No Spark. Car cranks, but no spark from ignition coil.

Testing a crankshaft sensor that way wont always work because everything changes when the sensor is in operation. It does sound like it is out though. Here is a guide that will show you what you are in for when changing it out with some diagrams (below) on how it will be like on your car.

Next, with the key in the run position you should have battery power to the white wire with a red stripe at your coil.Also black wire with a red stripe should have a pulsing ground while cranking the engine?Check for the pulsing ground with a test light that will check your coil inputs to see if the coil is getting what it needs.

Here is a generic guide as well

Please let us know what happens so it will help others.

So there are two wire inputs into the coil?If so one is a constant power and the other is a pulsing ground while cranking that is what causes the coil to spark . also with the distributor cap off and cranking the engine the rotor on the distributor spins while the engine is cranking?

Here is a guide and some ignition system wiring diagrams to help with the testing.

I gave both 4 and 6 cylinders just in case.

Cheers,

It sure sounds like the crankshaft angle sensor is bad. I would try replacing it they go bad all of the time.

Here is a the Denso sensor on Amazon for $53.00

ENGINE DOES NOT START, REPLACED IGNITION CONTROL MODULE

Complaint
The customer states the engine will not start.

Cause
Confirmed the customer's complaint and found the engine did not start. Performed a visual inspection of the fuel system and ignition system components, but found no obvious faults. Removed the spark plugs and performed a visual inspection, but found no obvious faults. Connected an inline spark tester to the ignition coil secondary lead, started the engine, and found the spark was intermittent. Used a multi-meter to measure the resistance of the ignition coil and found the measured resistance was within specifications. Connected a lab scope to the ignition coil primary signal circuit, started the engine and found an erratic signal. Performed a visual inspection of the ignition control module wiring harness and connector terminals, but found no obvious faults. Key on, engine off, used the multi-meter to check for voltage and ground at the ignition control module and found both were present. Connected the lab scope to the ignition control module primary signal trigger input, started the engine and found the waveform revealed no faults with the primary trigger. This indicated the ignition control module was faulty.

Correction
Replaced the ignition control module and verified the vehicle operated properly. The customer's concern did not return.

Component Tests

Ignition Tests -> Carbureted/Fuel Injection

Tests

Koec Test

KOEC test is best used for diagnosing no start, no spark condition.

Connect test leads at ignition coil:
Yellow=coil(-)
Black=known good ground.

KOEO, primary ignition voltage must be present to continue with test.

Crank Engine and check for ICM switching at ignition coil while cranking.

As ICM switches, primary voltage spikes can be seen.

Resistance Test

Secondary ignition wire resistance
Connect ohmmeter
Red=either end of plug wire
Blue=other end of plug wire

Read amount of resistance:

10k ohms per foot or

25k ohms total resistance per wire.

Ignition Tests -> Fuel Injection

Location

Type: conventional
Best test Location:
Distributor, coil, and igniter terminals.

Component Location:
Distributor: at rear of CYL head.
Coil and igniter: at left rear of Engine compartment near brake booster.

CYL #1 Location:

(front of vehicle) firing order 1-3-4-2distributor rotates counter-clockwise

Ignition Tests -> Fuel Injection/Carbureted

Operation

System is conventional ignition using one ignition coil to produce high voltage for all cylinders.

Primary windings create a magnetic field that when collapsed across secondary windings, create high voltage.

This high voltage is required to overcome the greatest KV requirement in the secondary (normally the spark plug gap) this high voltage is transmitted from the coil to the spark plugs through a coil wire, dist cap, rotor and spark plug wires.

Tests

Secondary Ignition Test

Component Test Meter can be used to view secondary ignition waveforms.

CH1=Yellow secondary coil adapter.
GND=Black secondary coil adapter lead.
Black clip=known good ground.

Note: See LAB scope plug-in manual for proper hook up information.

Sweep , scale and delay may need to be adjusted depending on engine RPM and firing voltage.

