Coil pack burning up...

Coil pack burning up, same one, takes about 2 mins

Mechanic's Assistant: What year is your MINI?

91 z32

Mechanic's Assistant: Are you fixing your MINI yourself? What have you tried so far?

Some one else is, but checking the wiring harness, wondering if it could be the PTU

Mechanic's Assistant: Have you checked all the fuses? Do you have a wiring diagram?

No sorry I don't

Mechanic's Assistant: Anything else you want the mechanic to know before I connect you?

It runs flawlessly until the coil burns up, it's No. 5

300zx twin turbo

When this issue happens, you will need to replace the Ecm, All 6 coils and replace the Negative battery cable. The Negative battery cable builds up a high resistance to ground and that damages the ignition coil circuit in the Ecm and then the Ecm keeps burning out coils. So I am afraid, all that will need to be replaced to resolve your coil melting issue.

I was in trouble with an electrical issue with my brand new Nissan. I frantically went online trying to find help and luckily I found your site. I reached a NISSAN tech named RIP. He was absolutely tremendous and helped me work through the issue. What a pro!
