Ever since day one,I've been trying to get my wife to let the glow plugs warm up before starting. Still to this day she doesn't do it.I've given her a hard time about this to the point where I just gave up. With all the glow plugs going bad out there,is my wife helping to make ours last longer? Should I have been thanking her instead of getting on her case? Technically it starts everytime she trys.  Is she doing wrong by this engine,or is this ok? |

Most of the time down here it's not cold enough for them to need an extended heat cycle. Only on those days when we were having 20 degrees during the day was I getting an extended glow plug lamp. Usually it only barely flashes, you have to be watching the light to see it. Based on the forecast, you may get a chance to use them Friday. . . |

mine are used here in the cold and snow covered land that is Pennsylvania. I could not even get it to start with out waiting a few seconds for them to cycle. In the summer when I first got the Jeep I could hardly catch the GP light. I started to not even bother to wait in the summer and start it like a gasser and it always started fine. Now is way different. |

My CRD used to start at -20deg F without any issue. Lately, if its below 35deg F, it takes forever. Battery has been ruled out (12.7 volts no load, 12.0v with glow plugs cycling, and 10.2 v when cranking). I threw in some new glow plugs and got a new glow plug harness on order. One wire showed .3 ohms resistance while the other 3 shows virtually none on my digital multimeter. One wire also had insulation worn off on it and I decided my time was better spent not repairing the harness by splicing in new wire for it from each plug end. When plugged into the harness measuring resistance showed each plug at 1.3 ohms (normal spec is .7 to 1.2) but with glow plugs out and cleaned (they were soaked in oil from my manifold/valve cover oil leak) out, they all meausered within normal spec. If anybody wants them, they are yours for free. I just replaced them to rule them out but won't know for sure until Libby is put back together. |
