    Mitsubishi Pajero 2004: Why is it slow to start?

    Mitsubishi Mitsubishi Advice Mitsubishi Pajero Mitsubishi Pajero Advice Mitsubishi Pajero 2004
    It takes three to five turns of the key my 2004 Mitsubishi Pajero 3.0-litre to fire in the morning. After that it starts easy, even if I leave it for four or five hours. I have changed the fuel filter, the spark plugs, the injectors and I have had the computer checked. The fuel pump doesn't hold pressure overnight, but three mechanics have told me there is ample pressure once the ignition is turned on. I left the car overnight on a 45-degree angle to the front to ensure fuel can't drain back into the tank, but I had the same problem. I have spent over $500 on it so far which is why I haven't changed the fuel pump or regulator as I can't just keep replacing parts without knowing they will fix the problem. What do you think?

    It’s either getting too much fuel or not enough during the cold phase. If it’s getting too much fuel it’s likely to be due to worn fuel injectors that are leaking down while the car sits overnight and essentially flooding the engine. Although you say you have replaced the injectors, you don’t say you used new parts, so I would still look there. It could be though that the temperature sensor that tells the computer that it needs to boost the fuel for a cold start is faulty and the message is not getting through.
