Question about 1996 Saturn SC

1 Answer

Okay, i just got done pulling my spark plugs and wires out so i could test my spark. Only two plugs are firing right. And those two plugs are on the same coil pack. The other two are only firing sometimes!!!! Could this be my coil pack? And is that the reason why its smoking and bogging down REALLY BAD?

The spark issue is caused by the coil packs, this will cause the bogging down, the smoke could be from several issues beside the spark, can't tell till you repair the coil packs

Po306 new intake gaskets smoke test compression test leak down test new plugs wires tested injectors swapped injectors checked ijjector wiring with noid still when you pull off no 6 wire it changes nothing...


Code 306 means cylinder 6 is not producing power. And as you know it takes fuel, spark, and compression at the right time to make power.
Generally, if the injector is firing at the right time the spark plug should be firing as well.
Are you sure the plug is firing ? And is it possible injector 6 has no fuel to spray ?

No fire to sparkplugs


Bit late here, but I love Datsuns! First check if you are getting power to coil on the + side of coil. Pretty much a straight path from ignition switch to coil. Then pull off coil to distributor cable at the distributor and check for spark on that wire when cranking engine over. If good, rotor, distributor cap, plug wires, or sparkplugs need checked. If no spark from coil, it should be tested with an ohmmeter for proper resistance values, or swap in another coil.
Does it have mechanical points and condenser or electronic ignition?

Have 1994 toy. truck with v6, when choke goes off the engine misses


Hey 94 TOY...

When did the problem start? Before you changed the wires and plugs? Or did it start, AFTER you changed the wires and plugs? Did the problem remain the same BEFORE & AFTER you made the changes?

1 - If the TOY ran fair to Okay before you did the work, then you may have done something wrong when you made the cahages. Check for correct plugs and firing order. Check for cross wiring. With engine runing pull one plug wire off each plug one at a time. Each pulled plug wire will slow down the engine. When you pull a plug wire that doesn't react and does not make any change ON or OFF that cylinder Plug.
Then that cylinder is not firing.

2 - Check for spark at that wire. If you do-not have Spark there, But the other wires do... the wire going to that cylinder is BAD.

3 - If you have the correct firing order and spark at all cylinders then the cylinder that did-not change the speed of engine has a compresstion problem. Bad valves, Piston or rings are bad... Major engine work and Major repair bill for the repair job.... GOOD LUCK....

1998 Mercury Sable Cylinder 5 Misfire


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.

92 civic engine stalled while driving; fuel pump works; replaced all plugs seeing some oil on old ones. only one plug fires; is coil still working? or the distributor? haven't checked fuel...


Hi,
Check the ignition distributor cap and clean the electric contact points it might be already dirty.

if one has a spark that means your ignition coil is still okay. Remove the whole cap and check the inside part and clean it, use emery board.
Check also the high tension wires( spark plug wires ).
Hope Fixya helps you!

Gfs car was lacking power big time seemed like an electrical or timinmg issue so i yanked off one plug wire from the coil no change in sound,yanked the one behind that same thing(right hand side of coil...


it does sound like you have a plug lead out take one off the spark plug and plug another spark plug in to it place the plug to earth and crank the engine over there should be a spark there
also get a compression test done because if there is a brake in the head gasket between 2 cylinders then it will run rough and possably misfire

Changing spark plugs on lincoln town car


Remove the spark plug wires, remove the spark plugs,replace them. Do this one cylinder at a time if you never did it. On that year you may need to remove the upper intake to access the plugs on one side. In that case go to a shop. This would not be a novice job.

My cavalier won't start


Okay there should be a plug on there make sure it is pluged in all the way. If you have someone to help you pull one of the spark plugs out plug it in to the wire (Do Not Hold Wire with Bear Hands) use insulated pliers.try to start car if you don't see a spark from plug then it means that the coil pack is bad. If it does spark then it is possible thet it may be a fuel problem.
