Sounds like you have a wire grounding out, look for a relay that might be getting hot and then cools

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

I have a 1995 f150, 4.9 automatic. I have recently put in a new coil, a new ignition control module and a new distributor cap but I don't get ant spark from the coil. What could it be?


Check for power and ground at the coil. If you have it. Then I would have the ignition module checked, you could have bought a bad one. It happens.

No spark from new coil


Sounds like the problem lies in the profile Ignition Pickup (PIP) i.e Crank Sensor or in the Ignition Control Module (ICM), once the ICM gets the PIP signal, it starts to switch the Ignition Coil on, Once the Ignition Coil gets this switching signal, it starts to Spark away, I think you are not getting signal from PIP to ICM to get spark. I did a quick search online and if you do need to replace your Ignition Control Module this site looks like it has cheap prices, free shipping and great reviews http://www.buyautoparts.com/ignition-control-module.html

97 pontiac transport no power to ignition module


Not sure if I am following you right.
The engine has 3 coils that fire the plugs. The coils are mounted on a module that provides voltage and ground to the coils.
The module gets power from a 20amp fuse marked "Inj" for injector.
The computer controls the module based on info from the various sensors.
A mechanic would do a pin test on the module to diagnose a no spark condition.

89 vette, 48k, car starts fine, runs about a minute or 2, then shuts down, then wont restart, probably vats, after a few minutes, starts right up only to do the same thing.


Sounds like ignition control module (small plastic piece in bottom of distributor). When it gets warm it's shorting out. Easy fix, disconnect battery, pull cap & rotor - gin module is 2 screws in bottom of distributor and 4 wires - replace wires in exact order and coat bottom of middle with dielectric grease, replace rotor, cap & connect battery NEGATIVE CABLE LAST!

After driving for 45 minutes the car starts hesitating, putting, as if its not getting gas, then shuts off.I let it sit for 20 minutes its fine for another 25 to 45 minutes


That is the classical sign of a control module over-heating or an electric fuel pump that is faulty.

The ignition module 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 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.

Where is the emergency fuel cut off switch located?


The neon don't have one, check the fuse and relay's. The fuel pump is also controlled by the Auto Shut down relay (ASD). The power supplied to the fuel pump. Ignition coil, fuel injectors, and parts of the power module is controlled by the logic module through the Automatic Shutdown Relay (ASD). The ASD relay is closed (allowing power to flow through it) when the ignition is first turned on. If the signal from the ignition reference is lost while the engine is running  the logic module cuts power to the ASD, which in turn removes power from the fuel pump, ignition coil, injectors and those parts of the power module.  This causes the engine to shut down. Good luck and hope this helps.

1991 lesabre wont start after shutting down. If it sits a few hours starts up great again. changed plugs, plug wires, coil pack, and Ignition control module but still same problem. ran a little rough but...


Best to do a fuel pressure test, pump might be weak and dosent show up until it gets gets warm. Best to do the test after it quits again when pump is at its hottest. If you havent done it yet chg. fuel filter too.
