I wanted to let all who helped me with advice to know my 1993 is running again. Hopefully for awhile. Ha Ha. I found a bad connector that sent pwr to ccrm. Then after not getting a 5vref from pcm I got a used one from ShoSource. I highly recommend them. After replacing pcm the fan would not engage so I got a ccrm from ShoSource. So far everything is working. I probably will forget someone but a special thanks to Rubydist, SHOrod, BAYSHO and SV&HOdan for advice and parts. A special thanks to whoever provides this site to help us non mechanics. Plumber Steve
