Looking for Help

[ctgreg]

Hey all,

I had my 1990 out yesterday for a drive and all of a sudden the SES came on. I drove home and ran through a few things. One thing I noticed is that the vacuum pump is running non-stop when ignition is in the "on" position, but it appears that it's not running when car is running. I pulled a Code 16, but for some reason I can't seem to correlate one issue w/ the other. I tried clearing code, but no go.

I also checked all vacuum connections and I can hear one connection in under left front of plenum where two line are attached.

Any and all advice would be greatly appreciated.

Thanks in advance,
Greg
