Underhood fuse block swap out relay #7 thats the ECM relay.
Ground Circuits Using a DVOM, touch negative voltmeter lead to a good ground. Touch positive voltmeter lead to each ground terminal. With vehicle running, voltmeter should indicate less than one volt. If reading is greater than one volt, check for open, corrosion and loose connection on ground lead. See ECM GROUND LOCATION table for ECM ground location.

ECM Relay 1. Remove relay from connector. Test for continuity between terminals No. 1 and 2. See Fig. 6 . Continuity should exist. Test for continuity between terminals No. 3 and 4. Continuity should not exist. 2. Apply battery voltage between terminals No. 5 and 6. Test for continuity between terminals No. 1 and 2. Continuity should not exist. Test for continuity between terminals No. 3 and 4. Continuity should exist. Replace relay if defective.
