If your timing is off, then you car will start but run badly.



As to how long: It would take the pro's about 1 to 2 hours to do all that. You can give yourself another 1 or 2 hours if this is your first time.

As to why your car is NOT starting, you are not giving us enough info as to why. Was your car running rough before it died? Did you recently have any work done? Did you see any smoke in the exhaust when it was running. etc.

Get an engine diagnosis test done on your vehicle. As far as the plug wires and ignition coil goes, this is a real simple job to do. All you have to do is get a wiring diagram of how to set the firing pattern of the ignition distributor and start replacing the wires one at a time until done. You can get this information for free at any auto parts store or online.I have a 1986 oldsmobile 98 and how long will it take to change spark plugs and wires and the coil?
My guess is its probably not the spark plugs or the spark plug wires. Because not all of them would go bad at once if a couple of them are bad it would run real rough but it would start.



The possibilities could be a coil or your ignition module. Generally you'll have an intermittent problem before they totally go out, but, its still possible that they can.



First check to see if you're getting spark to the plugs. Take off one spark plug wire and insert a screwdriver into the end. Set it very close to the valve cover or something else that's grounded and have someone turn over the engine. You should see and hear a spark. No spark means either a bad coil or bad computer module. Another possibility is the center wire to the coil could be bad which would cause a really weak spark to all the plugs causing it not to start.
