ISSUE: EEC IV Quick Test service code "87" (fuel pump circuit failure) stays in continuous memory. This is caused by revisions in the fuel pump circuit of the wiring harness during key off mode.
ACTION: No corrective action is required.

NOTE: A service code "87" in the continuous memory does not always mean trouble. Service code "87" is still valid in the key on/engine off (KOEO) self-test.
