No fuel from tank
I am unable to get fuel delivery from tanks to engine in normal operation. I can however get pumps working with jumper wire to them. It will start with ether but not stay running on it's own. Could this be a relay or something in tfi thing ?

If it starts on ether but not stay running on it's own then you have spark and it is not the TFI module or the Ignition system.
First check to see if Inertia Fuel Shutoff needs to be reset by pushing down on the button on top.

If no help you need to ground pin #6 of the EEC Test connector with key on and see if the pumps run.

That got the pumps running. now should it have pressure at the check port ? only has a little fuel or do i need to give it some time to build . I left it on for a minute or so and had some fuel but not a steady pressure stream.

Do you have two tanks?
If so do you get the same thing on the other tank.
Can you hear the selected pump in the tank run while pin #6 is grounded and the key on?

This is the second time today I have been ask this question.
I will tell you what I told him:
If the pump will not run for one second when you turn on the key and will run with pin #6 of the EEC self test connector grounded with the key on then yes there is a good chance that the PCM is bad.
Other possibility's are:
The wire from the self-test connector pin #6 to the computer pin is open, not likely.
The PCM is not grounded, has happened a few times. (small wire at the NEG [-] post of the battery not making a good ground at the body ground junction or post)
The PCM is not getting 12 Volt Power, has happened a few times.
There are pins pushed out in the PCM plug or are very corroded this has also happened.
But most of the time it is the PCM that is bad.
