Hello, here is an important update to my post on mas control unit operation.
When checking for power from mas to fuel pumps (from terminal 2 at mas);

You MUST have the following at mas connector plug;

Terminal 1 - battery voltage, not fused
4 - ground
10 - battery voltage, in start/run, from ignition with ignition ON
12 - 10 volts, start signal, while cranking engine only
16 - 4.5 volts, td voltage signal from EZL ICU while cranking engine only
21 - 11.5 volts, fused, from OVP Relay, with ignition ON

If any of the above is not present a good mas unit will not supply power to the fuel pumps. The engine will either not start or will start but will not run. Do not replace mas unit just because it fails to power fuel pumps. (using a proper guage jumper wire from pins 1 and 2 should only be connected while the battery is disconnected otherwise it will arch and pose a danger being close to the battery) once jumpered, connect the battery to test the pumps only, pumps should run with jumper in place. NEVER DRIVE THE VEHICLE WITH JUMPER IN PLACE!.

I think that of the above, lack of battery voltage at terminal 21 of mas unit from the OVP relay would be the most common fault. Repairing or replacing OVP relay should solve the problem.

I apologize for any confusion or misinformation from my previous post
