put a space heater pointed torwards the engine for 30 mintues before you start it. To test glow plugs. Take a test light. Pay attention. Put the lead that has the clamp on the + side of the battery or something 12v. DO NOT try and cycle the glow plugs. Leave the key off. Take the test light and touch the end of the glow plug were the power would go. If the test light lights up bright. The glow plug is good. If the light is dim looking. The glow plug needs replaced.
