code 68 please help

95 chev c1500 4x4 code 68 pump motor problem what does this mean.....thanks

What sucks about getting a error code it dose'nt narrow the problem down to its source. If you take it to a dealer or even go to Auto zone or Avdance Auto parts they can give you a better explanation of what the code means. I hade the same problem with my 2001 S-10 but differnt code, so I went every where to get it fixed. The problem might be a bad senser or the bad fuel,air,water pumps. I hoped I helped some what.
