lexus sc300 , i installed a new fuel pump, and the ecu to the fuel pump, now the good thing is the car starts up on it own now, but the bad thing is when i push the gas it still studders and then go. could somebody help me on this one

 

 

nobody has an answer?

 

Try this mod. https://www.clublexus.com/forums/sho...d.php?t=291189 The 12v fuel mod will bypass that computer. Maybe the computer is bad. If your getting low voltage it will studder and sometimes die. You can always test the voltage with a voltmeter at the pump.

I just did this mod today works perfect, never been happier with my car.

 

r u pullin any ecu codes or did u bypass sensors?
