Two places to look 1. Ignition module, this can be tested at local parts store for free 2.crank position sensor, compare with ohm metere to known good one. Typicaly if cracked- its bad.

Ignition module may be bad. It should be located under the coils, the coils usually plug into the ignition module. Also might be a bad crank or cam sensor

Suggest you check the wiring harness going from the ignition module to the crankshaft sensor, and camshaft sensor, before you check these electronic components. (Ignition module, crankshaft sensor, camshaft sensor)

This small wiring harness is located in close proximity to the engine. Picks up heat, and the insulation of the wires harden over the years. Result can be a break in a wire, or wires, giving a momentary contact between the break, or no contact at all. It's a common thing for that wiring harness to have problems, but usually only known to qualified GM mechanics.

I have a 1995 chevy corsica 2.2 4cyc. The car turns over but will not start.


Yellow spark is usually a sign of a faulty coil, but you have two.
So if the coils are not the problem, it could be not enough voltage to the coils or something else.
The coil fires when the ground connection is removed, in your case the coil fires two cylinders at the same time.
I would check battery voltage to the coils thru the module next.

2006 Suzuki forenza no fire from coil pack


what country? this is the WWW, post country for better answers.......!
Only a scope can see the fast 5mS signals to the coil.
so its either the coil pack or the ECU blown. (wires are always suspect)
you never said , all 4 are dead, or 1 or 2, and how many packs.
some non usa cars have wasted (2pak) spark , not 4 COPS.
state what cylinders have spark and which don't.
there are only 2 ways to fix cars.
1: guess and swap parts
2: use tools. my guess is you dont have them.
some coil packs are active (ignitor inside) others just a coil.
you can test the restance of the coils, with a DMM , ohm meter.
if active you cant.
the fsm covers this on all cars.
https://suzukipitstopplus.com/category/3-suzuki-service-manuals.aspx
the 2006 Forenza as delivered to USA has.....
has a large single, dual wasted spark coil pack. (brick)
it does in fact have , internal ignitor drivers. inside. so can not be tested
with and ohm meter on the primary side. but can be on the secondary
you do know how to test wasted spark , right, All spark plugs must be
attached and grounded for the coil to work,
1and 4 are shared.
2 and 3 are shared.
so to test , you must keep the spark plugs (both or all 4 is best)
attached and the shells of spark plugs grounded.
there is a fuse that powers the coil pack. (usa)
the fuel pump relay sends power to the coil pack.
so of that is dead,so will be the pack. (im reading FSM as it type)
get an FSM.
pin 2 on coil pack is power. 12v.
pin 1,is spark 1&4 drive (fast ECU pulse)
pin 3 is 2&3 coil drive. (scope can see it)

recap, are you using the correct wasted spark testing method.
and are all 4 spark plugs dead.?

How can I change the spark plugs and wire how do I know if the coils are bad


intake manifold gasket may be bad,if the coils were bad you would get no spark and no fire i doubt its your plugs

I have a 96 Chevy Corsica and it won't start.... I


If you have a healthy spark (a blue snapping spark), it would not be a problem in the ignition system or the module. An orange, weak, or intermittent spark could point to trouble in the ignition.
I would check the timing on it, maybe it is a timing chain problem. It should have fired and ran a bit with the starter fluid. The fact that it didn't, even with a good spark, well, probably needs a little shop time investigating. Jumped timing from a worn chain? Low compression in one or more cylinders? A couple of things you need to consider.
Good luck.

I have a 92 corsica 3.1 all of a sudden it wont start. im getting a small spark from 4 and 6 but nothing from 2. any ideas? abot 2 years ago had to chg coil packs and icm. could either have fouled out...


if the battery voltage is not at full voltage this can cause a poor spark.this needs to be checked first as without proper voltage all testing is not accurate,i`m guessing that you have no check engine light on the dash when it was running so this eliminates a possible code set in the computer.if you check the connections at the icm and make sure they are clean as they get alot of debris thrown at them aver the year because of were they are mounted.were these new components when you changed them or used,this is a common problem with this system.you don`t say if cylinders 1-3-5 have any spark of any kind.it sounds like you may have a bad icm as you say cylinders 4-6 are weak spark and nothing from #2.without checking this out it sounds as the crank and cam sensor is working or you wouldn`t have any kind of spark.this narrows it down to icm or poor coils however it is very rare that 3 coils would all of a sudden go bad,again this indicates a bad icm

My 92 dakota is not getting any spark


Engine Fails To Start

The "Checking For Spark'' test should be performed prior to this test.

