OK, good. The spark plugs threw me for a minute back there.

So can we can describe the problem as:

Engine starts OK, runs if given more throttle but dies at idle.

HAD air bubbles in the IP fuel feed hose but no more air bubbles, just full of liquid.

Is that correct?

One day it just happened, not related to any immediately previous adjustment or other change?

Anything else? Does it smoke? Idles rough but if you give it more fuel does it smooth out?

Yes there is no more air bubbles and wthen throttle works with a lot of vibrations. There wasn'any ajustment i was driving parked and a few hours later it was bad. The engine smokes in black since a lot of time. I dont know d24tic that doesnt smoke but it was working good pretty good.

Starting to sound like slipped timing, or MAYBE a stuck injector.

Are you able to keep it running long enough to figure out if it is just skipping on one cylinder, or if it's running poorly on all of them?

A video of what it's doing might help us a lot in understanding the symptoms you're dealing with, if you have the ability to take one and show it to us.

I'd verify free fuel flow from the tank through the filter, then try with an electric lift pump.

Yeah, that still is sounding like severe fuel restriction and/or aerated fuel.

As noted above, using a low-pressure electric lift pump can identify whether it's an issue with air ingress on the supply side, as long as there's not a restriction or air leak upstream of the filter. If you put in a pump, best to put it in line BEFORE the filter, not after, since otherwise if there's still a leak at the filter head you could continue having problems.

If you can't get hold of an electric pump, a manual primer bulb and an external fuel can elevated above the height of the IP can do the job as well, you can run it off that and see if the symptoms change.

I had one once where an injector stuck open and was letting compression get pushed through back into the IP, filling it with air, and did some similar things. Confirm there are no problems in the IP's fuel supply before exploring this though.

Did you refill the fuel tank shortly before this started happening?

Where are you located?

[rado561]

yes that happened after i filled it up. I am from Europe Bulgaria. Here there is Euro standard but the fuel is terrible even in gas stations like shell.
Thats why i think its possible to be stucked injector.

Water in fuel? Does your fuel filter have a drain valve on the bottom? Can you drain some fuel from the bottom of the fuel filter into a clear jar to check for water?

Hi everyone again. Thanks a lot for suggestions. I finallu found an electric pump i connected it before the filter but it doesn't work again.I think that the last option is stucked injector.I dont know what else it could be.
