Hello
The situation looks like this:
The car ran/burned without any problems until the CR pump was removed. After sealing the pump and assembly, the car could not start from the shot.
Maybe I bled the system a bit poorly and additionally flooded the injection plugs with contact cleaner.
I tired the car a bit and it started, but it was literally 1.5 minutes, then it started to lose speed and the ENGINE STOP.
From that moment it did not want to start, and when it started with grace, it was for 3 seconds and again ENGINE STOP.
Errors from diagnostics are DF052, and over time DF891 and DF892. After realizing the situation, I disconnected the plugs from the injectors and dried the plugs, but the problem persisted.
The diagnosis was: injectors to be replaced. I even replaced the ECU along the way.
After replacing the injections with the tested ones, the situation is the same: df 052 and sometimes + df891 and df 892. And when the car starts, it takes 3 seconds and ENGINE STOP.
Along the way, I also replaced the CR pump (different fuel valve). The same all the time. The car was under a cloud.
With the arrival of positive temperatures and the sun, the car started to fire from the shot, but still for unspecified working times. From a few seconds to continuous work until gassing up (but it also varies).
Until the moment when, as if nothing had happened, the car started and even drove, the df052 errors no longer interfered with MOTOR STOP, and over time they even disappeared in favor of DF025.
After putting it in the garage, undressing the bundles, detecting one burnt candle that shorted the engine, the car worked as if nothing had happened. Error DF025 only appeared, but stopped as (99%) I pulled out and put in a 60 A relay from the candles heating the coolant. Since then, 0 errors, the car works fine.
Today in the morning (temperature around 0 degrees in the garage) the car fired up and again ENGINE STOP and DF052, but restarting it no longer caused him problems.
What else can cause erroneous indications "short circuit to injection ground or discontinuity of the injector circuit"?
- I cleaned the flowmeters yesterday - so today it should not pop up once again ENGINE STOP
- I checked the spark plugs on the battery for a short time and they were all hot
- the regulator from the candles does not show an error, so I assume that despite the short circuit on the candle, it works normally.
The problems noted are +15 V charging, the regulator was replaced last year, in December there was a strange symptom in the form of randomly flashing no charging depending on driving under potholes or tilt, and as if the 60 A relay hung up once from switching on two heating candles liquid, but after removing it and inserting it on the test it was already ticking.
Anyone share any suggestions?
