If this is an older vehicle, with carburetion, a ruptured diaphragm in the fuel pump could cause this.
If this is a fuel injected engine, these engines use plastic fuel lines under the upper intake manifold. These lines become brittle with age and sometimes leak causing fuel to run down into the crankcase. If this happens you have to replace the lines, relatively cheap and easy fix.
reset what? this makes no sense. sorry .
An engine diagram for a 2005 Chevy Trailblazer can be found in a Chilton's Automobile Repair Manual for that make and year of vehicle. Chilton makes many repair manuals for all kinds of vehicles.

The starter is bolted to the engine by two bolts which makes it very easy to change, just remove the bolts and drop the starter down until you can remove the wires from it, it is a good idea to remove the negative battery cable before starting the job to prevent arcing the wires to ground.
Assuming it has a 4.3 engine, the oil sending unit is located under the hood, in back of engine, drivers side, next to the distributor. It is difficult to see and get to. Removing the distributor makes it accessible.
Need to know what year it is, it makes a difference.
