03 wont start 41,000miles

ok only have 6.6v at inertia switch. 6v at fuel pump. looked at fuel pump relay and only have 11.98v on one of the three smaller legs socket into fuse panel. why would i lose 6v?? ZERO pressure at fuel rail w/gauge. did check large connection under drivers seat looked brand new. checked voltage pk/blk blk wire at fuel pump comnnection 6v. no codes.
truck was running no issues. switched drivers never restarted.

Swap out the fuel pump relay.
I believe the A/C relay will replace it as a temp fix.

new pump and strainer orderd today..will keep ya up dated. PROBLEM FIXED!! It was fuel pump. I only had 6.4v at pnk/blk and ground because you only have 12v for 2 sec...then 6.4 yel/wht is for fuel gauge.

noticed that little squigley hose on top of tank is rotting...i mean bad to the point that it might be a reason that my pump failed. When I looked into the old pump I could see a black tar and I bet that is where it came from. So for $1.00 replace it while your there.
Thank for all your help and this is a great forum!
