As for the no start, while your in there check the pins for the ignition module connectors. It’s possible one got bent over when it was reconnected. It’s easy to do.

Far as trouble shooting the fuel pumps goes, checking the current draw at the diagnostic lead (red wire jutting out of the big wire loom near the windshield wiper motor).

Each pump draws 4-5 amperes each for a total of 8-10A with both pumps working..

With the ignition switch OFF you can configure your VOM for measuring current and connect the meter between the positive terminal of the battery and that diagnostic test point.

If the reading is only 4-5 amperes, then you have part of your answer.
