Hi there. The code for your vehicle would be the code 15 that you are having trouble with. The code 15 states that there is an intermittent power cutoff. Measure voltage with a digital volt meter to pin 1 wire on the ECM (computer) connector. If there is a 12 volt reference, then check the pins 20, 40, and 60 for continuity to ground. If The resistance is less than 5 ohms, then the ECM has failed and needs replaced. If all the pins read a good resistance, then there is a loose ground either from the engine block to the frame or from the chassis to the frame. If you need further assistance with your vehicle not starting, then seek out a professional, such as one from Your Mechanic, to help you.
