I'm getting no spark to my plugs and someone mentioned, immobilizer,. Does my 1985 SEC have one and if so how do I turn it off. I'm really desperate here. I know I can fix the problem if I could just find it !

I am fairly certain that the SEC did not have a standard immobilizer. however in that era retro fit was quite common and the format was linked with remote locking fobs and splined key to turn off alarm immobilizer.
To turn off, the splined key was either inserted into an alarm horn under the bonnet (normally covered with a black grommet or sometines located on lower dash drivers side- again hidden under plastic cover.
Good luck and I hope you have the key
