hard to start, rpm jumps and feels like running out of gas
2000 Chevy blazer cranks a couple times before it will start. When you get going about 40-50 mph the rpm start going up and down and feels like its going to run out of gas. I've replaced the starter,alternator,battery and I need this for work I've been told I need change fuel filter but afraid its the pump. I don't have money to go to garage I need help to try myself to figure this out.

welcome ! sounds like the fuel filter needs to be changed ! a fuel filter wouldn't run no more then $20.00 at Advance or Auto zone ! I would go that route first before changing the pump ! best of luck ! I have a 99 blazer and a filter for mine at Advance cost about $15.00.

check the fuel pressure at the fuel rail ! there is a small valve you screw a tester on to check the fuel pressure and volume ! if it seems low then it could be a dirty fuel filter ! if it's still the same once you change the filter then it could be a bad regulator !
