FUEL INJECTOR BALANCE TEST CHART
| Cylinder | 1 | 2 | 3 | 4 |
|---|---|---|---|---|
| First Reading | 296 kPa (43 psi) | 296 kPa (43 psi) | 296 kPa (43 psi) | 296 kPa (43 psi) |
| Second Reading | 131 kPa (19 psi) | 117 kPa (17 psi) | 124 kPa (18 psi) | 145 kPa (21 psi) |
| Amount Of Drop | 165 kPa (24 psi) | 179 kPa (26 psi) | 172 kPa (25 psi) | 151 kPa (22 psi) |
| Average Range: 156 - 176 kPa (22.5 - 25.5 psi) |
Injector OK | Faulty Injector - Too Much Pressure Drop | Injector OK | Faulty Injector - Too Little Pressure Drop |
WARNING:
- The fuel system is under pressure. To avoid fuel spillage and the risk of personal injury or fire, it is necessary to relieve the fuel system pressure before disconnecting the fuel lines.
- Do not pinch or restrict nylon fuel lines. Damage to the lines could cause a fuel leak, resulting in possible fire or personal injury.
NOTE:
In order to prevent flooding of the engine, do not perform the Injector Balance Test more than once (including any retest on faulty fuel injectors) without running the engine.