Current Ramp Test

Ignition coil current can be checked using Component Test Meter & a low amp current Probe.

Connect current Probe to Component Test Meter as shown.

Perform auto zero adjustment before any measurements. This adjustment should be done prior to clamping Probe around any wire.

Press the auto zero button to zero Probe.

Clamp current Probe around the b+ side or the Control side of ignition coil. Do not clamp around both.

If coil is difficult to access, it may be possible to check coil current at the fuse box, if applicable.

Verify that Probe jaws are fully closed. If a negative waveform appears,open jaws & clamp Probe in other direction.

Ignition coil waveform should have a gradual rise or ramp as current begins to flow.

If vehicle is DIS equipped, current flow through each coil should be about the same.

If not, suspect resistance in power supply or ground circuits,or possible aftermarket assy not matched with OEM units.

If coil waveform has a sharp rise at the begining of the ramp upward, suspect shorted coil windings.

i have sure track a data base you type code symptoms etc in and this is what came up i know the ignition control module tested good on there machine but thats what came up on sure track.

Please let us know

This is a different expert. I was going to continue the troubleshooting in case the sensor did not fix it.

The first thing we need to do is run a few more tests to get the entire picture and see if any other systems have issues.
This is a series of tests that is used on all crank, no starts to isolate what is going on. You may have already done some of it but complete the parts that you haven't yet and we'll go from there.

Side note: That P0110 is for an IAT (intake air temp) sensor circuit. That can cause the engine to go very rich s you should get that resolved.

All "crank, no start" conditions are approached in the same way. Every engine requires certain functions to be able to run. Some of these functions rely on specific components to work and some components are part of more than one function so it is important to see the whole picture to be able to conclude anything about what may have failed. Also, these functions can ONLY be tested during the failure. Any other time and they will simply test good because the problem isn't present at the moment.
If you approach this in any other way, you are merely guessing and that only serves to replace unnecessary parts and wastes money.

Every engine requires spark, fuel and compression to run. That's what we have to look for.

These are the basics that need to be tested and will give us the info required to isolate a cause.

1) Test for spark at the plug end of the wire using a spark tester. If none found, check for power supply on the + terminal of the coil with the key on.

2) Test for injector pulse using a small bulb called a noid light. If none found, check for power supply at one side of the injector with the key on.

3) Use a fuel pressure gauge to test for correct fuel pressure, also noticing if the pressure holds when key is shut off.

4) Do a complete compression test on all cylinders

Once you have determined which of these functions has dropped out,
you will know which system is having the problem.

OK, what you have proven is that you are lacking pulse for both ignition and injector. That is determined by the reference signal supplied by the Crank sensor. That is where I would concentrate. It can be the sensor or any related wiring or even the ECM.

Here is a quick test for the sensor.

CRANKSHAFT POSITION SENSOR INSPECTION

NOTICE: "Cold" and "Hot" in the following sentences express the temperature of the sensor itself.
"Cold" is from -10°C (14°F) to 50 °C (122°F).
"Hot" is from 50°C (122°F) to 100°C (212 °F).

DISCONNECT CRANKSHAFT POSITION SENSOR CONNECTOR FROM GENERATOR DRIVE BELT ADJUSTING BAR
INSPECT CRANKSHAFT POSITION SENSOR RESISTANCE


Using an ohmmeter, measure the resistance between terminals.

Resistance:

Cold: 985 - 1,600 Ohms
Hot: 1,265 - 1,890 Ohms
If the resistance is not as specified, replace the crankshaft position sensor.

RECONNECT CRANKSHAFT POSITION SENSOR CONNECTOR

Check out the wiring diagrams in this post a few answers up

Use a scan tool and see if you have an RPM signal when cranking.

Yes, anything that will give you an RPM reading.

Using freeze frame is not a good way to do that. You need a live reading you can watch while cranking to be sure. If you do confirm a tach signal, I think I would try another distributor.

Even a lot of the cheap ones will do that.
