Hi Robert. You are not alone with compressors that run and run and run, but don't build pressure.

Look at the nav bar, click Compressor Issues, and then compressor troubleshooting. Read all the pages linked from "will not build pressure".

After doing the checks posted, if you still have problems, post here as a comment telling me what you have checked and what you have found, K?

Cheers,

Bill
