Most likely the ignition coil or DIS System is not shorted out, but disabled. This vehicle is equipped with a passkey security system. What this system does is disable the spark to the engine if the computer thinks that the car is being tampered with. The problem can usually be traced to the ignition switch. This is where the passkey sensor is located. Usually replacing this sensor or full ignition switch will take care of the problem. On some occasions though they are few and far between a replacement key cut at the dealership may allow the system to operate correctly. Do keep in mind, this particular scenario only happens about 1 in every 25 situations. I really hope this information helps you. If not please notify me of the problem, I would appreciate the feedback. Good Luck!

Possible ignition switch on steering column. Possible short in ignition coil. Do you have a schematic diagram for 95 Buick? Do you have an ohm meter? I need more information. I am assuming it will not start up or is the car miss firing?? Any check engine light indications?

The computer says the immobilizer coil is open/short

Did you reset the computer. Usually disconnecting the battery for about 10 minutes should do it. If this does not fix it, you need to recheck your work. Something you did has caused the message. Did you short circut a wire, burn a fuse, forget to reconnect something? The immobilizer probably works by immobilization of the vehicle's coil circut. Thus, causing the computer message to display about the coil issue. Try reset computer of vehicle should work.

Code 1320 how to repair

code P1320 ignation signal circuit

it is a long test for this circuit and you will need a DVOM and a Scanner to run the test.

but basicly there are only 4 things that can set the code the ignation coils, the PCM, or the condensor, or the wiring betwine any of these componets, i recomend you take this one to a good shop, with out the test equipment it is only a guess as to what to replace, the most commmon thing would be the coils but it would be just a guess as to which one, it is not a sign of weakness to know when its time to get so help.
