The 1990 engine computer is unique to 1990 Imperials and 5th Avenues with the 3.3L engine. I don't know if this goes for other computers in the car. You should call your dealer and they will tell you the numbers of which computers and from which cars will work for you. You can get a computer at a salvage yard for under $100. Be sure the computer you get is from a car that has similar equipment as your car. Please quote this message in your reply. Otherwise I will be unable to reply to your message.

It was either the owners manual or one of the Haynes books (Chrysler Full-Size 88-93 [FWD]?) if not online. I wish I could remember but as I had no troubles with those I didn't pay much attention to it. In the mean time, one quick thing you might try is to disconnect the car battery and let the car sit for a bit and then see what the reading shows. > one for sale or any idea wher I can locate a used one?

If you haven't figured this bit out and still need to do it, drop me another line over the weekend and I'll try to dig out the take apart diagram.
