Question about GMC Sierra 1500
Hi, that's possible but first check the ECM fuse and use a test light to check for power to the injectors on the red and white wires. The computer uses a number of sensor inputs to calculate the injector signals required. If these signals are not available, the computer cannot send the appropriate injection metering signal and will usually set the engine light. Is the engine light on?
