Re: Where are the spark plugs located on a lexus ls 400?
There are on the two sides of the engine block as with most v-8 engines; however, they are down underneath a wide assortment of engine components. You will have to do a bit of disassembling to get to them.

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.
The spark plugs are located in well in the valve cover, remove them one at a time with a deep 5/8 good quality spark plug socket 3/8" drive on a 12 inch extension and a like sized ratchet. Remove the spark plug boot from the plug with a twisting motion side to side with the spark plug out remove the spark plug wire for that cylinder from the distributor cap and match it by length to the new wire in the spark plug wire set, make sure you get the closest one in length to the original wire, this is important. In stall the spark plug back into the valve cover well and attach the long plug boot to it in a twisting motion, use a little silicone grease on the inside of the boot to ease installation, it is supplied with the wire kit. Repeat this for each cylinder and match the individual wire lengths as you go as close as possible to the original wires. PLEASE NOTE: IF YOU FIND OIL ON THE PLUGS OR WIRE BOOTS THE VALVE COVER GASKET IS LEAKING INTO THE SPARK PLUG WELLS AND MUST BE REPLACED.
Either fuel is dripping into cylinder after the ign is turned off or you have carbon built up on the valves or plugs and it it hot and ignites the air fuel mix when you turn ign off pull spark plugs and inspect.
if you refer to spark plugs wet with fuel , 1st check for ign coil have spark , if good, then check engine compression , if under 100 psi , thats the problem.

the starter is located in the valley under the intake manifold. you must remove the intake to access the starter. its a pretty involved job. when reassembling take your time and make sure that every wire is plugged in and every vacum line is connected.
