SOURCE: Ignition Coil

I own the same car. I would need more info on what happened to be begin with why you think it is the ignition coil.
Your car has an "ignition" ecm (engine control module), on top of that sits your "coil pack" which holds your spark plug wires. If you changed them and crossed your wiring that could be your problem. Let me know I may be able to help you. I just changed both parts on my car a month ago.

SOURCE: coil pack not firing

Hello, this could be your ignition module. This also could be a faulty ECU, crank sensor, ECS computer or TPS sensor. AutoZone can run a free diagnostic on your car to pinpoint your problem for you and I hope this fixes your problem!

SOURCE: 89 oldsmobile 98 won't start

If you suspect its a fuel problem best to do a fuel pressure test, you can rent a tester at auto zone and do it yourself. They also can show you how to use it and what pressure it should be. Also if you turn the key to on position you should hear a hum from the gas tank and then a click that is the pump running and the click is the relay, if you don't then the pump isent running, also chk. the fuse and relay, it could be as simple as a blowen fuse or a bad relay.

SOURCE: 03 Oldsmobile alero vibration will running

I just had my fuel pump replaced on my 2003 Oldsmobile Alero 2.2 4 door sedan and I've been having problems with my car starting. When it finally turns over and starts it drives fine. Now it's been shutting off in the middle of driving. When it does this it starts right back up. Diagnostics reported: Bank 1 Sensor 1 02 Sensor Fault and Air valve high idle fault. Any suggestions?

My 1991 oldsmobile 98 regency elite will turn over but its not getting spark and ive changed the plugs and wires the ignition coils,the cam and crank sensor but still no spark what else could it be?

Could be the security system locking out the injectors. Is the security light on? If you have an extra key try using the other one. Sometimes the pellets wear out.

My 1991 oldsmobile eighty eight royale keeps dying when i drive it, I have replaced ing control moduel, fuel pump, mass air flow , cam shaft sensor, timing chain, plugs wires ect. do i need to keep...

With that much already invested, why give up now? How about the crank position sensor-was that replaced as well? For spark control and spark timing, the computer needs inputs from both the cam position sensor and the crank position sensor before it can know when to cut power to the coils for spark to occur.
Before proceeding any further, you should check for diagnostic trouble codes. You would need an OBD 1 type code reader or scanner for your olds. Any stored codes may help you find the problem.
You can test the ignition system by checking for spark on a spark plug wire when the engine is cranking over. Pull the plug wire off a spark plug and put in a clean spark plug into the wire. Lay the plug so the threads are touching metal on the engine somewhere. Have someone crank the engine over and watch for a spark from the spark plug. If you have a blue, snapping spark when cranking, ignition is good.
One last note: since it dies when driving, there is a possibility that you have a malfunction in the pcm-the computer.

Why is my nissan bluebird arx 1991 jerking while driving

Have you ever done a really through tune up? This would be replacing the plugs, the distributor cap and rotor and the spark plug wires. you may have a misfire in the engine ignition system, misfiring plugs and wires tend to show up more after the engine gets hot.and resistance drops in the secondary ignition systems components.

It will noot start.i replaced the coil and it just

You still need to check the spark plugs. In the ignition system the coil is the least likely problem. I would rank the likelyhood of problems: 1. Spark Plugs, 2. Wires, 3. Distributor cap (if you have one), 4. Coil, 5. Low ignition voltage. Good luck, be sure to cover all bases before giving up.

Jerking and losing power

Probably bad ignition system which can be anything from a failing coil pack,ignition wires or cracked spark plugs. Look closely for signs of missing by looking for cracks in plugs,bad plug wires or a white/green crusty chalk build up on the coil

No spark at plugs on my 1991 volvo 240

Did you replace the plugs? How hot is the spark from the coil thin and blue? if it is big and orange it is a weak coil and should be replaced. If it is good try an other wire from a different car (do not put a spark plug in it) and see what the spark looks like if good put the plug in it and check the spark again if this is a good the wires are bad

I have just had a maf sensor and throttle body put on my suzuki vitara 1997 2ltr petrol v6 engine as I had trouble with it jerking while driving.It still wont run properly it has no power to go up...

No power when going up hill could be a plugged catalytic converter or fuel filter. A bad ignition control module will act up when the engine gets hot and not energize the coils so they can provide spark to the spark plugs. There could also be a bad coil. The ticking could be a bad coil or spark plug wire that is shorting and arcing. If you take a spray bottle with some water and lightly mist the coils and spark plug wires with the engine running in the dark (outside at night) you will see the arcing. Autozone will test your ignition control module and coils for free.

Regards,

Tom
