How the naphtha pump of a Blazer 98 is changed

Good morning, someone could inform me how the gasoline pump from a Blazer 2.2 of the year 98 is removed and where the fuse of it would be,
I tell you that from one day to the other I do not start anymore, check and arrives current well and when I take out the naphthac hose nothing arrives, so I assume that the pump is broken

Well, it is inside the fuel tank. Verify the manual to see the fuse.

Investigating a little more I saw in the diagram that the pump relay is controlled by the ECU, it is the Ecm B fuse of 20 amps and 15 amps, it would also be good to verify if there is a spark in the bugies and pulse in the injectors, if there is none of this then verifies the state of the crankshaft and tree tree sensor
