No 4 cylinder no spark.
Hi Guys.
F4i 2003. 55,000 miles.
No 4 cylinder isn’t sparking. I’ve changed over the plugs and coils from a good cylinder and still no spark. I can attach a coil and plug originally from cylinder 3 on to number 4 and it doesn’t spark. Take the original coil and plug from number 4 and it sparks on number 3.
Compression test is all good and fuel is getting to cylinder 4.
Any further ideas?
Regards.
