Nord ignition problems
Hi all,
Lately I've been having some strange problems with ignition. When I try to start my engine in the morning it fires up and then dies with a cough. Okay, that's normal but then it happens: On the next attempt the engine is completely dead! Sofar I've replaced the distributor cap, the lead wire between the coil and distributor and the spark plugs. At some point I even replaced the coil with one I've had lying around for some years. Since there was no change and I lacked equipment to cut the tie wraps I put the old one back. Somehow later during the day it just seems to come back to life and I can eventually start it. Once running there's no trace of anything being wrong. I can cut it and restart it without any sign of problems, even after several hours. The next morning it's back to square one... I've taken the whole thing apart this weekend. Cleaned up everything but still haven't found the source. The strangest thing happened when I removed the spark plug from cylinder 1 to see if I had a spark at all: with the plug removed the engine seemed to come to life, with the spark plug put back in it was completely dead again. I verified this behaviour, three times in a row. That's the point where I replaced the spark plugs and thought I'd finaly found it, until this morning... Anyone have any clues? Please, I'm at the end of it.... Gordon Gordon Giulietta 1.8 '82 GT Junior 2.0 '75 GT Junior 2.0 '74 (project) |

We had the same problem with our Giulietta when I rebuilt it the first time. Eventually I traced the fault to the ignition switch. It was energising the solenoid so the engine turned, but not energising the coil, so no spark HTH -- Catman MIB#14 SKoGA#6 TEAR#4 BOTAFOF#38 Apostle#21 COSOC#3 Tyger, Tyger Burning Bright (Remove rust to reply) Alfa 116 Giulietta 3.0l (Really) Sprint 1.7 Triumph Speed Triple: Black with extra black bits www.cuore-sportivo.co.uk |

Correct: it turns, but no indication of spark at all.
The frustating part is that it seems to run flawless at some point but then the next morning.....

Could be I guess. Ground strap to the engine may well have that kind of effect. -- Catman MIB#14 SKoGA#6 TEAR#4 BOTAFOF#38 Apostle#21 Tyger, Tyger Burning Bright (Remove rust to reply) Alfa 116 Giulietta 3.0l.

Well, that's not quite it. Once it runs, it runs. It doesn't die while
driving. I'll check both your suggestion and the one made by MeatballTurbo though. Thanks...

Aye. Check the grounding strap, and the battery ground as well come to that >Thanks...
