Thank you Tom, that looks exactly like what I need to test, specifically where they mention "Solenoid coils are more likely to exhibit shorts when they are hot".

Let me see if I understand what they are saying to do to check primary injectors. Let me know if this is right:

1. Run car long enough to get hot and heat soaked
2. Remove power to ECM
3. Pull Injector 1 fuse from fuse panel on passenger end of dash
4. Test resistance between the right side(closet to nose of the car) of the fuse plug-in ........... and the 8 injector connections on the ECM connector A(A8,A3,A2,A7,A1,A12,A13,A18)

Looks like I'll need to extend the wires on my volt-meter to reach that far.
