94 SHO MTX STILL NOT STARTING

[Garichette]

died while driving (no fuel pump prime)relay control, fuel pump, and pcm have been replaced. i know the pump works because i was sold the wrong relay control and it ran constant but still no start. got the right one today but now back to no prime and not even a sputter of life with the pump on or off.. what could be causing this?? please help!

link to my other post and wires found still don't know if it has anything to do with no start ideas? http://www.shoforum.com/index.php?threads/the-sho-must-go-on.130916/#post-1438647

also will not give codes..

Is it a brand new pump? I can't tell you how many brand new pumps would not suck through the new sock. As soon as I put a little air pressure to the tank, it forced the gas through the sock and to the pump. Fixed about 3 or 4 new pump installations that way. Those little gerotor pumps are good at pushing fluid but not at sucking air.

it is a new pump but its not priming with the correct relay control box. it just ran constant and was pushing fuel with the auto one they sold me but no spark.. i have checked and sanded all the grounds could it be the harness? which pins should have power? going to try old ccrm tonight

Did you get an answer to what those cut wires go to? My first priority would be to figure that out.

You get a 111 code or nothing at all? If the test won't work at all then the fuel pump isn't the main problem

Here is an example of what can happen with a new pump -http://www.shoforum.com/index.php?threads/fuel-pump-not-powering-up-code-95.130894/
It is a long-shot, but it shows what is possible.
