Fuel System or Starter Problem 2002 Chevrolet Blazer..Please Read
 
Im just going to start a new forum because its such a crazy issue.. Bout a year ago my fuel pump had to be replaced.. we put a used one on but it fixed the problem.. had to crank it twice before it fired up tho... couldnt get the filter off to change it when we changed out the pump. A few months later it wouldnt start... Killed the battery trying to get it to fire up. Changed the plugs and wires, and ran a fuel cleaner through it and it started. Little bit later we changed the MAF sensor because we ran the code on the check engine light.. it was using a lot of gas and running poorly. It was a major improvement. It ran ok, still having to crank a few times before it started.. then it started to randomly die if i slowed down and i had less than a quarter tank gas and wouldnt start unless i undid the battery for half an hour.. so we cut the line to fit another filter on. Started running premium gas through it... started on the second crank everytime, ran great. This morning at the gas station after it was quite low on gas it wouldnt start.. then all of a sudden it wouldnt even crank.. just clicked. I called for help and pushed it out of the way.. then it stared turning over again but I only got a few tries before the battery ran too low to crank. I had my mother meet me with cables and we attempted to jump it but ddnt have but about 15 minutes to work with it before she had to get me to work.. Tryed a few times and had to give up... What do yall think? I love my blazer but here lately am ready to give it away!!;) Can a pump be weak?- It has required several cranks since this repair... But im so confused w the disconnecting the battery and it starts... ughh!

Have you done a pressure test on the fuel system?

Should read 60psi with the key on and about 55psi with the engine running and should hold atleast 50psi 5 minutes after it's been shut off.

no.. what will that tell me if it isnt getting enough pressure? pump kicks on.. could it work but be weak? you got any idea why the battery disconnect would work? and what about its starter glitch today??
