Always problems with these old EFi conversions I'm afraid.... My advice would be get an OFAM ECU from Boost Monkeys and then you can at least see what's working and what isn't and as someone said above now's a good time to go full ZT too!

But if your sticking with what you have then have you checked continuity between the CPS plug and the EDIS unit?
Fuel pump you can hear prime even in tank ones so if that's not priming then check, fuse, relay, voltage at plug, etc.. etc.. basically as it's all 25 years old there could be a break in a wire or a poor connection just about anywhere, you'll need to spend some hours with a multimeter going through it all
