Fuel Supply System — Injector Resistor / Pressure Regulator: Testing
6-76prose procedureInjector Resistor
Testing
- 1Disconnect the resistor connector.
- 2Check for resistance between each of the resistor terminals (E, D, C and B) and the Power terminal (A). Resistance should be: 5—7 Ω
| Specification | Value |
|---|---|
| Resistance (each terminal E, D, C, B to Power terminal A) | 5—7Ω |

WARNING
Do not smoke during the test. Keep open flames away from your work area.
- 1Attach a pressure gauge to the service port of the fuel filter (page 6-71). Pressure should be: 240—279 kPa (2.45—2.85 kg/cm², 35—41 psi) (with the regulator vacuum hose disconnected).
- 2Check that the fuel pressure rises when the vacuum hose from the regulator is disconnected.
