What causes the spark controller to burn out?


Either engine computer (ecu) or ignition control module. It may have different names like power transistor unit, ICM, ECM etc. Power runs from engine computer to ignition module then that powers the coilpack/coils. Also check the ground connections as they corrode over time. If you replace any units make sure the make a great connection and use any heatsink paste required

Died while driving and wont start


CK your distributor rotor ....pull it off and look in side the hole where it fit on the distributor shaft if it really black in side replace it . If OK then either your ignition module ( inside the distributor a little black block with wires going to both end of it ) or the Stator inside the distributor has shorted out . The stator is kinda hard to change if you don't have the right tools . i think rebuilt distributors from the parts store have gotten a lot cheaper then they use to be ; you may want to change the whole thing a new one will come with a new module and stator

No spark from spark plug wires I think it may be the distributor cap or interior parts under cap like rotor and condensor but dont want to change parts thats are fine i replaced the plugs but still no...


There wrere two types of HEI (High Energy Ignition) distributors used by GM in 1985, one was the original design with the ignition coil mounted in the top of the distributor cap, and the second had the coil mounted seperate from the distributor and used a coil wire.

There is the possibility that the ignition coil is faulty and first check to see if full battery voltage is even getting to the "Pos" (+) positive side of the ignition coil when the key is in the "Run" position, and also if the coil is seperate from the distributor that full battery voltage is getting through the "Pos" (+) or positive side of the ignition coil and over to the distributor ignition module, dis-connect the wire connector from the ignition module and if battery voltage is not present at the connector to the ignition module with the key in the "Run" position but it is present at the "Pos" side of the ignition coil, then the ignition coil is faulty. If battery voltage is present then check the ohms between the high tension terminal (where the coil wire goes on the ignition coil) and the "Pos" terminal on the ignition coil by first dis-connecting the wires from the ignition coil and then test with the "Neg" lead from the ohm meter in the high tension terminal on the ignition coil, and the "Pos" lead from the ohm meter to the the "Pos" terminal on the ignition coil, and the ohm reading should be between 6,000 and 30,000 ohms and if not replace the ignition coil. A faulty ignition coil can also damage the ignition module.

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 could be 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 the ignition module does test out alright then the problem could still be in the pick-up coil/stator, (it can be tested using an ohm meter by dis-connecting the wire connector from the pick-up coil/stator and the ohm reading between the two wires from the pick-up coil/stator should be between 500 and 1500 ohm's, and both of the wires from the pick-up coil/stator should show an open loop or an infinite reading between each wire and ground) and if the pick-up coil/stator is found to be faulty then replace the entire distributor, or the distributor will have to be dis-assembled to install a new pick-up coil/stator.

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.

Let me know if you require any further assistance.

1979 chevy van not getting spark.was running fine day before.turns over fine,getting fuel.could it be the module


First thing is what condition are the distributor cap, ignition rotor, and spark plug wires in?

There is the possibility that the ignition coil located in the top of the distributor cap is faulty and first check to see if full battery voltage is even getting to the "Bat" or "Pos" (+) positive side of the ignition coil when the key is in the "Run" position. Then check the secondary resistance to the ignition coil.

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. 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 the ignition module does test out alright then the problem could still be in the pick-up coil/stator, (it can be tested using an ohm meter by dis-connecting the wire connector from the pick-up coil/stator and the ohm reading between the two wires from the pick-up coil/stator should be between 500 and 1500 ohm's, and both of the wires from the pick-up coil/stator should show an open loop or an infinite reading between each wire and ground) and if the pick-up coil/stator is found to be faulty then replace the entire distributor, or the distributor will have to be dis-assembled to install a new pick-up coil/stator.

What would cause my car to not send spark to the spark plugs


The first thing is do you know when the last time was that the distributor cap, ignition rotor, and spark plug wires were changed?

There is the possibility that the ignition coil is faulty and first check to see if full battery voltage is getting to the "Pos" (+) positive side of the ignition coil when the key is in the "Run" position, and also that full battery voltage is getting through the "Pos" (+) or positive side of the ignition coil and over to the distributor ignition module, dis-connect the wire connector from the ignition module and if battery voltage is not present at the connector to the ignition module with the key in the "Run" position but it is present at the "Pos" side of the ignition coil, then the ignition coil is faulty.

what about the distributor cap?? do you have a spark from the centre lead that comes from the coil??These vehicles also have a factory immobilisor ------ do you have power to one side of the coil??i have a 94 sovereign 4lt as well and a workshop manual somewhere ?? looks like i will have to dig it out
