I'd have to make sure battery has a full charge and battery connections all good. You can use digital multimeter across battery posts, everything off, the generic spec for a full charge is around 12.6 volts. If the battery is down, get it charged up. We can't do any testing if the battery is down. On further testing, you can take starter motor off, lay it on the ground. Hook up jumper cables properly from charged battery to starter motor, at the least, the starter motor should spin and kick out the drive gear. If it won't do both, then I suspect the starter motor has a problem. I only mentioned the starter motor because you heard a whirring noise, maybe that noise was the starter motor spinning but not engaging the flywheel, for some reason.

If you have an engine light on you might ask autozone to read the code and tell you what's wrong. It could be that your spark plugs are worn out. If the spark plug gap is too great then that could cause stalls due to lack of ignition.

Sounds like low coolant

you need to replace your switch the theft system is activated with the key maybe try putting the key close to where it goes

Have you found the fuse box or you just don't know where it is? It is located in the air filter box.

If you mean the knock sensor, it is on the side of the engine near the center. It can be screwed into the engine block or the cylinder head, depending on which engine you have.It has only one wire. Bank 1 is by the firewall.

you need a mechanic to look into this, shorted wires can create damages to the computer. Shorted wires also burns the wires until it is cut-off and will not function properly.

Is it a driving noise or a noise only when the motor is running with the car stationary??If its a driving noise then it could be a wheel bearing otherwise its an auxillary drive Ie alternator or pas pump etc

collapsing bottom radiator hose indicates blocked radiator cores would be time for a new radiator after you again flush out the cooling system completely have the radiator shop fitting the new radiator do the flush as they know how to do it properly

Wow, I just went through the same problem and guess what it was a clogged converter and a bad oxyegen sensor. The garaged fixed it up for me by putting an eco converter on it and a new O2 sensor. I have a 2003 Chevy Impala,V6 3.8 engine. Good Luck!!!!

2003 Chevrolet? Model? The best place to start is your owners manual. Your manual should have a description of the fuse boxes and the relay center in it. Test the relay, make sure the flasher relay connection is sound or just replace the relay to see if your intermittent is resolved.

what are you talking about what hose on what bit of equipment and what does the hose do?

where do you hear moaning sound coming from ? Under the hood in engine bay ? That could be the ABS pump motor ! maybe going bad . service traction control light on ? DTC'S - diagnostic trouble code or codes stored . Have codes checked .

I would go to Wal-mart and buy their best battery.. have them check to make sure the car is charging.....(if the battery happens to go bad... there is a Wal-mart everywhere and you can still get a new replacement battery at 3am)

Looked it up in Chilton's, confirmed in http://www.obd-codes.com/trouble_codes/

P0481 Cooling Fan 2 Control Circuit Malfunction

Each fan will throw a different code. See 3 fans listed for your model. Here's a link for the wiring schematic: http://www.chiltonlibrary.com/content/images/WD/GM/014/WD_GM_014788.pdf


Best of luck.

There is a relay (Headlamp relay ) left I/P fuse block . Do you know how a relay works ? Test B+ voltage an ground before replacing . Do you know how to do that ?
