Owner of a Mazda 3 2006 1.6 diesel(HDI engine)

First time doing this, decided recently to take off intake manifold because ive heard those get clogged easily, noticed the car was losing power

Took it off, saw a severely clogged intake and cleaned in to the best of my ability  
The intake ports were also clogged, however i rushed and impulsevely took a screwdriver and cleaned it spotless… thats when i realised that it may have clogged the port… tried to get as much of it out and prayed to jesus it would start after assembly but nothing, tried giving it gas nothing, floored it nothing, it just cranks but no start…

I checked multiple times if i may have forgotten to plug something in, everything is in place as it was  
Is there a way to get the gunk out of the intake port? I am positive it is because the ports are clogged or the worst is yet to come?

Probably going to have to put it in a dip tank with solvent.

I am sorry, put what in the solvent?  
The intake manifold is clean…  
It is the holes below it that i believe may be clogged  
Is there a way to get it out without removing the head?

Appears more cleaning is required. But since the engine started and ran before the intake manifold work (albeit w/reduced power) , for cranks, no start in a diesel, common reasons:

- no fuel
- no compression
- glow plug fault

Are there any obd II codes?

Have you verified this conclusively by attempting to hook up your scanner on someone else’s car?

Oh no! All of that carbon that fell into the ports got sucked into the cylinders when you tried to start it so there’s nothing left to remove in the ports. The cylinder head is going to need to come off I’m afraid.

I wonder if removing the spark plugs and cranking the engine a few times might help expel anything that fell into the cylinders during the cleaning process? Years ago I had a VW Rabbit that cranked ok but wouldn’t start after doing a fuel system pressure test. Turned out the test had put too much fuel in the cylinders. Plug tips were wet w/fuel.

Oh, forgot about that. Good point.

The issue is fixed, cleaned the engine head at the mechanic and the car now runs fine, however the turbo issue is getting worse it seems, used to be p0299 low boost now im getting p0045 and p0238 codes, could it be the boost pressure sensor?
