Which series ems and PN# are you using? I have had the 30-1300 EMS for almost a year and a few days ago, I had a similar issue with the MPI relay. Mine as clicking erraticaly and the EMS would not connect properly. After about an hour I found the culprit. My pin connector for lambada in had wiggled loose and was not making complete contact with the EMS pin. Once I fixed the loose connection the problem was gone.

Same thing happened to mine. Could be if you unplug the ECU with out disconnecting the battery. Swapped in one from my parts car and it worked great.
