We almost have it! It starts and runs but real rough engine I started to take around the block but thought it may die
After fuse box preventive fix will not start

And engine light is on
Glad to hear, what did you find?
How long did it run? Might be somewhat flooded. I dont know for sure in this situation, but sometimes cycling key on and off may pulse some injectors. Therefore when it finally fired some cylinders may be flooded.
How about a recheck on fuses for s#### and giggles.
Do you have access to code reader?
If only the fuses i mentioned earlier that make sense still have no power.
Disconnect battery, get a good night sleep knowing its running and we will get you the rest of the way.
Then tomorrow reconect battery and retry. Fuel will have evaporated and trouble codes may have cleared overnight. Might still be slighty rough as plugs clean up. Shouldn't take too long.
EDIT while battery cable is off go ahead and remove both cables and then touch the cable ends together gor a few minutes. The Computers may be confused due to previous issues. This procedure wipes out anything stored in their RAM, random access memory. This is their "learned" operating conditions, and if it is incorrect it can cause all kinds of weird stuff and they have trouble figuring out whats right and whats wrong.
Best to let them start learning all over again with problem corrected.

I think you are right it is maybe flooded. I did not run it too Long. Why disconnect battery ? For my knowledge
I don’t have a code reader. And THANK YOU!
Disconnecting both the positive and negative cables and holding them together allows the system to fully dissipate any residual charge and allows the computers to reset. It is important to firmly connect the battery cables to the battery and not allow them to spark on and off as the contact becomes connected and disconnected. In an unlucky situation, the sparking can be interpreted by the computers as a signal and lock them up.
Disconnect to clear codes and any "learned" operating strategies.
It sometimes takes longer to relearn after a repair than learn from base programming. Plus base programming may be closer to running in an acceptable condition, than slowly relearning from unacceptable conditions when try to compensate for something thats been repaired.
Bad old habits don't die easily?
I checked my chart again today - the chart is correct!!!!!!
Fuses 29,31,33 shown in above diagram ARE IN THE REAR FUSE BOX!!!!!
So I rechecked the fuses he showed as dead against my chart. I changed the font to red for al fuses he listed as not having any power.
It made even more sense that fuse 41 was the culprit - now if he had checked rear fuse box ALSO he would have found these fuses dead as well
So when you look at the red type on the attached chart
fuses 2 and 4 requires high beam on,
fuses 3 and 5 require low beams on
fuse 10 and 15 require either stop lights or right or left turn signal
fuse 20 key has to be turned to crank (start)
fuse 25 -- I question if this fuse is even found on other 6 speed models - my wiring shows its only used on auto equipped
fuses 19, 21, 23, 26, 31 and 32 are all fed from fuse ignition switch circuit C which is fed from fuse #41
fuses 28, 29, 33, 35 and 36 are highlighted a different color on my chart because all of these will be "dead" when there is a fuse box broken wire issue, faulty relay #42 or other issue.
In this case it was "other issue" relay 42 is energized by the ECM in the ignition run or start position. The ECM determines if ignition is in run or start from fuse #31 - AND fuse #31 was not sending that signal to the ECM because t is on the list from the ignition circuit C fuses!
In conclusion - I WILL NOT be posting new charts because the the fault was not with the chart but rather with the person using it.
After a day with the battery off then reconnection it starts and runs but very rough still. I took it for a light 10 minute out and brought it back. I guess I need an engine light code
That sounds more reasonable.
I will bet it runs bad !!- seems like misfire on 4 out of 8 cylinders. This will also cause the P0300
Cylinders 2,4,6,8 are all of the cylinders on the passenger side.
First check fuse #29 Inj B 20 amp fuse. Key in on position use your test light as you did prior.
This fuse is power to all four injectors and ignition coils see diagram
If power on both sides of fuse, unplug one of the injectors on that side of engine - and now with key on check for power on the pink wire of that injector.
If no power on either side of fuse problem maybe inside fuse box - I know injector A fuse has power or it wouldn't run. It appears from diagram they are fed off same bus bar.
If power on one side - fuse is blown - replace and retest - if it doesn't blow then start engine and see if it runs better.
Let me know how it turn out., I can provide further assistance if needed - might be tomorrow
EDIT - Also be sure fuse fits snug in fuse box -- if no power on either side or power on both sides of fuse but not at injector.
maybe push fuse towards one side while it running to see if it smooths out. (long edge of fuse towards or away from relays)

YEA, YEA !!!!!!!!!!
Great job - you almost follow instructions well.
I say that with some kidding, because I believe in post #23 last night I mentioned
How about a recheck on fuses for s#### and giggles.
ITS ALL GOOD!!!!
I hope this increased your confidence in electrical repair
AND some of those following the thread, I hope you were able to learn something as well.
HOPEFULLY weather is good where you are, so that you can get out and enjoy your smooth running Blur, tonight or tomorrow.
I think I will go have a cold one 🖐 to celebrate. 🍺🍺🍺🍺🍺
GREAT JOB @NMSSR !!!!!

I think I do good then hindsight yes I miss things. I’m hopefully getting better and next time following instructions. Yes celebrate
