The other day I was changing the belts on my 85 k5 and I just wanted to take off the compressor for the a/c. I unpulgged the compressor and the k5 would not start, it was just making a cliking noise. I plugged the compressor back in and it would start. I took off the compressor completely to remove the hoses then bolted it back on and plugged it back in and now it wont start at all. Give me some help.
