Make sure the wires leading to the coils you had tested are still good and connected properly. Wire gets weak and brittle over time and the movement caused by removing/replacing the coils could have created an internal break or short someplace.
Also, make sure the kill switch is not turned off

Try a new spark plug. Also, the plug wire may have gone bad or the plug cap may have a bad connection.

Hi, my bmw e30 323i has a start problem, it only starts when its cold but hot it doesn't and when I check the plugs and (replace)coil and the coil plug isn't firing . Can I ask for help what's the problem...

Did you check the ECM or ignition module. You need a computer tester for that but they are not that much today. To me it sounds like an ignition module though

Brain box

The misfire causes unburnt fuel and air to pass by the oxygen sensor. The sensor sees the oxygen and thinks more fuel is needed, so it adds gas. Focus on the misfire, bad spark plug, ignition coil, plug wire. A clogged fuel injector also causes a misfire but less common.

No spark already replaced coil an brain box

Hi, Mike if you have a CKP sensor it needs compression to send the correct signal to the ICM/ECM, make sure both spark plugs are in heads and use a grounded third plug to check for spark or hold spark plug cable close to spark plug in the head. If still not getting spark the usual suspects are:
1. Fouled spark plugs.
2. Discharged battery, check battery terminals for damage or corrosion, check the battery cables at "BOTH" ends for loose, corroded, or broken connectors, "INSIDE" and outside the cable harness, perform connector wiggle test and check cables with an ohmmeter if necessary.
3. Loose connection at ignition coil or plug between ignition sensor and module.
4. Spark plug cables in bad condition, shorting / leaking, spark plug cable connections loose.
5. Faulty ignition coil or ignition / electronic module
6. Failed CKP, CMP, or BAS sensor.
7. Faulty ignition switch.
8. Security alarm failing to disarm needs reset

94 chevy 1500 4.3 no spark no fuel

Sounds like you replaced alot of parts for nothing.
The pickup coil in the distributor "fires" the module which grounds the coil and the injectors.
Those components would need to be tested. The coil fires the plugs when the ground is removed by the module or the key switch.

Got a 85 toyota pickup..will not start..replaced coil, brain box, and all fuses...still no fire from the coil?

Not sue what you mean by brain box. You may need to replace the ICM the Ignition Control Module that sits right below the coil. Mine cost almost $300 locally, but found them online for less then $100. When mine went out in my 1985 Toyota pickup I was doing about 45 MPH and it was just like someone turn the key off., dead, no spark nothing. I ran the troublesooting steps in my repair manual and found it was dead.

How do I change the spark plugs on a BMW 523i engine and what is the correct spark gap?

The spark plug change is very straight forward. Basically, you remove the plastic valve cover trim panel, unplug the harness plugs from each of the ignition coils, remove the two nuts securing each coil, pull the coil up. The rubber spark plug connector boot should come up with the coil. You can now remove the spark plugs.

The spark plugs are not gappable. Install them as they come out of the box.

Replace the rubber connector boots at the same time, these wear out and can cause miss-fire problems.

Note that if you find oil in the spark plug wells, the valve cover gaskets must be replaced. Not only does this make a mess, but it deteriorates the boots and also causes miss-fires.

See the DIY article in the Spring 2005 issue of the Bavarian Autosport - Fast Times newsletter (see link below):

Contact Bavarian Autosport for the spark plugs and connector boots (and valve cover gaskets) at 800-535-2002, or order online.

I can't find the spark plugs for 1995 BMW 325i.

The 2003 BMW 325i uses a coil-over-plug system, so the spark plugs are connected directly to the coils, deep in the cylinder head.

To get to the spark plugs:
  1. Remove sound reduction or ignition coil covers as needed
  2. Open control box cover
  3. Disconnect ignition coil electrical connector by lifting up plug lock
  4. Remove ignition coil by pulling straight up
  5. Use the necessary tools to remove the spark plugs
There are six plugs, and the factory plugs that come with the car are most likely the NGK BKR6EQUP (laser platinum, 4-ground electrode) ... or if it's not the platinum version, the BKR6EKUB (a dual-ground electrode, semi-surface discharge type).
