1981 fiat spider 2000 fuel injection trouble

[macawlover70]

Ok, I have a spider with 71000 miles. Fuel injected that I just got from a friend who knows little about it. I have traced the "not starting" problem to the fuel injectors not getting a signal with a noid tester light. I ran through the checklist for the combo relay and the ecu from the diagnostic manual and found wire 85 which I think is a ground is not grounded but found the whole thing a bit confusing. I opened up the combo relay and found alot of rust in it and the ecu connector has some bent contacts but not so bad that I think they are affecting the connection. I'm going to replace the combo relay and if that is not it, the ECU. Any advice and help would be appreciated. Also, Where is the inline fuse located?
