i have a 2000 s-10 2.2l non flex fuel that i just replaced the fuel pump and filter on but im not getting any fuel tothe rail or from the pump. i replaced the ecm 1 and ecm b fuses and checked the relay that seems to be good. at the harness on the pump i am getting .02 volt reading on the brown and black aftermarket wire and im getting 1.86 volts off of the purple wire. that doesnt sound correct to me. can someone please give me some insight or other suggestions on what to try. thank you!

purple to fuel tank is the fuel guage sender

gray and orange jump together at oil switch or relay socket see if pump runs then and if the truck starts

do you hear the pump run for a couple seconds with key in run position?

if not then you got bad pump or relay, or bad wire or connection

or missing ground at fuel tank hanger/pump or relay

Did you drop the tank, or remove the bed? Check the ground at the rear of the bed, on the frame, driver side. It powers the fuel pump.
