Where is the starter located? I have removed the air intake and battery etc. I still do not see a starter!

It will start when cold, and after driving and then parking, the starter will not turn over? Replace your starter/solenoid.

WARNING: WHEN SERVICING THE STARTER MOTOR (11002) OR PERFORMING OTHER ENGINE COMPARTMENT WORK NEAR THE STARTER MOTOR (11001) , BE AWARE THAT THE HEAVY GAUGE BATTERY INPUT LEAD AT THE STARTER SOLENOID (11390) IS "ELECTRICALLY HOT" AT ALL TIMES. BE SURE TO DISCONNECT BATTERY GROUND CABLE (14301) BEFORE SERVICING STARTER MOTOR .

REMOVAL & INSTALLATION

Fig. Remove the starter electrical connections, noting their locations

Fig. Location of the two starter retaining bolts

1. Disconnect the negative battery cable.
2. Detach the air-flow sensor assembly connector and remove the breather hose.
3. Remove the resonator retaining nuts and remove the air intake hose and resonator assembly as required.

NOTE Use care when removing the air cleaner cover because the air-flow sensor is attached and is a sensitive component.

1. If equipped with Active-ECS suspension, remove the air compressor as follows:

1. Detach the two electrical connectors, from the compressor.
2. Disconnect the air line at the compressor.
3. Remove the three mounting bolts, securing the compressor to the chassis.

1. Raise the vehicle and support safely.
2. Remove the engine undercover.
3. Remove the heat shield from beneath the intake manifold on the 1.5L engine.
4. If necessary, detach the speedometer cable connector at the transaxle end.
5. Detach the starter motor electrical connections.
6. Remove the starter motor mounting bolts and remove the starter.
7. The installation is the reverse of the removal procedure. Tighten the starter mounting bolts to 22 ft. lbs. (31 Nm).
8. Connect the negative battery cable and check the starter for proper operation.

Although the LS 400 is a great car, the engineering could have been a little more "consumer oriented," when it comes to repairs.
I'm sorry to be the bearer of bad news, but the starter is in the middle of the engine, underneath the intake manifold. This means you must remove the negative battery cable, empty the coolant, remove the air intake assembly, the throttle body, all of the vacuum lines, hoses etc. and then the intake manifold. The starter is located under the intake.
If you are a "back yard" mechanic, you can do this yourself. It's not very dificult, just extremely tedious. It also doesn't require any special tools, just the basics, such as a metric ratchet set and open end wrenches. It would take a pro about 5 hours.
Good Luck!

The starter is located beneath the intake manifold, disconnect the ground cable at your battery, remove the cover covering the intake assembly, disconnect fuel lines and any hoses and wiring connectors from the fuel injectors and any sensors,remove all the bolts from the intake asembly,and lift it up to gain access to the starter. You will have to replace the intake gaskets before reassembly. This is a fairly easy task it just looks complicated.

Also remove the air inlet tubing to the throttle body and whatever else may be in the way of lifting the intake. You dont have to neceesarily remove the intake just remove enough stuff lift intake up and support it up then replace your starter, its dry beneath the intake, no oil or coolant to mess with (time +/- 3 hours).

I hoped this has helped (remember rated this)

starter is located behind the motor under the intake manifold, to replace remove the battery cable & air filter box and remove 2 15mm bolts that go through the bell housing into the starter then get under the car and remove 4 10mm nuts & bolts that attach a plate from intake to the block then remove 1 more 15mm bolt holding starter in and pull it back then nose first down then remove 10mm and 13mm nuts on starter solonoid removing cable and wiggle it out past the half shaft and vualla its out

The starter is located under the intake manifold near the firewall, remove the battery terminals, remove both electrical connectors on the starter,remove the two 14mm bolts, there is one from the rear and from from the front, the starter can be removed through the top but the air intake hose and air filter have to be removed.

Follow the positive battery cable ; it will lead you to the starter. if you are in the process to change it the procedure is below

• Disconnect the negative battery cable
• Remove the air intake duct and the air cleaner housing assembly from the engine compartment
• Disconnect the battery cable and the solenoid terminal connection from the starter solenoid
• Remove the starter motor mounting bolts and detach the starter from the engine

The starter is located under the intake manifold on this engine.

The starter relay is on the drivers side of the engine compartment behind the air filter housing under the fuse box cover
