Check primary fuel pump.

Check fuel pressure with key on.

Check fuel pressure while running with primary fuel pump fuse pulled. Car should die once it reaches 176 degrees on the coolant.

Let car cool down 30 minutes. Insert primary fuel pump fuse, pull secondary fuse. Start car, note how car runs only on primary.
