Fiat Bravo won't start after self learning reset

[Seistar]

Hi dear experienced users...

I bought a Fiat Bravo 1.6 jtdm HP in November, DPF clogged and engine light on the dashboard. I took out the DPF for a perfect cleaning, and erased the error message of the DPF with a basic OBD tool.
Then a EGR error came out, so I took it out for a cleaning and i did the butterfly valve clean at the same time, both were dirty but not that much...
Then i realised I would need to reset some parameters, so i bought the complete version (5.3.0.1) of Multiecuscan.
I re installed my clean EGR and butterfly, the car was starting OK, but still got random error messages and check engine light coming on dashboard.
I took out the car of the garage (first mistake) and i did a EGR reset, but no change. Error came out "EGR is blocked".
Instead trying a new EGR, I tought it might be a smart idea to do a full self learning reset (second mistake I guess). Now the car sits outside and refuse to start again

EGR error keeps on coming back, I ran a butterfly test and it moves freely. No other error.
So , where did I f** up, and how to get it back to start? I'll buy a new EGR, but I doubt a faulty one leads to a no start...

Thanks for your help!

Anybody out there...?

Can you try to power the starter motor when ignition is on? Jump it with a wire, or push start the car?

Thanks for the answer.

The starter motor revs when I turn the key, the engine seems to be nearly starting but doesn't.
I opened the butterfly to see if it's opened, and it's working fine.
Just noticed a bit if smoke coming out when I tried starting, like a wrong crankshaft position (not sure if my English is good enough to explain).
Didn't try to shortcut the starter motor, but I would give a try to push-start. The car is a bit uphill, if it works it's fine, if not.....

Hmmm ok, did not know that the starter was engaged.

Tried checking the timing? Seems odd but it is a starting point. Also the timing in between cams (gears on cams, gearbox side of engine)

I just wonder what in the self learning reset can cause this...
For sure it's not mechanical, it's all coming from that reset.
The engine always started as it should, even with the DPF or EGR issues.
I was thinking I did something wrong in the resetting procedure.
But I can't understand what. It sounds like the engine doesn't receive the diesel fuel, or not enough, or not when it should. And the electric pump in the tank works fine...

Is it possible that the reset gave a wrong crankshaft position sensor value?

When this kind of problem occurs, the first step is to check the basics.

It happenned during the reset, but it can be something else.

Are the injectors codes present in the engine ECU? (the unique code each injector has)

And you seem something odd in the engine parameters? Especially at the Engine ECU if says: PROGRAMMED
And at the Engine Startup: Allowed.

Thanks a lot for your answer. You're right, let's focus on the basics, and step by step.

The injectors codes are OK. Engine Programmed and startup allowed. See attached pics if you see sometings odd by your side.
For me not much, except the blocked EGR error and Flow shutter valve test Failing to execute (not even sure there are swirls on the engine though).
I'm not a diesel specialist, and more confident with bikes or carbs engines, but it sounds like the engine starts a few seconds, maybe 4 sec. Hardly iddling, if I give gas it's worst, and it stops after some seconds. Now I have the feeling the engins chokes, probably not missing fuel, but air...

I have received a new EGR valve, will change it and see ...

Thanks for your precious help!

Hmmm if it is an air measuring problem, you can disconnect the MAF sensor. (round tube with sensor directly after air filter) The car will go in a sort of worst case MAF senario, it will start and run but will throw an engine code.

An stuck EGR can cause a crank no start!! Have read lots of wierd stories with an stuck EGR.

Maybe the car knew the valve was stuck open and adapted to it. When resetting the car "forgot" that the valve was stuck open and no longer runs. Think this is the thing you need to check first.

Great
It feels like the beginning of a solution, let's check this.
