Repairing, restarting a problematic .... suv

 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



ECU (Computer box) briefing

 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.

Repairs are getting more expensive; it is easier to repair older engines but not the modern, electronically controlled ones

 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





Black smoke after replacing turbos and injector

 It could be due to the intercooler.   Signs of defective intercooler:   black soot and oil at the underside from the leak.
