I need to replace my fuel pump in my 1996 Lexus LS 400 and I need to know how to get to it and procedure of taking it out and putting in a new one? Email me at [email protected]

First, please post your question only once.
There is NO INERTIA SWITCH on your vehicle.
The only thing to check is FUSE #1, which is a 20A fuse that provides power to your EFI control. If that is good, check for voltage at the fuel pump when the vehicle is turned on. If it has power to the fuel pump but the fuel pump is not running, replace the fuel pump.

run fault codes and replace faulty sensors. have a fuel pressure . Check injectors for correct operationtest done on the fuel manifold to test fuel pressure regulator. pump and filters/

my be the fuel lines or jets

The fuel pump is inside gas tank behind the back seat unscrew the only top that's there and it is inside the gas tank. You will have to remove your back seat to gain access to fuel pump. Fuel tank is located in trunk. No need to take fuel tank down.

Hi, I answer one like this just before.
There is no external fuel filter for this model Lexus, the fuel filter is mounted in the fuel tank attached to the fuel pump.
Thanks

yes you do, here are basic instructions for any in tank fuel pump. also remember to replace the fuel filter as well or warranty on pump is voided.

Your fuel pump or fuel pressure regulator are not supplying constant fuel pressure. Too much or too little is causing it to kill. You can pull the vacuum line from the regulaor and check for gas. If there is none, you need a pump, it is weak.

yes, no problem

You will have to remove your back seat to gain access to fuel pump. Fuel tank is located in trunk. No need to take fuel tank down.
