Notes On Intermittents

If fuel pump test point is grounded, the fuse will blow and code EO20 will set. If necessary, replace fuse. Start engine and allow it to idle. Manipulate affected wiring and connectors. If fault occurs, the fuse will blow and engine will stall.

Review snapshot data parameters stored with this code to verify failure. If failure is verified, check and repair intermittent wiring connection or sensor.
