Pretty sure it's the fuel pump:
Turned the key to the run position, ICV is vibrating
Inserted a wire on pin 85b of the relay, with the key in the run position see 12V, key in the Start position see 1.5V so looks like the DME is trying to pull it low and turn the fuel pump on
Shot some starting fluid into the engine, catches and fires just fine
Pulled the fuel pump fuse and cleaned the contacts, fuse itself was fine, reinserted, no start

Is there any other possibilities before I replace the pump?

Thanks for all the help, I know there are hundreds of threads on this subject, but many of them go well off track and it takes hours to get to the right one...
