^ Engine cranks but will not start or is hard to start
^ After starting, the MIL (oxygen sensor) light illuminates
Customers complaining of these problems should have the vehicle diagnosed according to the procedures listed in this bulletin.
PROCEDURE - ENGINE WILL NOT START OR HARD TO START
1. Crank engine without depressing the accelerator pedal.
2. If the engine does not start after ten (10) seconds, stop cranking the engine. Wait ten (10) seconds and crank again. Repeat this process until the engine starts.
NOTE:
When the engine starts, keep starter engaged until the engine speed reaches 750 rpm.
Service Advisors should inform customers that short cranking periods will contribute to hard starting. A long cranking period may be necessary during cold temperatures. Recommend that the customer use 5W-30 oil during the winter months.
REPAIR PROCEDURE - A
1. For 626 / MX-6 Vehicles - Install the timer kit according to the instructions in Service Bulletin, Category F, No. 003/94.
2. For MX-3 Vehicles - Install the timer kit according to the instructions under MX-3 Timer Installation in this bulletin.
NOTE:
DO NOT install a timer kit if the MIL is illuminated and oxygen sensor is malfunctioning.
REPAIR PROCEDURE - B
If long cranking is required to start the engine, the oxygen sensor may become soaked with fuel. The procedures below should bum off the excess fuel.
1. If the engine is cold (MIL is off), run engine at 4000 rpm for 10 seconds.
2. If the MIL is On when the engine starts, run engine at 4000 rpm for 5 seconds.
NOTE:
Stop the engine if the coolant temperature gauge exceeds the normal range.
