Ignition problems please help

MAke sure its in park( just move it though the gear shifts) sometimes the neutral switch gets sloppy age/usage/transmission swap etc. Check for voltage at the coil positive terminal when the ignition key is on. YES there is voltage, the problem is on the trigger side of the coil (pickup, crank sensor, ignition module or primary wiring circuit). If there is NO voltage at the coil, the problem is on the supply side (the ignition switch or ignition wiring circuit). Check Relays and Fuses.

The Codes 302 & 303 are cylinder misfire codes,google them

Spark Plugs have nothing to do with misfires,it would be rare in
a life time if one ever failed to fire

Forget the 316 just misfires on start up

A repair shop would be your best choice without knowledge,
reference material & test equip

Ignition coil or vacuum leak problem

I would try a spark plug first (cheapest) about $5 for a platinum plug. I would see if the spark plug is firing before putting it in. Pull the spark plug wire off of existing plug put it on the new plug and ground the plug. Crank over or start the engine, is it firing? If not spark plug wire would be the next cheapest. You may be able to get just one wire, but I would replace the whole set. If it still is not firing the coil pack is probably bad about $60-70. If it is firing in the above steps it could be the injector is not working. You could drive the car as is, but it would drive me nuts, I can't stand something that doesn't run right. You will naturally be low on power and probably not doing your gas mileage any good either.

The following procedure will reset your oil change light. Thank you for using Fixya!

2008-2010 Sable

1. Turn the ignition to run (one position before starting engine).
2. Press and release SETUP to display "OIL LIFE XXX% HOLD RESET = NEW".
3. Press and hold RESET for 2 seconds and release to reset the oil life to 100%.
4. Turn the ignition off and then start the engine to verify the indicator has been reset.

Hello Loren.
There are two different engines on the Sable that year. Both 3.0 liters but one has a dual overhead cam engine.
I'll go with the more common single overhead engine.
Squeeze the tabs to remove the ignition cables from the top of the coil. It would be a good idea to mark which one goes where first.
Then undo the capacitor connector. Undo the four retainer screws.
Reverse to reinstall.
Apply a film of di-electric grease to the coil towers before you put on the coil wires.

If yours is the dual overhead cam, let me know here in comments and i will give you directions.

Thank you for using FixYa.

make sure the injectors are getting power.

should be a coil pack just unbolt it

what engine? 3.0L 2 Valve? 4 Valve?
3.4L SHO engine?

The PCM (engine computer) fires the coils, but it is never the cause of a problem. I suspect it is the crankshaft position sensor on the front of the engine by the crank pulley. easy to change.

Crankshaft Position Sensor The crankshaft position sensor (CKP sensor) (6C315) is a variable reluctance sensor triggered by a 36-minus-1 tooth trigger wheel located on the crankshaft pulley and damper. The signal generated from the crankshaft position sensor is called the crankshaft position (CKP) signal, which provides base timing and crankshaft speed (rpm) information to the ignition control module (ICM) (12K072). Base timing is set at 10±2 degrees before top dead center (BTDC) AND IS NOT ADJUSTABLE. The powertrain control module (PCM) (12A650) will use this information with the spark advance information to determine ignition coil (12029) turn on or turn off time.

I had the same problem with my 97 sable it turned out to be the ecm module.

take ignition modual off of distributor and have autozone check to see if it is bad.
