I can point you in the right direction for the #3 plug. You'll find several ways in other posts. My preference is to move the intermediate steering shaft aside.
Briefy as follows-
wheels straight, steering lock off. Unsnap the black plastic cover where the shaft connects to the steering box, remove the bolt (11mm), telescope the steering shaft in and angle it out of the way.
Other ways I've read include 1- accessing through the fender wheel with proper combination of wrenches, 2-or using a suitably angled box wrench directly on the plug base to loosen, then use your fingers.
I am curious to see what you find with the starting issues as my 95 is developing starting issues now. I haven't gone through all the commons items yet.
