You have relays on both inner fenders...both sides under the hood. The drivers side is your high speed fan relay, low speed fan relay, and then the delay box, which keeps the fan running after shutdown. The other side has the fuel pump relay, the knock sensor module, and something else...cant recall....
Anyway, pop the connectors off and unbolt the relays from the inner fenders. You'll probably have alot of dried out hardened dielectric grease from 20 years ago. Get a pick and pick it all out, then pour some ronsonol lighter fluid or kerosene in all those sockets, and gradually clean it all out. Id recommend a blow gun, but dont use acetone. Pick all that crap out, and also the stuff on the pins on the relays. Take your time and clean it really well because the end result is worth it. You want shiny clean sockets and pins. Otherwise it'll take alot of current to drive the fuel pump and fan and things will get overloaded, and you'll have major voltage drops...like 9-10 volts at the fuel pump and even less at the fan..I had 8 volts going to the fan when I got my car. The fan was hardly spinning. Try this first, and get a scanmaster YESTERDAY. Dont even think about owning a turbo regal without one. Then you can fire it up, let it reach operating temp, go into closed loop, and then you can post all the numbers it's showing and we can help you much better that way.
