hold pressure in the line to the throttle bodies.. there was no residual pressure in the line when I removed it... any help would be greatly appreciated... Thanks in advance....
