The solenoid resistor is getting power from the battery. When I checked the resistance from +B to the No. 10 and then the No. 20 terminal, I got readings of 3.4 and 3.5 ohms respectively. My Haynes manual says this reading should be between 2 and 3. Would a half of ohm make the difference of my injectors firing or not. How exact do the tolerances need to be?
