Kia Troubleshooting Questions? Ask a Mechanic
are you watching a misfire counter? what codes are curren
year make and model? how did you determine the injectors are shut off?
Based on information from various sensors, the PCM measures the fuel injection amount. The fuel injector is a sole- noid-operated valve and the fuel injection amount is controlled by length of time that the fuel injector is held open. The PCM controls each injector by grounding the control circuit. When the PCM energizes the injector by grounding the control circuit, the circuit voltage should be low (theoretically 0 V ) and the fuel is injected. When the PCM de-energizes the injector by opening control circuit, the fuel injector is closed and circuit voltage should momentarily peak.CAUTION: If an injector connector is disconnected for more than 46 seconds with engine running, the PCM will determine that the cylinder is misfiring and cut fuel supply. So be careful not to exceed 46 seconds . Turn the ignition key off and wait 10 seconds to restore normal operation.SPECIFICATION
Coil Resistance (ohm)13.8 - 15.2 ohms at 20 °C (68 °F)
if it has no pulse its either a wiring issue or a bad driver in the pcm
the injectors should stop pulsing if misfire is detected, that is the emergency function of the engine management to prevent damage to catalytic converters, I would focus on primary ignition plug wires and plugs, and if that does not help a compression check
this a 2.7?
all data shows a cable set? I guess its a cop have you swapped coils?
I would focus on the 1 and 5 injectors before moving to the crank sensor
