Hi all, this post is mildy embarrassing. Hopefully my process and eventual result will help someone in future. My Accord has been laid up for 6 months with a snapped injector bolt that the mobile guy who came up on google didn't want to touch , turned out I should have just called a local engineering company. Not what you know it's who you know sometimes!
Now, having had to also replace the #4 injector , cleaned and refitted all injectors with new washers ect, the car is very unhappy. Smokes so badly I can't hope to take it for MOT. ( Which ran out on the 10th )
My HDS clone won't connect to the laptop via serial adaptor so I'm stuck with borrowing a snap-on solus legend.
It fails to run imrc and fuel rail pressure tests so I'm unable to get accurate results there, but requested matches the results in live data. ( It says the engine speed is out of range at idle - 819-824 is the idle revs range ) injector tests ect as follows
Original 3 plus #4 replaced with the original one that had previously been replaced for being a little out of range.
Fuel quantity which ECU adjusts No.1 Cylinder:-1.7 mg
No.2 Cylinder:-0.3 mg
No.3 Cylinder:-0.9 mg
No.4 Cylinder: 2.9 mg Elapsed Time:25s
Next is live data , as I didn't take a photo of the first test with new injectors for some reasons - this is all four injectors replaced with ones from a scrap civic.
Injector 1 correction Quantity(mg)
-1.4
Injector 2 correction Quantity(mg)
-0.9
Injector 3 correction Quantity(mg)
-0.5
Injector 4 correction Quantity(mg)
2.9
A trend begins with the #4 injector.
Running daig tests meant getting the engine up to temperature. This left a huge soot mark on the ground.
Turbo boost test first result was - Injector quantity out of range turn off all electrical devices.
Second was actuator normal.
Next injector test -
Fuel quantity which ECU adjusts No.1 Cylinder:-0.4 mg
No.2 Cylinder:-0.3 mg
No.3 Cylinder:-0.2 mg
No.4 Cylinder: 1.0 mg
Elapsed Time: 6s
A big improvement here. As I had ordered the new injector the moment that I fitted the old one previously and the car wasn't happy, getting ones from a scrap car for testing was a plus , although I know using scrap injectors isn't exactly the best idea!
I'm going to replace #4 today with a known good one. If the postie turns up anyway!
My 3 intact injectors from prior to sitting should be fine but mine were needing a clean as first run they weren't seating well and got filthy . Cleaned the injector seat, new copper washers, didn't change the smoke sadly, but the injectors seem to be seated well at least.
On thr driving side, there was an intermittent misfire - once warm intermittently rough running for a while. I discovered I'd put the vacuum lines for the egr on the wrong way round when putting the solenoid back in place. Switching them back around appears to have rectified the misfiring.
The car idles well other than a constant slight smoke and smell of fuel. Any amount of revs causes large cloud of black smoke. In motion the car is a little sluggish but not to the level of a boost leak or such. Boost comes on fine. No apparent issues there beyond the severe smoke. There are no stored codes and the eml light is not illuminated, the car isn't going into limp mode.
Checked air filter - needs replacing but it's not bad enough to cause issues.
Checked the imrc , no excess of oil sitting in the bottom.
I should get a HDS on it on Monday if I still can't get mine working but I'm feeling like something else is the issue here. The car was laid up from approximately the start of August. Over half a tank of Costco premium diesel in it.
Driving me up the wall - I've got till the 29th to fix it as I've surgery then which will leave me even more reliant on a car than now. Any suggestions would be much appreciated.
I'm ***uming that one injector is leaking - but which one is the question. I'll continue pottering away at figuring it out in the meantime. Every day is a school day , theres always more to learn, hopefully I'm missing something stupid
Update:
Refurbished injector came. Results of testing as follows
Fuel quantity which ECU adjusts
No.1 Cylinder:-0.3 mg
No.2 Cylinder:-0.8 mg
No.3 Cylinder: 0.5 mg
No. 4 Cylinder:0.5 mg
Elapsed Time:25s
Nicer results but it's currently still smoking!
