Hello,

 

Can someone give me the information in ohms of the engine coil (spark plugs)?

Check the pic in attach (engine coil)

 

For the Fuel Pump, I measured the resistance and it gave me a resistance of 0.16 / 0.13 ohms and I think the pump should have 0.27 / 0.25 ohms .. ?

Thank you

 

 

 

Hi dude,

 

Thank you for ur reply.

The values have to be between 8,4 kΩ / 9.1 kΩ right ? pins 2-4 and 3-4 ? or 4-1 and 2-3 ?

 

And for the Fuel Pump, I measured the resistance and it gave me a resistance of 0.16 / 0.13 ohms (or 0.13) and I think the pump should have 0.27 / 0.25 ohms .. ?

 

Thank you

come on its a brushed dc motor dont be so upset.

if it delivers pressure and doesnt blow fuses its absolutely fine

The image I posted is very clear.The output of the ignition transformer consists of 2 secondary coils. One between the outputs to spark plugs  for cylinders 1 and 4, and the other between the outputs to spark plugs  for cylinders 2 and 3. Each coil should have a resistance of 8.4 - 9.1 kOhms. The primary coils are not directly accessible to the ignition transformer connector but there is a window with a cover.Under it there are 3 prongs where you can measure the coils. The 2 coils should have 0.8 - 1 ohms each.

It is not relevant. What is the issue with the fuel pump?

Yes, I saw that.

I dont understand where is that location. I need to remove that plastic cover ? Where is the name Champion ?

 

Yes, the cylinder 1 - 4 = 8.89 Ohms and cylinder 2 - 3 = 8.96 Ohms all in scale 20k.

 

For Pins

Scale 20k Ohms

 

1 - 2 > 2.98

1 - 3 > 2.98

1 - 4 > 1.90

 

2 - 3 > 3.59

2 - 4 > 2.29

 

3 - 4 > 2.29

 

Scale 2k Ohms

 

1 - 2 > 1.335

1 - 3 > 1.330

1 - 4 > 0.500

 

2 - 3 > 1.544

2 - 4 > 0.591

 

3 - 4 > 0.592

I say this because sometimes I have difficulties to connect it in the morning, it seems that it takes a little longer than normal .. and it has already happened, he doesn't even call in the morning and the afternoon does. And sometimes it happens, for example in a semaphore he will  below and only around the 3rd attempt is that it turns on and sometimes almost dies, but it turns on .. 

 

For example if I accelerate with it with my hand (by the motor cable) and release it, when it goes back to 800 rpm it seems like it almost dies.

I'd normally expect to find that name on the spark plugs. But only if they were Champion brand spark plugs obviously.

 

Also I don't understand your obsession with resistance; most people are more concerned with voltage and wattage since that's what drives the circuits.

This Coil is Champion .

I think is the resistance is little bit low, i think i don't make a good explosion.

Because sometimes it takes a long time to turn on and sometimes the machine hasn’t started in the morning, or when it die (turn off), sometimes it turn on only the 3rd / 4th time.

 

I leave 2 example videos

 

Video 1 (you can see the very low rpms, when I walk very slowly, a little bit above 10k rpms)

 

Video 2 (try to feel the sound when I accelerate and release with the cable)

 

I dont think there is any issue with spark.
Throttle respnonse is good.
I say check for vaccum leaks clean throttle body and reset it with msm.
Also swap out a different crank sensor.
Are you sure plugs are gapped properly.
Remove the coil plug and insert 4 plugs touch them to the rocker cover and crank the engine.
Take a look at the spark to see if its strong or not

@Joob

The ignition transformer is good.

The issue you are describing (long cranking, stalling at idle) could happen from several reasons.

• low fuel pressure (clogged fuel filter, fuel pump is worn out). You need to measure the fuel pressure.
• faulty coolant temperature sensor
• dirty manifold pressure sensor

I'll do that

I had already made this exchange, it was one of the first things.

I happen to already have the gasoline filter to change, but I have not done it yet, but to see if I do soon. I checked the resistance and that gave 0.16 ohms and also 0.12/0.11 ohms .. I think very little, because I have been watching and I think it has to rise the 0.26 ohms. Right ?

I will have to measure the temperature sensor, but I see it works because the fan and temperature level works. but I also think it's strange thing is that the car has to scald immensely and only when the temperature goes to the 70º is that the fan turn on, that is, it goes up very little and it takes too long to rise.

I also cleaned the manifold pressure sensor and I verify the measurements, and it seemed okay.

The resistance measurement doesn't mean anything unless it is open circuit. Why do you keep asking about it? Did you read any reference material about those values? Also, what milliohmmeter are you using with such high precision?

It is more important to measure fuel pressure on the injectors ramp and how well it holds pressure.

Ready I already changed the gasoline filter and it was really black and with some residue.

Whoever had the car before sure that never changed the filter due to the difficulty it is to change on this Skoda Felicia -.-

 

For now it looks very good, anything whistle.

Thank you guys
