Cold start injector

Anybody know how many ohms I should be getting when testing a cold start injector? Is it the same as the other 8 (15-17)? Also anyone know how to test the cts & cold start sensor? 87 305 TPI.

3.5 ohms is acceptable. I'm not sure what the acceptable maximum would be, but suspect anything over 10-12 ohms would indicate a problem. The CSV is not controlled by the ECM, but is powered by the Cold Start Control, so currents can be higher without risk of damage to the ECM switching transistors.
