The answer is not in the keys. It is in the pairing of the keys and the starter button. There are stories where cars dont want to start and mechanics have changed from all sensors to ocils and injectors. Only for the scanner to show that something is wrong with the key programming.
So the first step really is to think electronic. We need a sort of password or registration. First step, have your electronic engine scanned.
The initial fault was the electrical of fuel system, the car still wont start. Then they went to the second fault - the crankshaft sensor and the E.... engine finally started
This post has a very poor readership. While there are plenty of articles that may interest a handyman, the stat on viewership does not match the effort that went into the posting. There are only 49 views after sometime
Maybe this is not an interesting topic, or people would not invest time and effort for the repair. They would spend thousands in a repair shop rather than get their hands dirty or bang their heads thinking of how to know the parts, get the tools, and get the repair done
Learning to repair is:
1. Self improvement - we must improve everyday;
2. This increases your value - to your employer and community even your family. You save money in repairs.
3. This knowledge comes in handy if your are travelling to far away places and no mechanic is around. You will be thankful that you did
Some would say that mechanics repair using any of the methods:
1. Trial and error (guesswork) the mechanics does have a theory and hypothesis on what could go wrong and tries, and tries if one does nto work
2. Luck - he may have tried something and the car suddenly lights up;
3. Sorcery - he prays to the God, prays before deities that he may have the correct repair
4. Scientific critical thinking:
1. Use of scanner to diagnose what is wrong so that he can easily find the faults;
2. Differential diagnosis:
1. Comparing this with similar malfunction;
2. After cleaning: compare the good part and bad part.
We see this often:
1, No spark - trace when there is no spark: at the spark plag, or the wire if not by process
of elimination the source is the coil
2. Fallo (misfire) can be from:
1. From electricity - coil or 2 gas: from the injectors
If from coil, remove the coils one by one. If there is no change in engine operation if a coil
is removed, then that coil is suspect
If from injector, remove the injectors and fuel rail and see how the tip works. If one does
not spray,it is candidate for cleaning and or replacement
This involves comparison (diagnosis) of the normal and suspect part. Remove the suspect part and borrow a regular working part. If it works, the suspect part is now candidate for repair and/or replacement. (This is the KT approach: what is, what is not)
So that we may know something if the car does not run; ECU may have something to do with this ECU controls the car. It is the brain of the engine.
After several trips to various p up service center nearly 6 digits in repair costs (labor and changing sensor) today our agony with the pick up truck which is nearly new, is over. The trouble was with stuck and dirty turbo actuator (the variable turbo actuator is prone to problems)
The expense this time was lower: cost of scanning and the teardown and cleaning.
A grab businessman who used to be HE operator, worker in car manufacturer, and head mechanics of car rental company said that most of car mechanics of service centers up sell, or sometimes outright doing guess work for the repair: not methodical or critical thinker.
Today we spent only P800.00 for scanner and the rubo actuator cleaning We can use the pick up again. Before the brand was the go to brand: we bought two vans and one pick up from them, Now we are thinking hard whether we should stick to them.
One advice to avoid this turbo problem is to allow the cooldown of the engine for 5 to 10 minutes before turning this off. Otherwise you cook the oil which cools down the turbo shaft.
We see mechanics of Matz seeming to have incantation to restart an engine that has been paralyzed for a long time. And we can see Matt of Diesel Creek rejoicing and laughing at the top of his voice when he restarts an engine. It should be.
Matz even says it is hula2 (a guess) because he could be wrong. Matt of Diesel Creek gave up on a repair of gasoline operated forklift. I would give up on 90% of what Matt has restarted.
Thats 33 years old. The tracks were stuck and the only thing he said that was working was the engine
And for $500.00 for a running CAT engine, he said the amount was worth it. Yes he was able to make this run after checking the fuel, and making sure that fuel reaches the injector. And he was made able to unstuck the tracks. How amazing.!
Matt of Diesel Creek shows how simple and straightforward the repairs of mechanical engine Those that are all ready electronically controlled looks complicated and expensive to repair.
Most of the engines of Heavy Equipment repaired by Matt are diesel. The electric part only is about battery and starter. That is all. (The only complicated ones are bulldozers that have pony engine. First you have to start the pony engine and then the pony engine will start the main diesel engine) Then it is a straighforward checking and replacing oil, fuel, oil and fuel filter. That is it.
But there are two main paths to pursue in electonically controlled engine: fuel (which is also electonically controlled by ECU fuel injectors and sensors) EGR valve, crankshaft position sensor. And they are not cheap
Thus Matz had to resort palit (change) parts (no more repairs) that involve sensor, ECU (which cost 6 numbers) And a day repair by Matz can cost upwards from P5K to P100k. That is not my type of repair.
Our Navarra pick up repair tab runs up by 6 numbers too. Huhuhu
I have watched his video from FB.
I noticed this Visayan speaking mechanic from Oroquieta:
1. Most of defective vehicles are from Ford;
2. He speaks in Visiayan
3. He does this scientifically using a computer;
4. He sells both his parts and service (which sounds pricey) He changes modules rather than repair of individual parts.
He does excellent repair but it looks expensive. He has been expanding as many as far as Basilan and Zamboanga, and from Cebu goes to him for repairs
But his analytical skills are tops.
It could be due to the intercooler. Signs of defective intercooler: black soot and oil at the underside from the leak.
