A timing light may work. If no flash then no spark.

No spark? Anywhere to check?


Check inside the distributor for loose wire connections, and signal from igniter.

2011 swift 1.5 no injector pulse no spark


blown fuse. ; is first, as per always.
2nd is scan it, did you scan it yet? that is always 2nd.
all efi engines, all ECU , all cut injectors for (noid lamp test dead?)
you said pulse,does that mean fuel pulse or electronic pulse to injector coil..... ? all injectors dead. or just 1. same for spark.
toss coin land, noid dead. all noids
loss of. NOID signals.!
1; spark
2: lose of CMP or CKP signals (cam or crank senders)
3: ecu sees wide open throttle it cuts fuel 100%
4: ecu bad, is CEL lamp dead key on? scan it.

Vw golf 1 timing


This engine is fully electronically controlled, you must do a fault code test, once you have the fault codes you do the required fault codes testing per the factory service manual and replace or repair the problem(s) that caused the loss of spark.

VW golf cabriolet do not give petrol. The petrolpump is ok...? Codes are checked (problem, HALL something, but has it something to do with the petrol?


Hi there,

I suggest you do a fuel pressure and volume test also.

But first, you need to ensure you have good spark. Make a spark tester by gapping an old spark plug to 0.200" and sticking it on a plug wire. Lay it on a metal ground and crank the engine over and see if there is spark. If no spark, then the problem may lie in the ignition system.

Check for battery voltage at the positive side (15) of the coil with the key on. If there is no voltage check the yellow wire from the ignition switch. If there is power there you have a break in the wire somewhere in between.

If you have power to the coil, stick your spark tester in the end of the coil wire.

Then, with the key on, hook a jumper wire to the negative (1) side of the coil and MOMENTARILY ground it. If you get a spark, then the Hall Effect sensor in the distributor is either bad or not getting power.

At this point I would recommend getting a Car Service Manual from the reference section of your local public library. It has a more detailed testing procedure for the testing the Hall Effect sensor and ignition module. It is much too long for me to describe here in this forum.

Good luck...

Lost inj. pulse need to know where the ecm gets crank position from. if from dist.how does it locate #1 1985 crovette


Lost injector pulse. First injector power is supplied by (IGN+) or fues block ,The injector are multi-potr not individual they are fired together,not individually, Now if you lost injection pulse youll need to inspect the Distributor,the pick up is highly suspectable to terminal corrosion, it corrodes easily,so be ready to replace the pick up with a module, (this is spark I know we are on Injector), Do you have spark, then leave this alone, Test injector pulse not at the injector because again its bank fire or group fired You ll need to test thes the connector harness connector,of the injectors.As long as there is spark you should have injector pulse from the injector sub harness connector make your way to the ECM , The ECM controls the energizing of the injector with a transitor or quad driver,they are synchronized to primary ignition . Here a solution if no spark correct for spark. Its either a Distributor pick up failure with ICM module.Do this only is you have no spark.If you have spark and no Injector ,replace ECM

I have a Ford F-150 1990 Model. It doesn't seem to be getting fire to the sparkplugs. I just replaced the spark plug wires and spark plugs. What could be the problem? It is a V8.


Sounds like its a distributor. To test if its sparking at all take the plug wire and hold a screw driver and see if it arcs to the screw driver when you crank it. but heres the best way to diagnose it on your vehicle follow the following steps and let me know from there what happens.

Steps
1 Remove the spark plug wires one at a time and insert a small screw driver into the wire.(SEE WARNINGS) Be careful as you don’t want to get shocked with 60,000volts. Hold the wire so that the screw driver is 1/8” away from the engine. Have someone crank the engine and watch for a good white spark. If you have a good spark on all wires look for a problem with timing or something else. 2 Remove the distributor cap. Have someone crank the engine over with the distributor cap removed and observe if it is turning? That is if it has a distributor cap, some newer cars don’t have one. If the distributor is not turning then likely you have a broken timing belt or chain. 3 Turn the ignition key on but don't crank the engine. Locate the positive or power wire attached to the engine coil. Using a test light check for power. If this has power, then the wiring from the ignition switch is OK. 4 Locate the negative or ground wire attached to the engine coil. Using a test light check for power. This sounds strange however, one end on a good battery ground and the other on the negative wire attached to the engine coil. The test light will light up indicating power on the negative side of the coil with the key on and engine off. 5 Have someone crank the engine while watching the test light. If you observe the test light flickering when cranking the engine and you have no spark, either the coil wire is faulty of the coil is dead. Test these using an Ohm meter.# If no flickering or pulsating was observed then check continuity in all primary circuit wiring for opens. This is the negative wire back to it's source, the ignition module. 6 Check the pulse generator in the distributor if it has a distributor cap. Some newer cars don’t have one,and if it doesn’t then the ECM or computer sends signal via the crankshaft position sensor and the camshaft position sensor. 7 With the engine in non-running condition connect your A/C voltmeter to the pair of wires at the pulse generator and crank the engine. You are looking for an A/C signal that makes 4-6 volts of A/C. If this is observed then the ignition module is dead or has a bad ground. If no A/C signal is observed then you have a dead pulse generator in the distributor. 8 Know that if this part of the primary ignition tests OK then check wiring to ECM pinouts for opens. If wiring tests are OK. Suspect the ECM or computer as a last resort. edit
Warnings
Be careful as you don’t want to get shocked with 60,000volts. be careful when checking the leads for sparks with a screwdriver doing it this way can cause very expensive damage on newer engins best use a spare spark plug or a proper tester for this job

No spark in my 1999 silverado 4x4 4.8 engine


Crank engine with distributor cap removed, is it turning?
(That is if it has a distributor cap, some newer cars don’t have one)is it turning?
Broken timing belt or chain?

Are you getting power to the + positive side of the coil (small wires) with key on ? Hint; I use a needle pushed into the back of the plug so as not to damage the wiring.
If you have power then wiring from the ignition switch is OK. It usually is.
Hook your test light to the - negative side of the coil (one end on the - terminal and the other end on a ground). You should have power on the - side of the coil with the key on and engine off.
Crank the engine while watching the test light. Get a flashing signal at the test light when cranking?
If so and you have no spark the coil is likely dead.(don’t rely merely on resistance tests for a coil, a weak coil can test ok for resistance but still give no spark.It happens but is unusual. I learned this the hard way!)
No flashing signal?
Check continuity in all primary circuit wiring for opens.
If they are good,
It is time to check the pulse generator in the distributor. (That is if it has a distributor cap, some newer cars don’t have one, if it doesn’t then the ECM or computer sends signal via the crankshaft position sensor and the camshaft position sensor)
With the engine in non-running condition connect your A/C voltmeter to the pair of wires at the pulse generator and crank the engine. You are looking for an A/C signal that makes 4-6 volts of A/C. Got this? If so the ignition module is dead or has a bad ground. If not (more likely) you have a dead pulse generator in the distributor.
If you have three wires in the distributor signal wire you have a Hall effect sensor. I forget how to test that one. (Chrysler stuff)


If this part of the primary ignition tests ok then check wiring to ECM pinouts for opens.Wiring tests ok.ECM as last resort.
Hope this helps...........
