    I RECEIVED YOUR ANNSWER AND I THINK YOU MAY BE CORRECT BECAUSE THE IGNITION KEY IS NOW ABLE TO BE REMOVED WHILE THE CAR IS RUNNING. I DID REPLACE ALTERNATOR BUT I WILL CHECK WIRING. WHERE IS THE ECM LOCATED?

A faulty altenator or voltage regulator will do this, bad wiring or connection to ecm, or faulty ignition switch.

I have a 2004 Nissan maxima and as I was driving it, the car shut down.No power brakes, steering etc.It would crank but not start


check the alternator. may not be charging. car will run until battery dies and than it will die, since things like computer and other components are not getting power. also cam sensors may cause this, but usually the service engine soon light will light up, if sensor fails.

Why does the battery light and brake light flash on & off?


If it can be determined that the oil leak caused the alt. to fail prematurely it should be replaced at no cost to you.If it is obvious and there is alot of oil on the alt.I would file it under the warranty.

Hatterasnc,

You're alternator has gone bad and the vehicle was running on battery power. The "clicking" sound is your now dead battery that does not have enough power to turn over the starter. You might also want to check your power steering pump for leak. This is a know problem with early LS400s and will most likey be the cause of the alternator failure. I just dropped $1050.00 to fix the very same promblems you have.

change the drive belt and have the voltage regulator in the back of the alternator checked out and also check for any draws on the car anywhere cause this can cause the alternator to over charge trying to keep the battery charged up
