fuel in intake manifold

fuel in intake manifold
Engine B21E.
After disassembled, cleaned and reassembled everything, did not take well the minimum and even accelerating, it was not regular. Continuing to try, in the end you are no longer starting.
I again removed everything and I found this situation:
Petrol under the plate, until the air inlet tube
still gasoline in the intake manifold. Here you can also see the attack of the 5th injector
Where you can get all this gas? Keep in mind that since you are no longer set in motion, I have tried several times to get it started (fifty). The starter turns the engine dancing all over but will not start.

leaky cold start injector/valve, leaky main injectors. excess fuel pressure from bad pressure regulator (I think Volvo K-Jet had one, but I dunno, I never owned one)
I think I'd pull all injectors, and bring them to a diesel injector shop, have them do a 'pop test', and check the spray patterns, replace any that are out of spec. ALWAYS replace the injector seals before reinstalling them...
wait, B21E ? I've only ever heard of B21F engines in US model 240's, which were all fuel injection. B21E was probably a european/world market variant, and if so is that a carberuter? then ignore all what I said above, your carb likely needs a full rebuild and may well be worn out with age.

Hello, six months ago I had to clean the injectors, the nozzle holders and all O-rings.
Spark plugs, wires, cap and rotor are new. After disassembled, cleaned and then remounted, the engine has started and it seemed to work. One day he stopped.
The engine is B21E 1986 cc for the European market (I am in Rome). No carburetor.
Thanks for the answer

okk, so if its CI/CIS, we're back to the leaky cold start valve, and/or leaky injectors. to determine if the main injectors are bad, they should be removed and taken to somewhere that can do a 'pop test' where they pressurize them and measure the pressure at which they start spraying, and also note the spray pattern. here in the US, there are diesel injection shops, that normally work on big trucks, which are equipped to do this.
cleaning usually won't fix bad injectors, they need to be replaced.
