What is the function of the fuel pump and ignition coil pack for my 92 ls 400 lexus


The fuel pump pumps the fuel from the fuel tank under pressure up to the fuel rail and injectors.
The coil packs provide a electrical charge (about 40,000 volts) to the spark plugs. It is this charge that makes the spark plug spark.

Unfortunately the only was to get to the tank is to lift the car high enough to drop the tank down enough to unhook necessary lines and electrical connections to the pump. Once you lower the tank, a few rubber line connections and electrical plugs. Mechanical level 1 - 5, this would be a 3.5

FUEL GAGE DOES NOT GO UP ALL THE WAY


HI, this is a malfunctioning sending unit that is located inside he fuel tank. this sending unit, transfers a Resistance signal to the gauge, in return, allowing you to see how much fuel is in the tank. if this mechanism becomes corroded or, damaged, this will cause the symptoms you are experiencing.

This damage is usually caused by fuel deposits left behind overtime. the modern day fuel we use can destroy sending units because of all the detergents and, nitrogen cleaning agents put in the fuel at the refinery. this is goo for cleaning out the rails and fuel injectors but, it usually can hurt the sending unit mech at the same time.

The fuel gauge sending unit is attached to the fuel pump Assembly. you will have to remove this assembly from the tank to replace it. the tank has to be lowered as well.
