You may need to adjust the electrical part of the switch. I am first assuming that you didn't have any other problem with your truck other than needing a new lock cyl. First you need to take the cover off your column buy removing the screws from the bottom. You will see the electrical half of the switch with all the wires coming out. Loosen the two mounting screws just enough for you to slide it up and down the column, while hanging onto the switch, turn the key and pull the switch towards you untill the truck just starts to crank over. holding it at this point tighten down. If you still have this trouble your switch is most likley shot.

I installed a new steering column in my 2004 Pontiac sunfire and now it will not start. It tries then I beta back fire.


Anti-theft system isn't allowing it too .
The Passlock™ System is provided in order to prevent vehicle theft if the ignition lock cylinder is forced to rotate or the ignition switch is operated while separated from the ignition lock cylinder case. If starting is attempted without authorization from the Passlock™ System, the powertrain control module (PCM) will disable engine starting. Start disable may be in the form of fuel disable or starter disable, depending on engine application.
The components of the Passlock™ System are as follows:
• The ignition lock cylinder and key
• The ignition lock cylinder case, including the Passlock™ sensor
• The ignition switch
• The body control module (BCM)
• The security indicator on the instrument cluster
• The powertrain control module (PCM)

What makes a 1988 F150 trucks ingnition stay engaged


Most likely the ignition switch or the rod in the steering column is sticking and keeping the switch engaged, possibly the ignition lock cylinder is sticky too. Easy to get lock cylinder out with a small punch that depresses a pin when the lock cylinder is in the run position, look under the steering column by the switch for a hole to poke the punch into and then pull out the lock cylinder.

My 2003 saturn ion will turn over but willnot start


You may have two issues, one with starting and running while the other may be ignition lock cylinder related. You may be able to try using the spare key if you have one otherwise its recommended to have one made by Saturn and try it before determining that its a worn out lock cylinder. Then Saturn may be the best choice to at least configure a new lock cylinder with the original keys to match. The lack of engine firing up may be a simple cps failure.

The engine turning over but never firing up may be related to the crank position sensor (CPS) as long as you don't see the security light flashing in the speedometer or tach. The security light flashing would mean the factory anti-theft deterrent system is preventing engine running by disablng the fuel pump. No fuel pump = no engine run. Determining a faulty cps is by way of observation - the spark from the ignition system is observed. Remove the spark plug wires, noting the firing order carefully, from the coils and have someone crank the engine over so you can watch for expected sparks across the coil towers. A lack of sparks usually means a failed cps as the only other failure would be the ignition module that the two ignition coils mount onto. The cps is mounted behind and above the starter with one 10mm bolt. You can buy it from any auto store stocking it.

Ignition on and nothing happens, checked battery and is charged checked all fuses and breakers and all are ok, got underneath car and shorted across the starter solenoid end the engine would turn over but...


You may have a security system problem (Most likely caused by an ignition lock cylinder fault)

Is your SECURITY light flashing?

If so, do this:

Turn the ignition switch to the START position then release the key, leaving it in the RUN position.
Wait approximately 10 minutes untill the security light stops flashing, then without turning the key off, turn it to the START position again. It should start. If it does, then you should probably replace your ignition lock cylinder. The problem will gradually get worse until this method no longer works.

