You might need to run a ground wire from the engine to the battery and make sure it is the same gauge as the positive lead. The newer electronic components especially fuel injection units need this to operate correctly, a ground to the frame is not sufficient. What will happen is they will look for ground through all the other wires, this could potentially burn out other components in the vehicle. If this is not the problem try an MSD Dyna Force starter.
