Cold Start Injector
- Disconnect cold start injector connector. Using ohmmeter, measure resistance between cold start injector terminals. Replace cold start injector if resistance is not 3-5 ohms.
CAUTION:
Fuel line may contain residual pressure. Use caution when disconnecting fuel line.
- Check cold start injector flow and leakage. Remove cold start injector. If bench testing cold start injector, place container under fuel line and disconnect fuel line from cold start injector.
- Connect fuel hose to Special Union (SST 09268-87702-000). See Fig 1
. Attach special union to cold start injector.
- For on-vehicle test procedure, install Sub-Harness (SST 09991-87702-000) to 6-pin check connector. See Figure
for connector location. Install jumper wire between terminals "F" and ground to operate fuel pump. See Figure
.
- Install Special Connector (SST 09842-30050-000) on cold start injector. See Fig 1
. Insert injector into a container.
- For on-vehicle test procedures, reconnect negative battery cable. Turn ignition on. For all test procedures, connect positive (+) terminal of special connector to positive terminal of battery. Connect negative (-) terminal of connector to negative terminal of battery. Fuel should be injected in spray form.
CAUTION:
Perform cold start injector performance test in shortest possible time. Place battery as far away as possible. DO NOT
allow sparks to occur.
- Disconnect negative cable of special connector from battery. Check injector for fuel leakage. Leakage should be less than one drop per minute.
- Replace cold start injector if fuel injection is not in spray form or leakage exceeds allowable limit. Turn ignition off. Disconnect all test equipment.
