Not much detail there, but sure sounds like your "start" fuel pump relay is working, but the "run" relay isn't doing its job.

could you have a vats system not working. maybe when you swapped the computers.... also check with a spark tester if you are losing spark. and hook a fuel pressuer guage up to the fule line. which one are you losing? cause you know you have air. those 3 need to be there for fire to happen
