Resistance of coil winding in injector
The resistance between the terminals on each injector should read 2-3 Ohms. If winding is open (infinite resistance) or shorted (no resistance), replace injector.
Resistance of series resistors
The series resistor should measure at 5-7 Ohms each. With ignition on, supply voltage of 11-12.5 Volts must be present from terminal 43/1 and terminal 43/2 of series resistors to ground.
