Ok I’m a newbie so bear with..
I have a MK 2 1.6 1998 model
It started having a mis-fire problem so I took it into a garage; they diagnosed it to be a coil pack problem and ordered one. When it arrived they couldn’t fit it as it was the wrong one and said they would track down the right one and let me know when they got it. In the meantime they asked me to take the car home.
It was now running rougher than before, so when I got home I looked under the bonnet and noticed they had reconnected the leads in the wrong order, once connected correctly I was back where I started. Not happy about the leads though.
I looked on flea bay to see if I could track down the right part, I saw one that was supposed to be for my model and year so bought it.
It arrived and looked on here about how to fit it so thought I’d do it myself and save some money.
The problem was it was not the same as the original.
The original one had a connector on each coil with 3 pins (red / black/green) and (red/black/blue). These two come together to one loom connector with 2 rows of three pins. A six pin connector.
The one I bought only had 3 pins to the loom connector (red/white/black with white)
I stupidly thought that they must be doubled up and spliced in the bought one on the original’s wiring connector.
Using one of the reds to the on the six pin connector to the red on the three pin and then the green to the white and the blue to the black with white, assuming these to be the triggers.
Obviously this didn’t work, the engine cranked over but no spark, so I thought ok I’ll put the original back. Unfortunately that now doesn’t work either, same problem the engine cranks but no spark on any of the leads.
I have checked every fuse inside the cabin and under the bonnet I can find – nothing blown.
What am I missing, what kind of damage may I have done?
I now have got a correct replacement coil pack but have not yet tried it in case I damage it before I know where the problem lies?
Any help gratefully accepted and appreciated.
