Here's what I did:
- with FI assy, ECM disconnect and fuse out: checked each FI pink feed back to the ECM-1 fuse to check continuity; checked ea FI colored wire back to ECM to confirm continuty
- with FI assy disconnected, checked resistance across each injector's connectors; res registered 11-9 to 12.1
- with FI assy connected and ECM-1 fuse in, fuse blows when power is turned on whether if ECM is connected or not
I'll try what you suggest on the wire voltage check and additional injector checks and let you know what I find
