i doubt the power steering pump is breaking your belt. im going to assume youve been using defrost more since its getting colder outside. maybe the ac bearing is bad and when the clutch cycles it on the belt is whats screaming and ultimately is going to wear down and break

You have two options: 1) remove the negative cable for about 5 minutes. 2) you can remove your main relay/fuse. Good Luck

I HAD THE SAME PROBLEM WITH MY CAR. 93 LS 400. THAT WOULD BE YOUR FUEL FILTER OR THE FUEL PUMP GOING BAD. TRY CHANGING THE FILTER FIRST. THE DEALER TRIED TO CHARGE ME $980 TO CHANGE FUEL PUMP.

Doubtful it's an intermittent electrical problem. Far more likely you've got a wheel speed sensor issue. Since VSC gets all it's information from the ABS system, start by pulling the trouble codes. I bet you'll see an ABS code. Read this post

Now, I'm not saying this is a fact, but my TH700R4 trans did that very thing, wouldn't come out of third. And with no 3rd it won't go to overdrive. I rebuilt the trans and found the overdrive drum was all scarred and caused the limp home thing to happen, third gear was as high as it would go. I suggest you have the trans checked out by a professional trans shop. As for it being a bear to start, that's a faulty temperature sensor. If it's not functioning, the computer doesn't know to put it into cold start mode, which increases the throttle speed and puts more fuel in the engine for starting when cold. Like a automatic choke system in earlier vehicles.

There are 1 or 2 large fuses in the main fuse block near the battery. 100 amp and 150 amp usually. Pop off the clear plastic tops and check those. Most times those will require separating the block to unscrew the bolts that hold them in.

Good morning,
There are a few possible reason for your leak:
1) check your rack for leaks by the dust boots

2) check your power-steering reservoir return line for leaks.( over time they tend to split and/or crack)

3) check your radiator for milky appearance (if this is your issue - lots of work ahead).
