LHS 1997 3.5 V6 issues
 

Hello.

I have problems with 97' LHS. After I turn the key, all of the control lights turn on, I can hear a pump that injects gas, and when I turn the key to 'start' position the 'Brake' control light turns on, and nothing else happens. There were moments when I just left it for 10-15 minutes, after that I went in, turned it on, and everything was ok, next time it turned on, but soon turned off again (idle speed problems) and then the problem continues. I have detached and re-attached the accumulator, and battery in immobilizer key was changed.

Does anyone know what may be causing the problem?
