If no fuel it moving, then the pump is not running. If the fuse is good then that only leaves the pump.

dropped the tank, installed the pump,took it for a test run,drives good, No problems yet,
now I have to figure out the issue with trany, drives good-sometimes i have to drop to 3-2 for take-off
and while driving some times the tach goes to 4-5 as if in idle,
thank you for all your help and ideas, i'll keep in touch with trany issues,
ROBERT *.

If it feels like the trans is slipping, check the trans fluid. Also when was the last time the filter was changed.
