Check the following items in the order listed until you find the open circuit. Check the BLK/WHT wire and connectors between the under-dash fuse/relay box and the ignition switch and between the under-dash fuse/relay box and the starter. Check the ignition switch, refer to the '01 Civic Shop Manual on this CD (see page 22-83). Check the transmission range switch and connector (A/T). Check the starter cat-relay (A/T). Check engine speed during cranking. Is engine speed above 100 rpm (min-1)? YES - Go to step 8. NO - Remove and disassemble the starter and check for the following until you find the cause. Excessively worn starter brushes Open circuit in commutator brushes Dirty or damaged helical splines or drive gear Faulty drive gear clutch Check the cranking voltage and current draw. Is cranking voltage no less than 9.0 V and current draw no more than 150 A for D14Z6, D16V1 (KE model), D16V3 engines, 8.0V and 200 A for D16V1 (KG, KR, KS models) engine with A/T, or 8.0 V and 300 A for D16V1 (KG, KR, KS models) engine with M/T? YES - Remove the starter and inspect its drive gear and the flywheel or torque converter ring gear for damage. Replace any damaged parts. NO - Remove and disassemble the starter and check for the following until you find the cause.
