Hi I have an 8822re pick up I’m not getting any power to the fuel pump when I turn the key to the acc I hear the main relay click but the maf sensor does nothing even if I manually move the flapper to make the points touch I still don’t hear the fuel pump I’ve replaced the pump since I had the bed off any help would l be much appreciated it will run only with starting fluid did not use much just enough to test to see if it would run it sat for about 3 years even if I jump it out at the diagnostic still don’t hear it I jumped out the open circuit relay and still got nothing

 

the fuel pump doesn't run with the key at "ACC", nor is it supposed to. your truck as originally equipped didn't have a MAF, either.
