Let me give it a shot. What actually is the problem?
1) You can lock/unlock the car from the trunk but not from either driver/pass doors?
2) You change the pump and the problem remains?
3) You use a mityvac and all doors locks as expected. That means all the pods and the lines are holding vacuum and the problem is electrical.
The lock/vacuum works on a very simple principle. When you lock, a switch tells the pump to suck/vacuum. When you unlock, the switch tells the pump to push. The signal is not getting to the pump from both doors. Check the connectors to the pods in both doors. I cannot remember exactly but it is a 3-wires connector and there is a yellow wire which is the sensing line. It is a 0/12v ( not sure which voltage) signal to the yellow line to lock/unlock.
