Run compression test and report results.

This code means random multiple misfires, and could be as simple as a bad ignition module, or can be timing component has "jumped time". If your engine uses a timing belt, you should be able to tell if it has broken by turning crank a little bit back and forth to see if cam is turning (valve cover removed). Most parts stores will test the ignition module for free.

Under the hood next to the washer fluid reservoir you will see a black square box with a philips head screw in each corner. Unscrew them until the top is loose (they don't comeven completely out) lift the top up and replace the old filter with the new one.

its probably were it connects to the sensor that lets you know but if its in four wheel drive and still works when light is off you shouldent have nothing to really worry about

Are you talking about the ubec (fuse panel) under the hood?

If the problem is that the brake lights will not turn off, the problem is most likely the CHMSL relay. An easy check is to take the cover off the fuse block mounted on the driver's side fender well and swap the fog lamp relay with the CHMSL relay. If that fixes it, just get a new relay for the fog lamps and you're good to go. Note, my 2002 s10 does not have fog lamps, but it still had the relay populated in the fuse block.

Possible warped cylinder head, or cyclinder head gasket.

This is not a full answer, but a tip on an easier way.to get to the pump. Instead of removing the gas tank. Just pull the bed off the truck! I guarantee that it will be easier. I did this on a 2001 S10 and it took less that an hour to remove the bed. Remove the spare tire, and the tube that the tool to lower the tire goes through. You will need to unplug your tail lights under the back or the bed on both sides. There is also a grounding screw for the tail lights on each side that needs to be removed. Remove the screws that hold the gas tank filler hose to the side of the bed - right by the filler cap. Remove the tailgate (to make the bed lighter). Follow the frame down the length of the bed and you will find the bolts holding the bed on. There should be 6 or 8 bolts. My S10 had 8 bolts and my son's full size Chevy PU had 6 bolts (go figure?). Then just lift the bed off the truck. We did my S10 with 3 people and it had a camper shell and rack on it. My son's full size truck was lifted off with only 2 people. I would suggest 4 people however - one on each corner to make it easier to lift and control. Replace the pump as described above and then you can start the engine to make sure everything works before setting the bed back on. NOTE: The fuel pump grounds back with the tail light ground. If the engine doesn't start right away, try grounding the wire back by the tail lights. It works like a charm. This is an especially nice way to do it if the gas tank is full! I spent 18 years as a professional mechanic and this is one of the slickest, least known tricks I have come across. I wish I'd known about it when I was wrenching for a living! Cheers!

You have a shorted hot wire to ground. You did say what the fuse was for.

There are several flat bearings in it that would cause a noise like this, if they have locked up. If your going to replace them, you might as well rebuild it. Beware through. There are a lot of some parts that have to go back in it. in order.
