Inspection

1. 1
   Inspect injector resistance.
2. 2
   Using an ohmmeter,measure the resistance between the terminals.

   Resistance: 13.4 – 14.2 Ω at 20 c (68 f)

   

3. 3
   Inspect injector inspection

1. Purchase a new fuel tube, and take out the fuel tube connector from its tube.

2. Connect sst and fuel tube connector to the fuel pipe.

   Sst 09268–41047 (90467–13001, 95336–08070)

1. 1
   Install an o–ring to the fuel injector.
2. 2
   Connect sst (union and hose) to fuel the injector, and hold the fuel injector to prevent gasoline from splashing out. sst 09268–41047 (90467–13001, 95336–08070, 09268–41110, 09268–41300)

   

3. 3
   Put the fuel injector into a graduated cylinder. Hint

   : install a suitable vinyl tube onto the injector to prevent gasoline from splashing out.

4. 4
   Operate the fuel pump.
5. 5
   Connect sst to the connector of fuel injector.

   Sst 09842–30080

6. 6
   connect sst to the battery for 15 seconds, and measure the injection volume with a graduated cylinder.

   Test the each fuel injector 2 or 3 time.

Injection volume: 60 – 73 cm3 (3.7 – 4.5 Cu in.) Per 15 seconds difference between each injector: 13 cm3 (0.8 Cu in.) Or less

1. 1
   Inspect leakage
2. 2
   in the condition above, disconnect the test probes of the from the battery, and check the fuel leakage from the fuel injector.

   Fuel drop: 1 drop or less per 12 minutes

1. 1
   Inspect fuel pump resistance.
2. 2
   Using an ohmmeter, measure the resistance between the terminals.

   Resistance: 0.2 – 3.0 W at 20 c (68 f)

3. 3
   inspect fuel pump operation
4. 4
   apply battery voltage to both terminals. Check that the pump operates.

• these tests must be done quickly (within 10 seconds) to prevent the coil from burning out.
• Keep fuel pump as far away from the battery as possible.
• Always do the switching at the battery side.
