I have replaced Distributor cap, rotor, wires, and spark plugs in my 2000 Oldsmobile Bravada AWD smart track. To replace one spark plug I had to collapse the steering column, but everything went O.K. Did you marked the wires?. Did you reconnect them in the firing order? The fuel pump is located In the fuel tank. Remove the fuel tank and take the fuel pump out from the top. This is part cost $300 and need some skills to be replaced. The fuel filter it is directly in front of the fuel tank. Another one is incorporated with the fuel pump.
I have 2K bravada. Make sure you have serviced your transfer case with the "blue" GM Auto-trac II fluid. The "encoder" motor is a common failure item also. Unplugging it at the transfer case should cause the "service smart trac" light on dash to appear. This tells you that probably the encoder controller is good. Only buy the GM/Delphi/AC Delco motor, or you'll be changing it often. Try "thepartsladi" on eBay!
Probably a bad transfer case encoder motor. Common problem on Bravadas. Also make sure your transfer case uses only "blue" GM Auto Trac II fluid. Flush once after driving a week with "blue" if you don't find "blue" fluid when origianlly checking. Just temporarily plugging a new encoder motor to harness should get the light to go out. Other less likely problem could be bad AWD control module or fuse.
definately repair that wire. now keep in mind that that particular wire is called a shielded wire and you need to be clean and careful when you repair it. make sure it is water tight and protected. this wire is for the abs wheel speed sensor and with no reading, the abs is inoperable which will affect the awd. the abs and smart trac work in conjuction with each other to help you remain stable. cheers.
Probably the transfer case encoder motor. Unplugging it at the wiring harness should make the "service awd or smart trac" light come on. This will tell you the awd controller module is probably OK. Common failure item to Bravada's. Try "thepartsladi" eBay store for lowest price motor, beware aftermarket!!! Also make sure transfer case fluid is "blue" GM Auto-Trak II only! If not bllue when checking change twice after driving for a week with blue fluid.
If youre talking about wheel hop when turning at slow speeds with only the info you have provided I would guess it has smart track AWD and this is normal, How ever if you have push button 4x4 controls your front drive axle could be locked in, in that case have a garage check it out...
drain the transfer case and check for metal particles in the fluid, there also may be debris bigger than that, try the fluid change in any event then if that doesn't do the trick you will have to overhaul the transfer case, this is a standard transfer case used by light duty trucks and SUV's based on a truck chassis, not the viscious drive type used bt passenger cars like Suburu
