Hi I have a 2003 Suzuki liana, Iv put in an 2006 Suzuki engine into it and won't start and has no spark can you help me?


Did you disconnect the battery when you did the work? I am guessing you probably did. Your anti-theft system is invoked.

Disconnect the battery for 2 hours. Bridge the connectors for 5 minutes to fully dissipate any residual power. Put the key in the ignition, reconnect the battery sharply. Leave for 15 minutes to initialise.

Engine is turning over,but not starting


first, test for spark at the ignition coil. take the power cable that connects from the ignition coil and disconnect the end at the distributor. hold the bare connecting end a fraction of an inch away from a metal paqrt of the cars frame and attempt to start. if the ignition coil is good, it should throw a spark. if the ignition coil sparks, next check your spark plugs for oil, grime, black or white discoloration on the spark tips (that point inside the engine). if there is a lot of build up or discoloration, replace the spark plugs. if this does not solve it, change your distributor cap, and if this doesnt slove it, change your spark plug wires.

Hey there,i have a 1991 msuatng LX with the 2.3L ho engine running an 8 plug head. it sounds like i may have a misfire of some sort or my timing may be out but im not sure how to tell, could someone give...


Insert each wire on the proper terminal of the ignition coil. Ensure that the coil boots are fully seated and both locking tabs are engaged. The terminals are identified on the ignition coils. Install wires as shown in the illustration. The 2.3L firing order is 1-3-4-2 for both ignition coil assemblies.

Distributorless Ignition System In the distributorless ignition system (DIS), all engine timing and spark distribution is handled electronically with no moving parts. This system has fewer parts that require replacement and provides a more accurately timed spark. During basic operation, the EEC-IV determines the ignition timing required by the engine and a DIS module determines which ignition coil to fire.

Components
The distributorless ignition system (DIS) for the 2.3L twin spark plug engine consists of the following components:
  • Crankshaft timing sensor
  • DIS module
  • Two ignition coil packs
  • Spark angle portion of EEC-IV
Crankshaft Timing Sensor
The crankshaft timing sensor is a dual hall effect magnetic switch, which is actuated by the dual vane cup on the crankshaft pulley hub assembly. This sensor generates two separate signals, PIP (profile ignition pick-up) and CID (cylinder identification). The PIP signal provides base timing and RPM information, while the CID signal is used to synchronize the ignition coils. Initial timing (base timing) is set at 10 degrees BTDC and is not adjustable. Ignition Coil Packs
Two ignition coil packs are used for the 2.3L dual plug engine. The two ignition coil packs are triggered by the DIS module and are timed by the EEC-IV. Each coil pack contains two separate ignition coils for a total of four ignition coils. Each ignition coil fires two spark plugs simultaneously, one spark plug on the compression stroke and one on the exhaust stroke. The spark plug fired on the exhaust stroke uses very little of the ignition coils, stored energy, and the majority of the ignition coils, energy is used by the spark plug on the compression stroke. Since these two spark plugs are connected in series, the firing voltage of one spark plug will be negative with respect to ground, while the other will be positive with respect to ground. Refer to thePowertrain Control/Emissions Diagnosis Manual for additional information on spark plug polarity. DIS Module
The main function of the DIS module is to switch between ignition coils and trigger the coils to spark. The DIS ignition module receives the PIP and CID signals from the crankshaft timing sensor, and the SPOUT (spark out) signal from the EEC-IV module. During normal operation, PIP is passed on to the EEC-IV module and provides base timing and RPM information. The CID signal provides the DIS ignition module with the information required to switch between the coils for cylinders 1 and 4 and the coils for cylinders 2 and 3. The SPOUT signal (from the EEC-IV) contains the optimum spark timing and dwell time information. The dwell time is controlled or varied by varying the duty cycle (duration) of the SPOUT signal. This feature is called CCD (computer controlled dwell). Therefore, with the proper inputs of PIP, CID and SPOUT the DIS ignition module turns the ignition coils on and off in the proper sequence for spark control. CID is also sent to the EEC-IV micro-processor to allow for Bank to Bank fuel control. Failure Mode Effects Management
During some DIS system faults, the Failure Mode Effects Management (FMEM) portion of the DIS ignition module will maintain vehicle operation. If the DIS ignition module does not receive the SPOUT input, it will automatically turn the ignition coils on and off using the PIP signal. However, this will result in fixed spark timing (ten degrees BTDC) and a fixed dwell time (no CCD). If the DIS ignition module does not receive the CID input during engine cranking, random coil synchronization will be attempted by the module. Therefore, several start attempts (cycling the ignition from OFF to START) may be required to start the engine. If the DIS module loses CID input while engine is running, the module will remember the proper firing sequence and continue to fire to maintain engine operation. Dual Plug Inhibit
Dual Plug Inhibit (DPI) is a function of the EEC-IV that is only used when the vehicle is being started at temperatures -7° C (20° F) and below. During engine cranking, the EEC-IV will only fire the spark plugs on the right hand side of the engine. When the engine has started, the EEC-IV will send a signal to the DIS module to start normal dual plug operation. Ignition Diagnostic Monitor
The Ignition Diagnostic Monitor (IDM) is a function of the DIS module. The DIS module sends information on system failures to the EEC-IV which stores the information for diagnostic self test. The IDM signal also is used to drive the vehicle instrument tachometer, and test tachometer for system

