Well, if your question is "Will a MAF computer work on a SD engine?" the answer is no.

IIRC, MAF showed up on trucks in 1994.

my problem

Here it is. I pulled a '94 302 and replaced it with a rebuilt '89 302.
My high pressure pump was not priming, so I wired it direct with a toggle switch. I now have sufficient fuel-pressure to the rail, I have strong spark on all 8 cylinders, but my injectors are not firing.
My last hope is replacing the ecm.

Check to make sure you're getting 12V at the injectors and that the ECM is powering up. Also make sure you have the plug wires in the correct firing order. The 94 probably has the 1-3-7-2-6-5-4-8 order while the 89 (if it's from a truck) has the 1-5-4-2-6-3-7-8 order. It should at least sputter, though, with the wrong order.
