The fact that there is a new fuel pump doesn't tell me whether or not there is adequate fuel pressure at the rail. I also would need to know whether or not the Digifant-II computer is pulsing the injectors. So, get yourself a fuel pressure tester (you can borrow it from any major parts retailer) and a Noid light (less than $15 at the same parts retailer). Fuel pressure should be about 44psi and the Noid light should flash brightly.
Please perform those two tests and get back to me with the results so we can continue.
Looking forward to those test results.
