Put a gauge on the fuel rail or use your gauge and see if the pressure drops more than 2 psi per minute. Next test the fuel injector resistance a stock one should be 11-14 ohms, but they all should be near each other. This will tell ya if you have a bad solenoid in one of them.To start the fuel injection process, the ECM sends a signal to close the poppet valve, stopping the flow of fuel through the injector body and trapping fuel in the passages leading to the injector tip. As the injector arm continues the downward stroke, the trapped fuel in the injector passages comes under extremely high pressure. 4. Write down the resistance (Ohms) value recorded on the multimeter for each fuel injector. Don' forget to write down what cylinder that reading belongs to. 5.