Distributorless Ignition System General Information This vehicle uses two different types of ignition systems. The 3.7L, 4.7L, and 5.7L engines do not use a conventional distributor. The 5.9L engine uses a conventional distributor. The ignition system is controlled by the Powertrain Control Module (PCM) on all engines. Procedures in this section are for the 3.7L, 4.7L, and 5.7L engines; please see the section on Distributor Ignition Systems for procedures for the 5.9L engine.
Distributorless ignition systems (EI) are used on many current engines. This system uses the waste spark method for distributing secondary voltage. In a waste spark system, an individual coil is used to fire one pair of engine cylinders simultaneously. These cylinders are known as companions, since each of their pistons is at TDC at the same time. On a typical V6 engine for example, cylinder 1 is at TDC compression while cylinder 4 is at TDC exhaust. This is also true of cylinders 2 and 5 as well as cylinder 3 and 6.
The cylinder on the compression stroke is known as the event cylinder, while the cylinder on the exhaust stroke is called the waste cylinder. Since secondary resistance is very low in the cylinder on the exhaust stroke, little voltage is required to fire the plug. For this reason, the majority of available voltage is consumed by the cylinder on the compression stroke.
One spark plug is attached to each end of the secondary coil winding via the spark plug wires. This series circuit arrangement causes one of the plugs to fire in a forward direction (center electrode to outer electrode), and the other spark plug to fire in a reverse direction (outer electrode to center electrode). The firing voltage requirements on the waste spark ignition are significantly greater than a traditional ignition system primarily because it takes 30% more energy to fire a plug reverse polarity. When a spark plug is fired backwards, it fires from the outer electrode to the center electrode. This is a high resistance path since the electrons do not flow as easily from a cold, dull surface such as the outer electrode to a hot, sharp surface like the center electrode.
Since the coil and plugs are arranged in a series circuit, a typical plug gap of .050" results in a total gap of .100" for the whole circuit that includes two spark plugs for the companion cylinders. The waste spark can overcome this added resistance by producing high secondary output voltages due to low resistance in the primary winding. Another reason higher secondary ignition voltage is required is cylinder pressure; specifically, the lack of it. Generally, event cylinders require 10 to 12-kV to initiate current flow across the spark plug gap, while only 2 - 3-kV is needed to fire the waste cylinder. Therefore, the air gap in the waste cylinder creates no more resistance than the rotor gap does in a conventional ignition system.
There are two different methods used for coil trigger. One method sends the crankshaft sensor signal directly to the ignition module to activate the coils, while the other sends the crankshaft sensor signal to the PCM and the PCM controls ignition operation either directly or through a separate ignition module.
Waste spark ignition advantages
  • It has fewer components than conventional distributor-type ignition systems.
  • No mechanical adjustments to set ignition timing.
  • No mechanical load (turning the distributor shaft).
  • No unwanted timing variations caused by gear lash or other worn distributor components.
Another advantage of waste spark is longer coil life. To illustrate this point, consider a six-cylinder engine with conventional ignition. At 3000 RPM, the coil must fire 9000 times per minute. This is calculated by dividing the engine speed by 2, since the cam turns at half crank speed, and then multiplying the distributor RPM by the total number of engine cylinders.
In contrast, the coils on a six-cylinder engine with waste spark only work a third as hard. This is because there's a coil for every two cylinders and each coil fires every crankshaft revolution. This means that at 3000 RPM, the coils only fire 3000 times per minute. This allows each coil to operate with less dwell (time that the coil is energized), resulting in less heat buildup and longer life.
Coil Over Plug System The coil over plug system was developed so that spark and spark timing could be better controlled on an individual cylinder basis. Each cylinder has an ignition coil mounted directly above the spark plug on the cylinder head cover. A short suppresser/connector replaces the spark plug wire and links the coil to the plug. There are different methods used for primary triggering. Some manufacturers use a combination coil/module, which means each coil has its own control circuit that is activated by the PCM. Others use remote mounted modules to trigger the coils.
Each individual coil is allowed to saturate while all other cylinders fire. For a V-8 engine, this allows a period of seven firing events for coil saturation, compared to three events for the same V-8 engine with a waste spark system. The coil over plug system also benefits from a minimum amount of energy lost, due to the resistance of spark plug wires.
Coil Near Plug System The coil near plug system also features multiple ignition coils. An ignition coil/module is mounted in proximity of each cylinder. There is a short length of spark plug wire between the coil and the spark plug.
Each ignition coil/module has its own control circuit and is activated sequentially by the PCM. All timing decisions are made by the PCM. This includes both ignition timing and duration of the spark.

What is the firing order for a 2004 dodge durango


The firing order is a sequence of ignition time when the engine cylinders deliver their power-strokes starting with the number-one cylinder. If this sequence is faulty or arranged disorderly, the engine may not start at all, and if it does start, it may does so hesitatingly, or not run enough well to enable it to drive-or simply lacks the power to move. A waste of gas, and unecessary tear and wear on the engine and its critical components ultimately result. Once the firing oder is correc and in proper sequence, the engine should starts easily and promtly, running as quietly as posiible.

For Dodge 2004 Durango firing-order:
All 6-cylinder K 3.7L MFI SOHC distributorless ignition:
1-6-5-4-3-2 (front 2-4-6) (back 1-3-5)

All 8-cylinder N 4.7L SFI (including HEMI 4-WD)
1-8-4-3-6-5-7-2 (front 2.4.6.8) (back 1.3.5.7)
(distributorless ignition)
It is also a good thing to try and compare the thread lenghts of the old spark-plugs being replaced with the new.

Need firing order and, I need to know what side the number one piston is on?


To avoid confusion, remove and tag the spark plug wires one at a time, for replacement.

The 3.5L (VIN H) engine's unique ignition system has the ignition coils directly over each plug. No spark plug wires are used.
If a coil is replaced on any of the 3.1L, 3.4L or 3.8L engines, it may not be numbered, as is the factory coil. For this reason it is imperative that you label all wires before disconnecting any of them. Also, before removal, compare the current wiring with the accompanying illustrations. If the current wiring does not match, make notes in your guide to reflect how your engine is wired.
