I have a 97 Chevy Tahoe 4x4 350 vortech, what
it just a basic tools. find the filter and see what size it is.
crawl under the truck on the driver's side, follow the fuel line from the fuel tank to the filter(shape:cylindrical).
make sure the line has no pressure. you should pull the fuse for the "fuel pump" relay, then start the engine and allow it to stall.

I don't know what testing you've done? How long since a tune-up? Any applicable trouble codes? To check codes yourself, at the least, you need an obd2 code reader.
In the diagram, see the pink wire at ignition coil, that is primary voltage to coil, with key on, use a test lite and see if there is voltage? If no voltage, that circuit is fuse protected, I believe ecm 1 fuse, under hood fuse block. You need to do some testing and tell us what you find?

94 chevy k15 blazer problems
White smoke coming from the exhaust system is a sign of an oil system problem. If you did not have this issue and no other signs of an oil system problem, I would agree that the sending unit may be the only issue and needed to be changed. However, since you have been told that smoke is coming out of the exhaust and the car is acting up under load (going up a hill) it is time to take action and make sure your oil pump gets checked ASAP. Before you dive in you may want to check the oil on the dipstick to see if it looks/feels thin or watery. If that is the case, you may have other issues like water in the oil system from a bad head gasket - water looks like bubbles on the dipstick. If oil of the wrong type was used, the problem may be that the oil is too thin to work properly and needs to be replaced. If the oil looks fine and feels like its got the right consistency, the problem may just be with the oil pump. You didn't mention it but have you noticed the vehicle running hotter than normal? If so, this is another clue that the oil pump may be failing.
Whether the oil itself appears to have issues or not, you still need to have the pump checked. .
