Caution
l Be carefui of following points after turbocharger removal.
l Do not carry the turbocharger by the actuator rod or actuator hose.
l Do not drop the turbocharger.
l Set the turbocharger down with the turbine shaft horizontal.
9 Cover the intake, exhaust, and oil passages to prevent dirt or other materia1 from entering.
l Use the specified new studs when installing the turbocharger.
1. Disconnect the negative battery cable.
2. Lift up the vehicle.

3. If not within specification, perform the following inspection,
and repair or replace if necessary.

l ECU II terminal voltage. (Refer to page F2-60.)
l Wiring harness and connector.
inspection
1.. Disconnect the connector.
2. Ground the fuel pump resister relay terminal D.
3. Apply 12V to terminal C and check for continuity between
terminals A and B.

INJECTOR
Volume Test
1. Remove the injectors with the delivery pipe.
2. Affix the injectors to the delivery pipe with wire.
Caution
l Affix the injectors firmly to the delivery pipe so that
no movement of the-injectors is possible.
Warning
l Be extremely careful when working with fuel.
Always work away from sparks or open flames.
3. Connect the SST to the battery and injector.
4. Check the injection volume with a graduated container.
Injection volume:
BP SUHC....44-47 cc (2.68-2.87 cu in)/15 sec.
BP Turbo
. ...87-105 cc (5.31 -6.41 cu in)/15 sec.
Caution
l When using the SST, make sure of the SST num-
ber and use correct one.
5. If nut correct, replace the injector(s).
