Marc has identified the ECM Pin outs for fuel injector resistance here....

Measuring Fuel Injector Resistance with the Plenum in Place

Marc says:
1. The primary fuel injectors have a common connection at the Inj 1 fuse. Resistance measurements can be made between the fuse connector and the individual connections on ECM connector A.

2. The secondary fuel injector resistance is measured between the ECM A connector and the secondary relay connectors. Remove the secondary relay connectors for easy access to the pins.

As Franke suggests.....
