Installed fuel pump and sending unit on 94 park avenue now fuel gauge doesn't work it was fine with old unit. Now it reads empty

Buick gas tanks are shaped so when full they take a while before the gauge comes off full. After 1/2 then the gauge will move towards empty quicker. When on an incline it will show more gas than is actually in the tank, so when you're cornering, it's reading will be indicating the moving level. I wouldn't worry about it

Takes gas good while setting hit a hill or make a left turn dies or bogs like it aint getting enough gas

Not being funny but do you run it with near empty tank ?
Blockages in the fuel line can cause this sort of problem, does it cut out going down hill ? Either way, check your fuel flow and fuel pump. When a car is run to empty, junk and dirt is sucked up from the bottom of tank and can foul any of the injectors and lines.
Hope this helps...

Check engine light comes on and gas gauge goes from it current position to empty going down the road

It sounds like you have a bad wire or connection. Did you have the fuel pump changed? The mech may have been a little sloppy. I'd bet the problem is near the top of the gas tank where the pump is.

What's the easiest way to change the spark plugs and my gas gauge bounces around alot it goes from full to empty. my 4wheel drive wont engage either

jack it up, use jack stands. take off the front wheels, and go in through the wheel well to get to the spark plugs. Gas gauges on every blazer is freaking crazy. mine acts up when it`s at a 1/4 tank. Park up hill it shows more, park down hill, it shows empty.

To much trouble to replace, unless you have the time and money to replce the sending unit.

When going up a hill my gas gauge goes to E. and gas light comes on

Easy solution, it's your gas pump, if it's not bad already you might need a new one in the semi-distant future. Maybe 6 months to a year, it's also that your gas is measured by a Styrofoam like piece that floats at the top of your gas and goes down as the gas does, so it could just be the fact that the tank is strangely placed and when you go up a hill it thinks it's really low when it in fact isn't. Not a big problem don't sweat over it.

No power when going up hills, tries to overheat when going up hill. air conditioner only works when on high. gas gauge says full when tank is empty.

Run scanner for trouble codes, some auto parts stores will do this for free,check coolant level, check fuel pump level,  you will probably have to pull it from tank.
