1.TEMPORARILY INSTALL FUEL (ENGINE ROOM SIDE) PUMP ASSEMBLY
When replacing the fuel pump assembly, it is necessary to replace the No. 1 fuel pipe sub-assembly with a new one.
Perform "Inspection After Repair" after replacing the fuel pump assembly.
| *1 | Fuel Pump Assembly |
| *2 | Fuel Pump Lifter Assembly |
| *3 | No. 2 Camshaft |
| *a | Correct |
| *b | Incorrect |
Turn the crankshaft pulley until the flat of the camshaft faces the fuel pump lifter assembly.
This prevents the camshaft nose from pushing up the fuel pump lifter assembly when installing the fuel pump assembly.
| *1 | Cylinder Head Cover Sub-assembly |
| *2 | Fuel Pump Spacer Gasket |
| *a | Pump Drive Cam (Engine Oil Application Area) |
| *b | Fuel Pump Lifter Assembly (Engine Oil Application Area) |
Apply 30 cc (1.8 cu.in.) of engine oil to the pump drive cam.
Apply engine oil to the fuel pump lifter assembly.
Install a new fuel pump spacer gasket to the cylinder head cover sub-assembly.
| *a | Fuel Pump Lifter Assembly (Engine Oil Application Area) |
| *b | Fuel Pump Lifter Guide (Engine Oil Application Area) |
| *c | Stopper Key |
| *d | Key Groove |
Apply engine oil to the inside of the fuel pump lifter guide and the outside of the fuel pump lifter assembly.
Set the fuel pump lifter assembly on the fuel pump lifter guide as shown in the illustration.
Align the stopper key of the fuel pump lifter assembly with the key groove of the fuel pump lifter guide.
Apply engine oil to a new O-ring and install it to the fuel pump assembly.
Do not damage the O-ring.
| *1 | Fuel Pump Assembly |
| *2 | Fuel Pump Flange |
Set the fuel pump flange and fuel pump assembly on the cylinder head cover sub-assembly as shown in the illustration.
Temporarily install the fuel pump assembly with the 2 bolts, leaving some allowance for left and right movement.

2.TEMPORARILY INSTALL NO. 1 FUEL PIPE SUB-ASSEMBLY
Do not damage the seals of the union nuts of the No. 1 fuel pipe sub-assembly.
Temporarily install the No. 1 fuel pipe sub-assembly to the fuel delivery pipe and tighten the union nut by hand.
Temporarily install the No. 1 fuel pipe sub-assembly to the fuel pump assembly and tighten the union nut by hand.

4.INSTALL NO. 1 FUEL PIPE SUB-ASSEMBLY
| *a | Torque Wrench Fulcrum Length |
Using a 17 mm union nut wrench, tighten the union nut on the fuel delivery pipe side of the No. 1 fuel pipe sub-assembly.
Do not adjust the torque in the loosening direction.
Calculate the torque wrench reading when changing the fulcrum length of the torque wrench.
When using a 17 mm union nut wrench (fulcrum length of 30 mm (1.18 in.)) + torque wrench (fulcrum length of 180 mm (7.09 in.)): 30 N*m (306 kgf*cm, 22 ft.*lbf)
| *a | Torque Wrench Fulcrum Length |
Using a 17 mm union nut wrench, tighten the union nut on the fuel pump assembly side of the No. 1 fuel pipe sub-assembly.
Do not adjust the torque in the loosening direction.
Calculate the torque wrench reading when changing the fulcrum length of the torque wrench.
When using a 17 mm union nut wrench (fulcrum length of 30 mm (1.18 in.)) + torque wrench (fulcrum length of 180 mm (7.09 in.)): 30 N*m (306 kgf*cm, 22 ft.*lbf)
Connect the No. 1 fuel pipe sub-assembly to the cylinder head sub-assembly with the bolt.
Connect the connector to the ignition coil assembly.

6.INSTALL INTAKE MANIFOLD
7.CONNECT CABLE TO NEGATIVE BATTERY TERMINAL
8. INITIALIZATION AFTER RECONNECTING BATTERY TERMINAL
When disconnecting and reconnecting the battery, there is an automatic learning function that completes learning when the respective system is used.
9.INSPECT FOR FUEL LEAK
10.PERFORM INITIALIZATION
Perform "Inspection After Repair" after replacing the fuel pump assembly.
