The coil pack has been changed and tested and the spark plugs and wires have also been replaced as well. The car is getting spark and fuel but will not start. We've checked all the fuses in the main fuse panel in the glove compartment and they are all OK, except one at the very bottom on the left hand side that's for IGN or Fuel Inj. or something like that. Underneath the passenger dash is the convenience center for the fuses. My roommate removed what looks like a fuse box with eight prongs on one end. Four on the top and four on the bottom. And it plugs in like a big fuse. Three of the plugs broke off, would this have anything to do with the car not starting and if so WHAT is it? We've called around to replace it and even took it to Auto Zone and they couldn't identify it. Could you PLEASE! help us on this. We've been working on this car over a month now and still no starting and we're going nuts!!!! LOL Thank you! Charity Maguire

Re: CAR WON'T START
You might have to take the part you pulled out to a dealer to get a new one, sounds like a relay, might be part of your problem, also the fuse that is blown must be replace, it makes the fuel injectors work
I HAVE A92 LUMINA THAT HAS 70K MILES IT WOULD NOT STARTI WORKED ON IT OVER A YEAR,AND I FOUND THAT AFTER I TOOK OFFWHAT I WOULD HAVE CALLED THE INTAKE MANIFOLD (PLENTHEM)I FOUND THE F.I. WIRES WERE MELTED TOGETHERVERY LITTLE BUT IT WAS ENOUGH TO KEEP IT FROM STARTING

If your car has one wire coming out of the distributor at the bottom going to the coil, you can use a test light between thet wire and ground to see if your coil is getting a pulse. If it has a coil pack, then you might need to clean the connector on the coil pack. follow the coil wires from the plug back to find the coil pack. If your car has points in the distributor, you can connect the test whole circuit by hooking the test light across the points. if it's a coil pack, you might replace the crankshaft position sensor to see that does it. also, use the test light to check power to all fuses.
remove the spark plug wite off the plugs 1 at a time replacing right after testing each so as not to cross wire after one is off test it to see if its getting fire through the wire there is a light bulb like item that can be bought for testing wires at your local parts store if its not getting fire check your coil packs using the same tester and the wire adapter if those arent working there is a pick-up coil that the coil packs are mounted to its a small metal plate least on my car anyways most of the time those go bad and people thing the worst they are easy to change and fairly priced mine costed $38.00 at advanced auto
The spark and fuel system needs to be inspected.---------
The spark plugs are getting fouled or very loose, can cause sputtering problem.Inspect the spark plugs and coil packs.The spark plugs gets power from coil pack.If the spark plugs are very old and dirty, then it needs to be replaced.---------------
The **** problem also relates to faulty worn out spark plugs or clogged fuel filter or low fuel pressure or problem with ignition coil pack.-----------
When coil pack stops giving power to spark plug the car will **** while driving.----------
So very first thing you get tested is spark plugs and ignition coil packs.If they are tested good, but looks very dirty/ worn out, that can also be the reason.----------- But if spark plugs and ignition coil tested ok and cleaned properly, but still same problem, then get fuel pressure tested.If fuel pressure is low, the fuel pump and fuel filter are the cause of problem.-----------
Also one more thing, " IS there check engine light coming ON dash" ? If yes, then get the car scanned at autozone service center.Its absolutely free to get car scanned at autozone.They do it for no charge.-------
In scanning you will get error codes, as per error codes, it will point towards faulty part, causing this sputtering and jerking problem.-----------------
But if there is no check engine light ion dash, then get the above mentioned possibilities checked.That will help.Thanks.Helpmech.
Try switching the ignition coil with the other coil and plug it in and check for spark again. If it works in the other coil location, then you need an ignition coil. Your engine is bad for valve cover gasket leaks which deteriorate the spark plug wires, so if you are going to put in plugs and wires with the new coil, I would recommend replacing the valve cover gasket and spark plug tube seals(included with the valve cover gasket set).
This has a coil pack and four spark plug wires, correct?
If so and you have replaced the spark plug wires and you don't have any spark out number four but you have spark on number one than you have a bad coil. You can remove the number four wire from the coil start the engine. Use. Test light connected to ground and place it near the opening in the coil that the spark plug wire goes into. You should see a sharp strong snappy spark. You may find that you have to hold the test light really close to the metal part inside the oil tower to see any spark.
If this is the case you have a bad coil.
Be careful when checking for spark. There is between 30 - 40 thousand volts generated but the merge is extremely low. If you get zapped it's going to tickle. Bit but it won't kill you.
Good luck and let me know what you find.
There can be disconnected wires somewhere that's why the car won't start. I strongly suggest that you check all the wires specially the one's going to the distributor. Or the coil pack has reached it's break point that's why the car won't start. If the coil pack is faulty, there will be no current to the plugs. You will need to have it replaced to resolve the issue.
Hope this helps and thank you for using FixYa! Have a good one!
it sounds like either your not getting spark, or fuel at the engine. it could be the coil packs/plug wires or the fuel pump/filter its hard to say what to do first. when you get in the car and turn the ignition on to the position just before turning the engine over you should be able to hear the fuel pump kick on in an attempt the prime the fuel system. if you can smell fuel at the engine after cranking for a few seconds its probably getting fuel. if you have access to an ohm meter with a wire clamp you can test each of your plug wires as you crank it to see if your getting spark. each coil pack sends spark through two plug wires. if you cant read a signal from two of the plug wires trace them back to the coil packs and if they go to the same coil pack that coil pack has gone bad. if they go to separate coil packs you may have two coil packs malfunctioning. this is where i would start i hope it helps.

The Code(s) should be telling the specific cylinder(s) that are misfiring. Do you know waht the code is?
Target those cylinders 1st before testing the unaffected cylinders.
The following should isolate the problem(s).
1. Spark plugs - take out-reconnect back to wires and test spark plugs for getting sparks. If none: Don't replace them yet. GO TO 2. If the spark plugs are worn, dirty them replace them.
2. Remove spark plugs form end of ignition wires and test for spark from the wire. If none: Don't replace them yet. GO TO 3.
3. Remove the wires from the coil connection and test the coil for spark for each cylinder. If none: Don't replace it yet.
4. Test each spark plug and wires this way.
5. Coil Packs normally provide fire for 2-cylinders at the same time. The two are paired across from one another.
6. Test the coil for fire, amount of fire and if there is both cyclinders firing.
Misfire and the O2 Sensor got replaced??
Good Luck and get back with me if you need additional help or if this solved the problem.
make sure the electrical plug is clipped on securely.you may have damaged the coil-pack that you are calling plugs.remove it again and place one of the old plugs in it and see if you get a spark when someone cranks the engine for you.If not replace the coil pack.
1. Get an INSULATED wire and hook it to a ground on the car. 2. Get some one to help you 3. pull a spark plug wire off the coil 4. hold grounded wire close to, but not touching, the part where the spark plug wire connects 5. keep hands away from coil and have your helper turn the engine over ( start car and turn off) 6. if there was a spark between the wire and the coil pack it is good. if not, the coil pack needs replaced 7. replace the spark plug wire 8. test the rest
