1. Fuel pump
(a) Check fuel pump resistance, 0.2~3.0
at 20°. Replace fuel pump if the resistance is not as specified.
See (Figure 93)
(b) Fuel pump running:
Check fuel pump by connecting with battery. Replace fuel pump or wire if the running is not as specified.
See (Figure 94).
The test should be conducted within 10s to prevent coil from damage.
2. Fuel injector assembly
Injection Volume: 40~50cm
3
/s
Error between each injector: less than 10 cm
