1998 gmc Sierra firing system


701d6c31-22de-486c-b704-98411f6a9f82.jpgdba42bb6-2f2d-4771-b4a1-0c9698991bb2.jpg5be8e0a6-186d-40d0-b2df-ec5869770d9e.jpgI am not real sure of the question. Module, distributer and starter ? The starting circuit doesn't really connect to the distributer and as far as a module goes, it's not really connected to the distributer and has 4 wires going to it not 3. You said 3 wires and distributer in your question so I'm gonna try and help you and hope I am understanding what you are trying to ask. You didn't mention your engine size and the picture looks small but it really doesn't matter if you happen to have the 4.3 liter engine. The wiring is pretty much the same. The wire colors may be the same V-6 or V-8 Engine. Now the distributer does have 3 wires coming from the distributer (pink, pink with a black stripe and a brown with a white stripe). Those are for the cam shaft position sensor which is mounted on the distributer. I am guessing the engine won't start but does turn over and your not getting any spark at the spark plugs (kinda going by your question you wrote. If this is what is happening then yes the ignition control "Module" correct however that is mounted on the right (passenger) side of the engine basically on top of the valve cover. Like I said it has 4 wires going to it and if this is faulty you will not get any spark. In the picture with the engine, where I put the red arrow at is the general location of the module. The other 2 pictures are the wiring diagrams for the entire starting circuit and the wiring for the cam shaft position sensor. If I'm way off of what your question is you can reply here with more details in your question or feel free to email you directly at csautomotivecars@att.net Hope I was able to help a little bit anyway.

Quest head lights won't turn off


The body computer controls the headlight relays based on input from the switches. There is a relay for high beam and one for low beam in a power distribution module in the engine compartment.
I don't know if the relays are available without buying the entire module. One of them could be stuck on.
You may need a shop manual to get the wiring diagrams and procedures to test the circuits.
In the mean time you should be able to pull the 50amp fuse for the headlights.

The car turns over like it is going to start but won't. It is still firing, has good battery, alternator and gas in it. It is a 1996 plymouth neon. Started fine when I went to work this morning, b


tell individual working on it to check the crankshaft sensor voltage and signal when it wont start also check the fuel pressure and cam sensor, these are all possible problem with that particular car. it also has wiring issues that an expert tech would have to diagnose

F150 ignition (won't Start)


If it turns over but just won't fire and the timing sounds fine when it does run you might consider your ignition switch.  Does it sound like it wants to fire but only just when you let go of the key?
