Ls400 Fuel Pump Resistor Bypass. You can use a paper clip jumper on the diagnostic connector, between the fp and b+ i think it is terminals to bypass the fuel pump. We also include wiring up the toggle switch for dual electric fans, because we’ve removed. After verifying it is working correctly, if the pump is still not getting 12.5v, i would bypass the fuel pump resistor. Does anybody know when to replace the fuel pump resistor on my 1991 ls400 ? All data i can find, including the numbering on. Even if the ecu was not powering up the fuel pump relay the fuel pump should still run because it looks like the relay is set to bypass the resistor when starting, and also does that for. This video we cover the 1uzfe sc400 ls400 12 volt fuel pump ecu bypass mod. So now i have to figure out how to bypass the fp ecu and run 12v directly to the pump which is how i got the car to run. After running my car at 8 psi and achieved 324.5 rwhp. Before changing the fuel pump, i bypassed the resistor and nothing changed. This is pretty much the. This fuel pump upgrade diy tutorial applies to 1990, 1991, 1992, 1993 and 1994 lexus ls400 models. Now that i have changed the pump, the car stalls.
