Where is start inhibit relay location on 99 arnage

Check the passenger side fender/bulkhead. There should be a relay panel there, look for the inhibit relay. This is your starter relay.

Does it have a vehicle theft deterrent system ? Try putting the gear selector into neutral to see if it will start then , if it does the park neutral safety switch could be the problem . Looking at a wiring diagram an testing the starter electrical circuits with a DVOM - digital volt ohmmeter would be the proper way to diagnose , not guessing an just replacing parts .

Starting System The starting system consists of the following:

• battery
• ignition switch
• transmission range (TR) sensor
• inhibit relay
• anti-theft relay (if equipped)
• starter motor

Starter Motor
The starter motor:

• is a permanent-magnet, gear reduction, 12V DC motor.
• has an integral starter solenoid.

Inhibit Relay
The inhibit relay:

• is a mini ISO relay.
• switches power to the starter solenoid to engage the starter motor when it receives a START signal from the ignition switch (11572).

Transmission Range (TR) Sensor
The TR sensor enables the circuit to the inhibit relay in the PARK or NEUTRAL position only.
Anti-Theft Relay (If Equipped)
The anti-theft relay:

• is a normally closed relay.
• is grounded by the anti-theft system, which opens the relay contacts and disables the starting circuit.
• PINPOINT TEST A: THE ENGINE DOES NOT CRANK CONDITIONS DETAILS/RESULTS/ACTIONS A1 CHECK ANTI-THEFT SYSTEM OPERATION NOTE: The four different anti-theft indicator operating states are OFF, ON, flashing once per second and flashing once per three seconds.

Have you checked the low and high pressure switches ?

Should be 1 in the trunk and also 1 under the rear seat

Know a fellow with a Bentlet He basically has to keep battery on atricle charger most of the time or it won't start. You don't always get what you pay for!

the latch is in front of the engine to the right side of the car right above the headlight.

Unfortunately they make this propriatary information and require their own computer to do so. I wish that I had better news. You can call Alber's Rolls Royce in Zionville @ (317)873-2360 and the service dept. there may be able to assist another professional (you) in getting the secretive codes. They have always been good to me.

the starter is located under the intake. also the fact that the radio plays doesn't mean batt is good.

Remove the rear covers from the head light unit. Put these cover in the bin. After 2 days the head lights will be ok? I had this problem with my Arnage and it's never happened again. I have had this one now 3 years
