| Post subject: | Slow Starting |
When I don't drive the CRD for a few days or more, it seems that the engine is cranking more than usual before it starts. This only happens after a few day delay. Once started and run, the following starts are exactly like I have come to expect. The battery is fine, the glow plugs seem to be working based on the dash light, I get no codes, and the engine drives fine & gets good mpg. Any suggestions? |

did you check for air in the fuel head? or the actual voltage of the battery after a few days of sitting, you might have a small drain. |

check fuel head for air, also when did you last change fuel filter? The filter assembly area is the most likely cause, followed by the glow plugs. |

Of course, the fuel filter. I should have thought about that. Its been in about a year & 1/2 but only 18k. I completely forgot! THANKS! |

You need to update your sig line. We have no way of knowing whether you have a lift pump, which would rule out air in the filter head. |

Two areas of concern: Leaking fuel filter head = heater plug or priming pump Deteriorated oem red-top or lead-acid battery not holding charge due to normal security alarm and other module drain - if battery voltage is reduced, as from sitting several days, engine will take longer to start. F.e., #2 son replaced slow-starting gel-cell with lead-acid, restored starting - when driven every day, KJ starts well - KJ sits for several days, slow starting resumes - replaced lead acid with new red-top gel-cell, KJ starts well whether driven regularly or left sitting for a week, measured pre-start voltage is always higher than with the lead-acid |
