Good day folks.
As you can see I am brand new here although I have read many threads pertaining to previous trouble I had with my little Uno and honestly appreciate all the efforts of the community to help each other and help total strangers.
I have a 1994 Uno 1100 Fire ( the License model apparently assembled here in South Africa by Nissan). I suspect the engine is the 1108cc version.
My little Uno has had many troubles but I usually sort them out quit fast, but this time it has me stumped and my funds are running low due to experiments to find the fault.
In summary here is a list of events that lead to my Uno not wanting to start.
Initially I noticed the idling would become erratic, sometimes revving a little faster than normal for a few minutes and then coming back down to “normal”.
Then came the new problem of intermittently cutting out at stop streets or while driving if I did not get into gear fast enough to start accelerating again.
Sometimes, when I would park for a while and try to restart it, it would only crank the engine without starting...after a while (perhaps a few minutes) I would try again and it would fire, only to idle for about 90 seconds and then cut out again. It would idle as normal, and then quickly loose speed and just die.
At this stage, I checked for loose HT cables and the distributor cap. Found the 4 contact points inside the cap to be almost 100% worn away so I replaced it with a new one, and replaced the little rotator as well just for good luck.
This did not solve the above mentioned symptoms. I used the car one more time to town and back and after parking it in the yard I can not get it to start anymore.
When I turn the ignition key, it will crank the engine at “regular” speed for about 4 times and then would follow a “difficult” crank as if it is battling to turn the engine. Like in the olden days when you had to start those old Lister water pump engines with by turning it by hand...or when the battery is flat etc.
A auto electrician gave me a second hand ECU Module to test out and it did the same. He could not say for sure if that particular module was actually in working order, so I went further and bought a brand new one and still the engine swings 3 or so times fast followed by some difficult swings. About a year ago, the engine would also not start and just cranked without starting, I replaced the ECU Module and it took instantly thereafter until now. I kept that old broken one all this time (who knows why), and even tried that one as well. When that one is installed, the engine swings continuously normal without the sluggish difficult cranks, but does not fire up as it did back then.
I also set and replaced all 4 plugs, still no joy.
I did not fiddle with the timing or carb or anything, it kind of went like this all on its own.
Please, if there is anybody out there who could point me in the right direction with this one, I would sincerely be in great debt to you.
Warm regards,
