Hey all, so I have a 2000 Ford Mustang that I just replaced the engine, with a 3.8L v6 from an 01 Mustang, the previous engine was a 3.8 as well. We got th engine in and it’ll crank but won’t start, spark plugs are all good but we have no fuel pressure, the pump wasn’t working fine before the engine swap so I’m not thinking I think is the issue. Any advice?
Cranks burn no start no fuel pressure

Test for key on power at the trunk mounted IFS switch. Use a KNOWN good ground. What to do next depends upon the test results.
Did you remember to re-install the ground strap from the left hand motor mount to the frame rail?
But after a motor swap I would double check the CCRM/PCM ground. There are larger black wires with a white stripe that goes around the battery to a larger round single pin connector.
Double check there's key on power in and out of fuse F2.34, F2,2, and F2.8
