My 1999q45t start up but alternator wont turn fan clutch wont turn crank pulley turn battery light on brake on

Answered on another page.

Do you have a bad starter? also check for loose or dirty battery cables on both ends of cables as the starter does take a lot of pull and a dirty or loose cable won't give it the power to start but will let the lights work.

That's the sign of a dead battery or a failing alternator

Combination of brake and battery light mean the alternator is not charging. after you wait for a wile the battery recover some power and will run again but as soon the power drop below 9V the engine die. Test the charging system and replace the alternator
Good Luck

sounds like your fan belt is slipping ! hence that why the battery light comes on because alternator isnt turning or turning slowly and your power steering pump wont be turning also ,,,making steering difficult ! fan belts can be adjusted at the alternator i think thanks :)

Nissan truns the brake and battery light on when there is a charging issue. When you say it wont start does that means it craks or no? If it does not crank I would attempt to charge the battery then try to start it and check the charging system.

Hi:
I am not sure what was the reason why your battery needed replacing, but if it was dead, I am guessing your alternator wasn't charging it?
Take off the serpentine belt on your engine, and check to see if all accessory items turn smoothly, to include the power steering pump, AC, alternator, and the idler pulley. If any of these wont turn , the car won't crank either. If you totally remove the belt, you can see if the car will start, and go from there, but don't let it run too long without the belt.

It is the harmonic balancer, ie. pulley. It is a two piece--with rubber between the two. It will, especially if belt dressing or other lubricant has penetrated it, slip. I just ordered a new one online for $70. It is a fairly common problem.

drain engine coolant.relieve belt tension .and remove the drive belt.remove upper fan shroud.remove fan or fan and clutch assembly.remove water pump pulley and coolant hoses from water pump.remove water pump bolts.then remove pump from engine.pay attention to bolts location because they are different lenghts.clean water pump gasket mounting surface dont scratch .or pump gasket wont seal and leak .apply sealant to water pump bolts.install water pump with new gasket.if gasket paper put a sealant on it.torque water pump bolts to 30 ft lbs.if you got a 2.2L engine torque water pump bolts to 18 ft lbs.install coolant hoses on pump .install water pump pulley.install fan and fan clutch assembly.install the drive belt .and the upper fan shroud.fill the radiator with coolant.then run engine to check for leaks.WARNING AS A SAFETY PRECAUTION REMOVE NEGATIVE BATTERY CABLE SO CAR WONT BE CRANK BY ACCIDENT. ALSOOOO DONT FORGET TO TURN OFF RADIO FIRST BEFORE DISCONNECTING BATTERY SO YOU WONT LOSE YOUR RADIO CODE.

check the drive belt, pulleys and the timing and have the alternator checked and also the crank sensor