This is a basic test of the ignition system that systematically examines the battery, the coil, the engine controller, and its wiring harness and connections; the most likely culprits in a no-start condition at this stage.
88472304.gif

Fabricate this special jumper with a 0.33 MF capacitor in-line to test the ignition coil
Click to Enlarge

  1. Unplug the ignition coil harness connector at the coil.
  2. Connect a set of small jumper wires (18 gauge or smaller) between the disconnected harness terminals and the ignition coil terminals.

  1. Attach one lead of a a voltmeter to the positive (12V) jumper wire. Attach the negative side of the voltmeter to a good ground. Measure the voltage at the battery and confirm that enough current is available to operate the starting and ignition systems.
  2. Crank the engine for five seconds while monitoring the voltage at the coil positive terminal:
    1. If the voltage remains at zero, diagnosis of the fuel system should be performed. Also check the engine controller and auto shutdown relay.
    2. If voltage is at or near battery voltage and then drops to zero after one or two seconds of engine cranking, check the engine control module circuit.

WARNING

The ignition must be turned OFF prior to unplugging the engine controller connector. If it is not, electrical surging could occur causing damage to the unit or other electrical components in the vehicle.

  1. If the voltage remains at or near battery voltage during the entire five seconds, turn the ignition key OFF. Remove the 14-way connector on 1989 models, or the 60-way connector on 1990-96 models at the engine controller. Check the 14-way or 60-way connector for any spread terminals.
  1. Remove the test lead from the coil positive terminal. Connect an 18 gauge jumper wire between the battery positive terminal and the coil positive terminal.
  2. Make a special jumper cable (see illustration). Using the jumper MOMENTARILY ground terminal 12 on the 14-way connector (1989), or terminal 19 (see illustration) of the 1990-96 60-way connector. A spark should be generated at the coil wire when the ground is removed.
    1. If a spark is generated, replace the engine controller computer.
    2. If no spark is seen, use the special jumper to ground the coil negative terminal directly. If spark is produced, repair the wiring harness for an open circuit condition. If spark is not produced, replace the ignition coil

Testing

This procedure requires an ohmmeter to test the coil packs for primary and secondary resistance (specifications are given for an ambient temperature of 70-80°F/21-27°C).
88472320.gif

The two coil packs contain five independent coils, which fire paired cylinders (shown numbered)

  1. Disconnect the negative battery cable.
  2. Determine the manufacturer of the coil. It should be labeled either a Diamond or Toyodenso.

  1. Check the secondary resistance of each individual paired coil by connecting an ohmmeter across the coil towers. This must be done between the correct cylinder pairs: 3/2, 7/4, 1/6, 9/8, or 5/10. Resistance for a Diamond coil should be 11,300-15,300 ohms. For a Toyodenso manufactured coil pack, resistance should be 11,300-13,300 ohms.
88472323.gif

Use an ohmmeter to check secondary resistance as shown

  1. Check the primary resistance of the front coil pack by attaching an ohmmeter between the B+ coil terminal and either the right (cylinders 3/2), center (cylinder 7/4), or left coil (cylinders 1/6) terminals. Resistance for a Diamond coil should be 0.97-1.18 ohms. Resistance for a Toyodenso coil should be 0.95-1.20 ohms.
  2. To test the primary resistance of the rear coil pack, attach an ohmmeter between the B+ coil terminal (see illustration) and either the right (cylinders 9/8), or left (cylinders 5/10) coil terminals. Resistance for a Diamond coil should be 0.97-1.18 ohms. Resistance for a Toyodenso coil should be 0.95-1.20 ohms.

I have a 2003 Chevy Blazer, just bought it, after driving it about 30 miles the service engine soon light came on. Its misfire on cylinder #4. Plugs and wires are good. Whats the problem.


it can be the coil for #4 each cilynder has his own coil also try to check make sure the coil is installed properly it happen to me I replaced spark plugs on my own blazer and service engine light came on #1 cilynder was not working so I did took the coil of again and make sure it was ok try to get back in place and problem fix if still doing then you can swap coils but not wires that connect the coils and see if your code reads different spark plug # if so then is time for a new coil
