It sounds like you're on to something there.  That's one of the first 
things I check on an L-Jet car with a start-and-die condition. 
Opening the AFM with the key in the RUN position should activate the 
fuel pump.  But you say that jumping the pump to run all the time 
doesn't help...hmm.  Well, it sounds like you found at least one 
problem.  This is where I'd start to suspect an ECU failure, but you 
say you already swapped it with a known good one (I honestly don't 
remember if the fuel pump cutoff in the AFM is dependent on the ECU 
though).  Have you checked the injector grounds?
