1996 406 hard starting

Discussion in 'Peugeot 406' started by Clive Turnbull, Feb 9, 2004.

  1. Iam a UK based autotech and I have a customer with a 96 406(petrol)
    which on occassions is very hard to start from cold. He has had it into
    main dealers for diagnostic test and they say there is nothing wrong.
    Anyone else had similar problems? Thanks Clive

  2. May sound a daft reply but is the battery up to full strength ie all cells
    holding their charge. I've had no start/poor start 'cos of a dieing battery.

    Depending on ECU behaviour when cold, may indicate a loose coolant temp
    sensor connection.

  4. No, turns over a treat and has had a new battery.

  5. Faulty sensor would show up on a diagonistic.
    I had took my v6 into Cooksons (Macclesfield) They stripped the injectors
    and found a defective "coil" replaced it. All was fine afterwards Total cost
    £250, and a car that worked.

  6. I think it was Cooksons he took it to. I think I will have to go one
    cold morning and pull a plug lead off and make sure it is sparking from
    the word go. If it is I will have to asume I should be looking for a
    fuel problem. Many thanks Clive

  7. "You do need to be very precise with the symptons and required test
    conditions when explaining things to "them" at Cooksons, likely come from
    th' 'ills. But with perceverance it will sink in and they might discover,
    like mine, the cause of the problem.

  8. Couldn't agree more!!

  9. Replace the Coolant Temp Sensor and customer says it is now "acceptable"
    Good enough for me.
    Thanks all
