I Need a wiring diagram for a ignition control module for a 93 Chevy Lumina APV 3.1 engine.?
The wiring diagrams are available online at GM or any other make you want. This will not be the problem however. What you need to do is get a replacement distributor or the plastic connector that broke. I have never been able to find these connectors, plus there will be a lot of the green corrosion on the connectors which can cause further ignition problems. Cut you losses, return the module, and get a completely overhauled distributor for this unit from your local autovalue or somewhere else. Distributors are really easy to replace, just mark them where they come out, and time the motor after replacement properly. Good luck.
What controlled when a spark plug fired before an ignition control module?
Usually a distributor with breaker points or their electronic equivalent.The breaker points formed a normally closed circuit between the battery and primary side of the ignition coil. A cam opened them when a spark plug should fire, causing the coil’s magnetic field to collapse producing high voltage in its secondary side. At that time a rotor connected to the coil high voltage winding would be pointing at a terminal for the correct spark plug.Breaker points and their cam wear from mechanical abrasion so they require periodic adjustment. To avoid that newer cars replaced the breaker points with optically or magnetically triggered electronic circuits.A mechanism using centrifugal force would advance the rotor at high RPMs. A vacuum diaphragm would move the points or electronic trigger advancing timing at part throttle.Intake and exhaust valves are usually actuated by a camshaft which rotates at half the crankshaft speed on four stroke engines as used in most cars.From Contact breaker point.

How do I remove and replace an ignition control module for a 1990 Oldsmobile Cutlass Ciera?
The Ignition module is about from 2 to21/2 inches long.It is located under the distributor cap on the distributor body it self.Black in color and has about 7 electical Blade connections.2-hex head srews hold it in place.Just unbolt it and remove electrical conneectors.Apply jell to the back of new module and install. If this is not a carburated engine I need more info.If no spark condition ,Check water temp sensor for proper connection,as a bad connection = no start.
Only one ignition coil is bad, should I change the rest ones which are in good condition?
Some of these answers are flat effing out EMBARRASSING!First of all, the only answer anyone can give is “MAYBE”, or its cousin “it depends”. I didn't see where you pointed out a year, make, model and engine of the vehicle to even give anyone a real shot at giving a legitimate response.Some vehicles, you really are better off replacing ALL the coils due to design flaws. Depending on the circuit, they can wreck the drivers in the PCM (Ford, Mazda). As mentioned already, if the coils are buried under a plenum, you might consider replacing those that are trapped under it.It's true, some vehicles do not see many coil failures and therefore replacing all or more than just the failed coil may be overzealous.Someone compared coils to lug nuts….WTF! Unbelievable…I just don't even have the words…
Will a faulty transmission control module cause a car not to start?
When you say won’t start, is that meaning will not turn over, or will simply crank and not start, big difference. Transmission neutral switch will prevent engine from turning over, but transmission module is a shift control and will not usually prevent car from starting in my experience. If anything, clean connector contacts for some are located in area which collects road grime, so check connections. If you simply put shift in neutral and try again. Moving shift lever through all positions as you are trying to start will sometimes give you your answer if it starts. You need to be more specific as well as make and model to get accurate answer.In the case of no crank situation, here is a way to analyze your starter control module. Most vehicles have a gear selection indicator in dash, so with ignition on, simple watch indicator as you shift from P park to R reverse to N Neutral and each of 1–2–3–4–5 gear positions if you have the typical select shift transmission option. If the indicator coordinates with your shifter, it is likely not your transmission start module. Always try to start your vehicle in the neutral position as well is an easy way to narrow down problem. If it is a dirty transmission position contact, this may solve your no crank situation, check for bad plug connections as well, this is common problem on many models where location of transmission control module is exposed to elements. Again, there are many issues which can stop an engine from starting, so more specifics and model and options would be needed for more accurate answer.Forced-Success-System.com
"What does an ignition module look like? Where is it located on a 1992 Chevolet S-10 Blazer"?
The module on your truck will be in the distributor. It is a black sort of trapezoid shaped plastic piece, with external wire connectors (external to the distributor cap). It will most likely be secured by two screws. Its function is to control the ignition cycle. It tells the coil when to fire. It replaced points in the older point/condenser style ignition systems. These type of electronic automotive circuits simply fail. They generally work very well and then just not at all. I wish I had better explanation for you, but that's just kinda how they work. You can have them tested at any major auto parts store, but you will need to remove it from the vehicle and take it to them. They will not test it on the vehicle.
How do you know when a crankshaft position sensor is bad in a 89 chevy beretta gt 2.8L?
car is not getting any spark. I have already changed the ignition control module.Car sounds like it might turn over but wont. I was told it could be the crankshaft position sensor
What is wrong with my Chevy,it goes into limp mode,occasionally?
Have a 92 Caprice that drives o.k but out of the blue it will go into limp home mode,It reads code 42,ECM. what is it,it has been in the shop loads of times and they cant sort it. It has a new engine,with less than 500 miles on it, and I cant go 5 or 75 miles without it happening. If I turn off the ignition it resets.And will drive o.k again, for a while.Help,please, its driving me mad.
My 98 ford contour has no spark at all and will not start?
Need to know if your Contour has the 4 cylinder engine or the V-6? ADDED: Thanks for the info. The most common reason for the 2.5L DOHC Duratec engine to have no spark is a failed CKP (crankshaft position sensor) A good test (on this vehicle) is to see if the CEL (check engine light) comes on with the ignition key in the run position, and while the engine is cranking the CEL should go out if the PCM (powertrain control module) is receiving a CKP input! If the CEL does not go out during engine cranking you will need to replace the CKP sensor! ADDED: The CKP sensor is located on the front of the engine (passenger side) down low by the bottom crankshaft pulley and it has a 2 wire connector!
