Engine Temperature Below 59°F (15°C)

Turn ignition switch "ON" and check the cold start injectors for any leakage. Crank the engine for a few revolutions. Injectors should spray while engine cranks. Do not operate the starter any longer than necessary to complete this test.
If injectors do not spray, crank engine and check for battery voltage at cold start injector supply (White/Pink) cable. If voltage is present, check ground connections and wiring harness connectors at cold start injectors. Repair as necessary. If no defects are found, injectors are faulty and must be replaced.
Crank engine and check for battery voltage at terminal 87 of cold start relay. If voltage is present, check wiring harness between relay and cold start injectors and repair as necessary.
Crank engine and check for battery voltage at terminal 30 of cold start relay. If no voltage is present, check supply wire from pump relay and repair as necessary. If voltage is present, relay is not being energized or contacts are faulty.
Crank engine and check for battery voltage at terminal 86 of cold start relay. If voltage is present, relay is not being energized or contacts are faulty. If no voltage is present, supply wire from starter circuit is faulty and must be repaired.
Crank engine and check for battery voltage at terminal 85 of cold start relay. If voltage is present and relay is not energizing, there is a problem with thermotime switch circuit. Disconnect wiring harness from terminal 85 and jump terminal 85 to ground. Relay should now energize. If not, relay is faulty and must be replaced.
If relay energizes, check for battery voltage at terminal 87 of cold start relay. If no voltage is present at terminal 87, the contacts of relay are faulty and the relay must be replaced.
Reinstall cold start injectors and all cables or connectors that were removed.
