You may have blown fuses or fusible links. Is the battery charged up now? Make sure of that before proceeding. Do the headlights work? If no, check Fusible link B, located at the starter solenoid-where it picks up power from the positive battery cable at the starter solenoid.

Does the key switch turn on? Do the warning lights and gauges turn on with the key in on position? If no, check Fusible link A at the starter solenoid. Link A supplies power to the ignition switch.

If a fusible link has blown it can be cut out and replaced. It may look burned-it may have bulges in the wire-it protects circuits just like a fuse, but has somewhat different characteristics than a fuse.

Post back wtih what you have so far. Maybe I can help you more?

Why would you be working on or replacing
something like that on a 27 year old vehicle

Who is going to do that type work & why.

Your just using hand tools & unbolting things that
have to come out or be removed

No step by step instructions for that

I will assume your up to your ears in rust damage, to
the body or axle components & are taking on a restoration
project.

64510fee-4cba-434c-8e76-78dd3cbb1b83.jpgNot sure of your engien size as you didn't say so I went with the most common enegine the 3.8 liter. Again I wasn't sure of what vacuum diagram you needed as the is vacuum for emissions, air conditioning and cruise control. the picture above is for emissions for the 3.8 liter engine. Hope this was what you were needing but if you have a different engine (305 or the 3.8 turbo) you can reply back here with what diagram you needed or the correct engine. Hope this helps...

Have you checked the coil pack and the module to see if they are getting voltage and a ground signal ?

I am assuming you have the 200 4R, I just replaced my tranny fluid on my 87 GN, took about 6.4 quarts. I also have an external tranny cooler and let the tranny drain for about a week.

I would start with 4 quarts and start her up, dont drive anywhere. Keep adding and checking while the car warms up. Every now and then get in and shift through the gears, pausing in each one a few times, ALL GEARS. When the fluid level refisters on the dipstick, take the car around the block slowly at first then fast enough to shift into 2nd, depending on factors 3rd or 4th. Head home and leave engine running, check fluid again and adjust accordingly.

you don`t say where they keep breaking.if its around the bolts then you can use a thicker washer this might help.if the tracking system that the seat slides on then if there is room you might be able to weld a re-enforcing plate to the system where it cracks to stop it.

Is the transmission a manual or at auto? I would assume it is an automatic. This may just be an issue with the fluid levels or the fluid is dirty and needs replacement. It could also be caused by a dirty transmission valve. If the debris is on the first gear valve then you may not be able to run it. If it is on the 2nd valve, then you may only get the first gear. Check for vacuum leaks on the exhaust for the turbo. It would be best to have the boost gauge used on this. Check your wiring, they may be loose or bad wiring due to heat or vibration.

The large vaccum line just behind the EGR valve has popped off. Your HVAC controls works off of the vaccum block.

1) To remove the bottom steering column cover. Use the appropriate sized male torx bit on the middle back screw and also remove the 2 other screws on each side. The cover has plastic loops where it attaches to the dash so you must move it towards the dash and then down to release it.
2)
to remove the top steering column cover. First you'll need to remove the tilt steering lever though. Using a flashlight, look into where the lever attaches to the steering column. You will see a metal tab that you can push on to release the tilt lever and pull it out. Now you can take off the top steering column cover.
3) Looking up from underneath you will see 2 male torx screws holding it on. One on each side of the steering wheel. You can use either needle nose pliers to remove these if you don't have female torx screw bits. Once these are removed, use a pair of tin snips to cut the plastic just below the key lock or you won't be able to get the cover up and around the key lock. Now carefully spread that part of the cover up and around the key lock while pushing back towards the dash with the cover. It should release and come off. Thanks. Keep updated for any more query.

There is a cable and motor that actuates the antenna, the cables break on these all the time.

you can get replacement cables at nos4gn.com

the passenger fender needs to be removed to access the antenna assembly.
