    Fog lights...before you dig to deep...check the wire harness plugs for the fog lights in the front wheel wings...I had the same issue with one light out, checked continuity on the bulbs, ground and voltage to the lights ...found there was no power going to it, followed the wiring harness to find a plug inside the front wing disconnected or loosely connected. Same as you with the brake light, sometimes I go to deep before checking the simplest solution ...lol

    Very cool systematic analysis of each circuit. I enjoyed that.
    I also enjoy hearing you speak. The words you choose to speak are rare these days! Very neat to hear.

    Great stuff Todd, another 'winning' vid.
    If you haven't chased all the earth points and given them a clean up, it might be worth doing even as good preventive maintenance. Top tip: Fit new bulbs everywhere! 😊 Sort of pulling your leg on that one, but I'm sure you know where I'm coming from. It might be worthwhile too, to keep the battery on charge all the time, if you don't already. All obvious things I know, still no harm in mentioning it all the same. What I would strongly advise is when you start the car from cold let it heat up, the quicker the better as it's got the old CIS and those systems tend to operate very rich prior to max engine temperature. Doing that just may avoid some bore wash.

    When you work on electrical plugs try using a 2mm oil passage brush to clean out the female sockets. I put it on a drill and clean out each socket, it gets out all the corrosion.

      The body is the easy part… I just pay someone to do it. The important and interesting stuff is underneath it :). It does look bad, but I’ll be happy when the car is mechanically solid and reliable. Then I will sort the bodywork :)

  • @jonathanmorgan1649
    @jonathanmorgan1649 Год назад

    Todd, i swear we must have the same car. i recently did some vacuum leaks checks, and some AFR adjustment, and I've found that when the fuel relay is connected, i get a no-start condition. If I take it out, the car cranks just fine. If i jump the 30 & 87 pin on the fuel relay, the car starts and runs just fine. So, maybe check that one too and just replace. I've seen on some threads that the fuel pump is actually supposed to run for a second as soon as the key is in and put to position 2 or 3, but it doesnt prime if the relay is dodgy or failing. It sounded like yours IS doing that, but may just check..

    • @jonathanmorgan1649
      @jonathanmorgan1649 Год назад

      I want to add here that: when the fuel relay is connected, "sometime" i get a no-start condition. it's intermittent. sometimes the car will crank and work on the first try, and sometimes it just wont crank at all. sometimes it'll crank once, but then never again. very strange, and perhaps you have some ideas on that.

    • @MrToddgibbs
      @MrToddgibbs  Год назад

      Hi Jonathan - strange. My issue appears to have been dirty contacts on the fuel pump relay. No issues since cleaning…. But you never know for sure. Maybe yours is same issue OR dirty internal contacts inside the relay…. Search on rennlist for how to clean. Good luck

    Nice job! Glad to see you tracked it down. I still say if/when you are ready, replace wiring harness and 14-pin connector. A fresh harness and connectors may eliminate many electrical gremlins. Check/clean all grounds, as well, if you haven’t already.
