No fire to spark plugs on a 2000 Saturn sc-1 coupe

THE CARS VIN 8TH DIGIT TELL WHAT ENGINE IS THERE, so which one is it.?
check all fuses first, as in all (cab and bay boxes)
and battery must be charged and good first. and kept charged for this service and testing.
no spark on just one cylinder or all ,(no engine told of 2)???????
the service manual covers all that.

so starter does crank the engine fast?and robustly? not slow as slug.
1.9 L, SOHC, SINGLE CAM
1.9l DOHC TWIN CAM ENGINE
2.0l
3.0L ? V6?
THEY ARE not THE SAME AT ALL , FOR EFI OR SPARK
BUT Both engines run a pair of twin coil packs
rule1:
the 2 HV lugs on each pack both must be wired to the correct spark plug !!!

or firing order is noW dead wrong and fails. called wasted spark.

rule2
2nd rules is it those old 24 year old wires sets (junk) if one fails open, that makes 2 spark plugs go dead and bingo it will never start as 2 cylinder engine ever. never ever run 24 year wire sets, of fail you will !!!
go NGK mag-wire sets in fact. best.
rule 3: wasted spark
to test spark never pull 2 HV wires on one coil pack . test HV wires 1 by 1 using clean new test spark plug.
yes 2 can be tested at the same time but lets skip how now, do thme 1 at a time
spark tests. do not skip any.



scan the PCM yet for DTC errors, be big shame to miss out ,omg the PCM sees CMP or CKP dead. cam or crank sensors errors or coil pack errors.

Id have new spark wires installed this old. 24 years.
and now rule #4 wasted spark
do not pull off all wires to it replacing the pack
do so 1 wire off old pack on back on to the same exact lug. on new pack
or , firing order is lost.


for the 1.9L (wild guessing me the engine)
if you get it all messes up the cure is here
4 and 1 fire same time
2 and 3 fire same time, paired.

You still have a problem with your starter. Sounds like you missed the wires going to the solenoid which engages the bendix.
Recheck the wiring.
It could also be a bad starter from the parts store. Won't be the first time.
See if this helps -


Saturn SL SC SW Starter Replacement

If it won't even ''crank'', then it is probably a bad ignition switch. If it does ''crank'', then there are too many possibilities for internet diagnosis. (But if _no crank_ after starter and battery replacement, it's a good bet that it's a bad ignition switch).

Firing order is 1-3-4-2.

Does your engine look like this? I have numbered the wires to their respective plugs. NOTE: this is not the firing order, I used to numbers only to match the wires to the plugs. Hope this helps !

Someone would need to check for power and ground at the coils and that the timing belt is ok.

The cylinders from the passenger side to drivers side are 1-2-3-4 The coils from passenger to drivers side are 4-1-2-3 Match up the coil number to the cylinder number and you should be running in no time.

First make sure all wires are tightand connected correctly.
2nd check for spark at distributer then plugs.
3rdcheck for any reset button for gas .
4th check fuses

If the starter/Battery are ok.Check for spark by pulling off a sparkplug wire,have someone try to start hold wire near sparkplug tip you'll hear the spark jump to the plug tick..tick..tick..sound.Be carefull to hold wire just far enough to hear spark,also this is the secondary circuit from the coil it's high voltage wear a glove.If you smell gas youre geting gas if no spark it is 1 of the following.Bad Coil, or ignition modulator, crack in distributer, cracked wires that cause spark to not reach plugs.Good Luck.

IT COULD BE MANY THINGS BUT i FOUND THAT THE COMPUTER WAS BAD IN MINE AND ALSO THE CRANKSHAFT SENSOR WHICH IN LOCATED BEHIND THE FUEL INJECTORS AND ABOVE THE STARTER.
I WOULD CHANGE THE CRANKSHAFT SENSOR FIRST.
IT COST $15.00
HOPE THIS HELPS..
