Hello! I've been there too. I guess you have touched your coil after the engine stops. If the coil is hot, usually the cause is a very high resistance in the high tension circuit. That is between the coil and spark plugs. Probably something makes a false contact or loose conection or the gap at the plugs it too big.
If your coil is cold, perhaps your coolant temperature sensor is bad. This sensor tells the ecu or the cold start valve to squirt more fuel. When it fails your engine can't start when cold or it dies when hot depending on the failure type. Another thing which can go wrong if your coil is cold can be the cold start valve. This is an auxiliar injector located at the throttle body. When it fails, it simply doesn't inject fuel or injects all the time! (Only 80's cars have cold start valve)

SOURCE: No spark?

Hi, common thing with the mazda was the coil or the ignition amplifier going faulty, both of which are located within the distributor, the coil ususally gives the symptoms you describe, a weak spark. The coil is the most common failure aswell for your vehicle i would recommend a new one, also make sure distributor is spinning as it could just be a case of a broken timing belt.

Good luck Davelee

SOURCE: engine turns over but no spark at the plugs.

You can change pick-up coil, you need to remove distributor (mark where rotor is pointing first) Then you need to remove pin in cam gear on end of shaft to remove gear so you can remove shaft from housing. Then you can replace pick-up coil. Install in reverse. Note when removing distributor rotor will move to the right as you lift distributor out, move rotor to right of mark you made when installing distributor back in.

How to change ignition control modular


there are three types you need to know what one it is, one type is on the dispack and the other 2 fit to the distributor one type has 3 connectors and other type has 1 connector, dispack best just to change the whole unit as the pins can brake if you remove the modular of it.

How to R & R of Main Ignition Modual, 1992 Honda Accord


The ignition module is located inside the distributor and costs almost the same as a complete rebuilt distributor. It's usually best to replace the entire distributor on your Accord, to resolve a bad ignition module.

Getting spark and fuel and did a tune up and put new injectors in there but the car cranks but wont start and it is 1988 corvette


The ignition module and the pick-up coil/stator located inside of the distributor is what generates the signal that the ECM (Engine Control Module) uses to time and fire the fuel injectors, as well as the signal to run the fuel pump and the dwell signal timing to fire the ignition coil, and a faulty ignition module can cause any one of these systems to malfunction.

That does sound like a malfunction with the ignition module inside of the distributor, and you can remove the ignition module and have it tested for free at most auto part stores.

If you do purchase a new ignition module be sure that it does come with a silicone grease or a die-electric compound because it is a heat sink and the ignition module will burn up without it.

To install the new ignition module first clean out the mounting surface inside of the distributor. Then completely coat the metal contact surface under the ignition module with a thick coat the silicone grease or die-electric compound and do not leave any of the metal contact surface of the ignition module un-coated with the silicone grease or die-electric compound, and be very careful not to over-tighten the ignition module or it will be damaged.

The same principal applies to HEI (High Energy Ignition) ignition systems with the ignition coil mounted in the top of the distributor cap.

Symptoms of a bad pick up module on a 1996 GMC K2500 Suburban


What I see the most often is a stalled engine with a loss of spark when driving. Once the engine cools off it will sometimes start and run fine for a short while then do the same thing again. Often, but not always, the pickup up coil or ignition module [both are under the distributor cap] have to heat up quite a bit before they will act up. I replace about 10 ignition modules for every one pickup coil but either one can cause the same identical stalling problem. I keep a few known good modules around as test units so I can just replace a suspected bad module and road test it to see if it works. Another thing that can go wrong in these distributors are the magnets built into the pole piece. A weak or cracked magnet can cause all kinds of odd problems such as stalling when placed in reverse, misfires over 1,000 rpm, etc. Worn bushings in the distributor can also cause problems. As far as a specific test you can do to see which part is failing? I wish there was a relaible one. I've tried using a lab scope and module testers to diganose the culprit but you have to catch the problem as it's happening for those tests to be accurate.

1991 Honda Accord -- was driving it when engine suddenly stopped running -- there is power to the coil but no spark -- replaced distributor cap with new one -- still no spark


Tried replacing the ignition module with two different ones from a salvage yard. (Most of the distributors in the salvage yard were either missing completely or the ignition module had been removed - must be a very common problem.) Neither one worked.

Purchased a used complete distributor assembly w/warrantee and replaced the one that did not work. Car started immediately.

Suggestion: If one cannot wait for delivery of a new distributor as I could not, (I located one on line for $126.00 w/warrantee) purchase one from a salvage yard w/warrantee, then get a new one if you are going to be concerned about the longevity of the replacement distributor.

It will not start


as silly as it sounds, pull off the distributor cap and make sure the distributor is turning-ive been a mechanic for awhile and i think i remember the gear at the bottom of the dist.being made of soft metal that can strip gears or brake off causing the dist to either stop turning or "jump time" like a bad timing chain.i seem to remember it happening on the 4.1 motors but if your car is a 4.5 or 4.9 its still basically the same motor internally.
