As the title says, got her started today after my weird issue with no spark, well she started yesterday then died again :/ . so today i cleaned and replaced the connectors from the ignition module to the coil, and all others related to the coil, also cleaned all the earth's, and took off the battery isolation switch (had to remove that, broke the top off taking out the battery!). turned the key and hey presto, she was alive although it did seem a bit rough. Let her warm up and she was fine :) .

Decided to spend the day driving her so off i went. After ages of off driving, she became hesitant again and felt very rough to drive, was in 4th at the time so dropped it in 3rd, had my foot down and she just wouldn't pick up, stayed at the same speed (don't ask what no speedo at the moment, was around 25/30). at the point the car became hesitant the rev needle also went mad, was staying right at the top near the red line, and at one point just stayed at max revs, i know i wasnt revving that much even though my foot was flat down.

my thoughts were either the coil or the module on the dizzy. if im not mistaken the module is kind off like a switch to ground the coil, controlling the spark. and the revs work from this ground aswell? so when the module sends a ground to the coil, it also sends it to the rev counter?

surely some one must be able to give me advice on this

It can be ether the dizzy module or a bad coil contact. Could also be the coil itself, but coil failures are not as common as ignition modules failing..
And those are a bit pricey so disconnect, re-check and clean all coils connections before replacing the dizzy module.

thanks for that, well i think itll be one of those 2 things failing, wires have all been checked cleaned and connectors changes as needed.

Is it still missfiring now? Or it does intermittently?

[shabir]

its a random thing to be honest, not that often but seems to be getting worse when it does happen, like today was the worst ever. and on two occasions ive had the car just cut off, with no spark, im guessing this is related. Didnt replace anything on either of the two times, first time i did nothing, this time i did allot of investigation, checked all the wiring etc. then she fired up yesterday (didnt expect her to just decided to turn the key), then died again, with no spark, then looked at the wiring again today and she fired up no probelem

Sounds like a wiring problem, like loose conncetions, bad quality wiring or no water shields fitted. Could also be the ignition module on its last legs.
Also did you spray WD40 over the contacts? Thats a very bad idea and if thats the case, clean all the contacts and refit them well tight.
If all else fails, try a different ignition module.

No water shield fitted but that day I drove it after it started was a dry day, was raining and very cold night before tho. No WD40 was sprayed. Just cleaned and made sure all connections are good and strong.
