    Help please! Defender Puma intermittent ignition issue.

    I hope I've posted this in the correct spot!


    Hello wise forum.

    For about a week now I have been having an intermittent issue with my ignition, where I turn the key fully on, and absolutely nothing happens.
    I then try again and it works perfectly... or it doesn't. Either way I haven't been stuck yet because I always manage to get the car started but it is increasing in regularity and in the amount of attempts required to get it going.

    I'm not sure if this is related or not but the issue started the day after I dropped a spanner in the battery box causing a second or so of sparks.

    Thoughts?

    I would be checking the 12V trigger on the starter motor(the small wire that tells the solenoid to engage the big wire).If they get oil/dirt etc on the connection becomes poor.
    I doubt the sparkles had much to do with the problem.

    The ignition key barrels play up a bit as well on some.
    My son replaced his on the Puma a while back.

    Battery terminals OK?

    They can sometimes be tight but corroded between the posts and lugs and cause all sorts of intermittent issues.

    Happened on one of our vans recently,the fault only reared its head when high amps were being drawn from the battery,that is when starting the engine.

    I'm with Andrew, sounds like a solenoid issue.
    If you don't like trucks, stop buying stuff.

    Thank you people for taking the time to reply.
    It's some time since I posted the question and my thanks is coming very late.

    No, not yet.
    I've been dealing with the now constant issue for awhile but I'm going to have to wait till I get it to Graham Coopers in Sydney in a couple of weeks before hopefully getting it fixed.
    I tried looking at it again today but am shamefully admitting I couldn't find the starter motor even armed with a google image. Useless.

    I had that issue of trying to find the starter motor when I was looking to connect an ignition wire. I gave up and connected somewhere else instead. Its next to the front passenger wheel from memory. I don't have to worry about these things anymore though my daughter's boyfriend is an auto sparkie and a land rover nut so she's under strict instructions

    Ahh... I thought it might be there. I'll have another stab.

    I need a daughter I think.

    Resurrecting this thread. I've been having the same problem for about a year now....mostly on hot days too, but if I pop to the shops, sometimes (maybe 1 in 30 times) when I get back in the car I turn the key and nothing happens....the dash lights are on but there's no click, no engagement of the solenoid. I wait for 30 minutes and it fires right up like normal.

    I never lock the car and am wondering if it's therefore an immobiliser issue or if it's the ignition switch. Either way I'm going to try getting a new switch and asking the lads at KLR to bypass the immobiliser for me.

    One of them suggested that having an Ultragauge plugged in might not be helping but yesterday when this happened, I removed it and the car still wouldn't fire up until 30 mins had elapsed.

    It's doing my head in. Any advice or input welcomed.
    Bobby
