1992 GMC Sonoma ProblemsABS Light Due to Brake System Control Unit Failure

Commonly this is caused by a leaking fuel pressure regulator or fuel line. The fuel system will need to be pressurized with the upper intake manifold removed in order to determine the exact cause of the leak. Removing the "tuning valve" from the upper intake can allow for limited visual inspection without removing the upper intake manifold.
An engine oil leak may develop from the distributor shaft o-ring seal.