Just wondering if you have a breakdown diagram for a 1992 dodge colt 1.5l distributer


I do not have a breakdown diagram for a distributor, but just the firing orders and description of ignition system for the Dodge Colt and related models (based on Chilton manuals) if that's what you're looking for: FIRING ORDERS Fig. 1: 1990 1.8L SOHC Engines Firing order: 1-3-4-2 Rotation: clockwise 84182009.gif

Fig. 2: 1.6L DOHC Engine Firing order: 1-3-4-2 Distributorless Ignition 84182010.gif

Fig. 3: 2.0L Engine Firing order: 1-3-4-2 Rotation: clockwise 84182011.gif

Fig. 4: 1.5L Engine Firing order: 1-3-4-2 Rotation: counterclockwise 84182012.gif

Fig. 5: 1993 1.8L Engine Firing order: 1-3-4-2 Rotation: counterclockwise 84182013.gif

Fig. 6: 2.4L Engine Firing order: 1-3-4-2 Rotation: clockwise 84182014.gif

To avoid confusion, replace spark plug wires one at a time. --- Distributor REMOVAL & INSTALLATION Although the distributor can be removed from the engine no matter which cylinder is about to fire, it is a good idea to have number one cylinder at TDC before distributor removal. 1.5L, 1.8L, 2.4L SOHC Engines
  1. Disconnect the negative battery cable.
  2. Disconnect and tag the spark plug wires from the distributor cap.
  3. Disconnect the distributor harness connector.

    Fig. 4: Ignition system for the 2.4L engine 84183004.gif

  4. Loosen the distributor retaining bolt and remove the distributor from the engine. To install:
  5. Rotate the engine until No. 1 cylinder is at TDC on its compression stroke. NOTE: Be careful not to turn it to the No. 4 cylinder TDC on its compression stroke by mistake.
  6. Align the distributor housing and gear mating marks.

    Fig. 7: Distributor installation for the 1992-93 1.8L engine 84183007.gif

  7. Install the distributor into the engine, while aligning the fine cut (groove or projection) on the distributor flange with the center of the distributor mounting stud.
  8. Install and tighten the distributor retaining bolt.
  9. Reconnect the distributor harness connector.

  10. Install the distributor cap and spark plug wires.
  11. Reconnect the negative battery cable.

93 jeep cherokee , iv got spark at the coil but not at the plug just replced cap, roter, wires, but still notheing got any ides ?


Coil may be producing low voltage (KVs) to where it makes enough energy to snap out of the coil tower but then supressed as it travels down the high tension leads finally to the plug. Incidentally spark plug leads should have about 10k ohms of resistance per foot.I good coil will jump spark at least a half inch if you pull the wire off the cap and produce this much air gap
