Fuel pump testes directly to battery and works. Reinstalled it back.
And measure 3.5v at key position 2, 12v when cranking.
Guess fuel pump works atleast(or badly).

Gonna test realease fuelpipe before fuel regulator. See if it comes fuel there.
Gonna test if it comes fuel before and after fuel filter.

Have switch places with fuel relay.

[leebron]

* Fues relay clicks.
* No fuel at feederpipe at pressure regulator.
* pump works with seperate battery and sometime with the cars contact.
* pressure from pump seems good tested in water.

I think the fuel gets stuck in filter. It might be clogged.
Gonna replace with new filter today.
Just confused why it not always works with cars wired plug. (Maybe it works better now) time Will tell after switching fuel filter.

[leebron]

Have replaced fuel relay.
Have changed fuel filter.
Tried forcing pump on 12v from other battery.
I hear the pump working but i Get no fuel at feeder pipe to fuel pressure rail. ?
Wtf? Could the fuel pipe be that clogged after filter some where?

[tidla]

Generally the fuel pump will activate to pressurize the system, then it will look for a rpm signal from the crank sensor..

[martin42]

Have you tried removing the fuel pipe from the outlet side of the filter,fit some suitable size rubber tubing which can go into a bottle so you can see if there is any fuel flow at all when pump is primed?

[leebron]

The pump works in a bucket of water.
It works in the petroltank with key, but just to be sure its not som sensor blocking it i have connected it to an 12v external battery.
New filter. So that isnt blocking.
But i get no fuel at feedpipe to injektor rail.
I will now remove the new filter and try blowing air through the pipes to see if something is blocking the full fuel rail.

Looks like you are making good progress on this ... I'm interested to see what the problem turns out to be

[leebron]

Iam blowing with a smaller kompressor in feedpipe back through the car without filter in.
It comes out oil? Now iam seriously worried?
Can oil from engine get out to fuel rail?
Have to get me a new pump. It was working, but suddently it died...
Maybe the pump was the problem afterall.
Feels like beginning all over again when i saw oil.

Tried engine starter can sprayed in throttlebody. Car Didnt start with that either.

[leebron]

Not oil just really black carbon fuel. Guess previously owner hasnt replaced filter for along time.
I now get nice clear fuel at feed pipe at fuel Rail.
The car still dont start. Pump is working now.(didnt for awhile probably because clogged pipe somewhere.

So.
New relay
New filter
No clogged fuel pipe.
Working pump.
Spark at new plugs(tested all of them)
No error codes.

So next.
Dirty injectors?
Low pressure from pump or regulator? (Test tomorrow)
What pressure should it be? 2-3bar?
I feel like Engine almost want To start when i turn on/off key 3-4 Times before cranking To get more fuelpressure.

Could still be cranksensor. (But have no codes pointing)

[cd 2.2]

Could be camshaft position sensor I guess ... Injectors "could" be blocked if it's dragged a load of dirt through! Check the vacuum pipe to the fuel pressure regulator also, if it's damaged I guess that could cause issues with fuel pressure

From what I know of cam / crank sensor faults the engine will just turn and turn, maybe even backfire! Have you checked if the plugs are wet with fuel after a few turns of the engine? If they are this (in my opinion) is indicative of a sensor fault! Even if no fault code is presenting ! What I have learned recently, through this forum, is that the engine will try to fire at the wrong part of the cycle with a sensor fault. This in turn can cause a failure to start ... even backfiring in some cases!

Please correct me if I'm wrong! I must say I admire your perseverance in finding this fault 

[tunnie]

2.2 petrol will fire and start, even with cam sensor disconnected. Just take a lot of cranking. Can't see it being injectors, should give a code for one, or at least start and maybe miss on one if that is the case.

I still find it odd that there are no codes, there should be some. What code reader are you using?

[leebron]

Bought a cheap full pressure tester. (Stupid) it didnt match the fuel guage pressure test.
I thought what the hell i tried comnected it directly on feed pipe.
The pump gave high pressure and suddently died. (Stupid?) i might killed the fuel pump?
But then i tried crank the Engine without pump connected and it fired, the car Started!!! And then it ofcourse died without more fuel.
Could it been pressure regulator or bad pump?
I tried blowing/sucktion on fuel regulator. Dont know if that was solution.

Have to find me a new pump.
No i dont get any codes. (Opel obd2) something. I get live data and have get codes earlier at fault codes same as on garage. (So i do trust it)

[leebron]

Update. Really need advice now! Iam out of ideas.
Okay. New fuel pump Didnt make any diffrent.

I have fuel at sparkplugs they are wet when i pull them up.
Smell petrol. But why dont the car fire.

No codes.

Could it be timing belt?
By why would it that suddently be the issue? The car was fine all day and parked at house and suddently Didnt want to start.

Replaced.
*relay
*fuelpump
*filter fuel
*spark plugs

[05omegav6]

Failed fuel pressure regulator?

[leebron]

Failed fuel pressure regulator?

As in car gets to much fuel?
The sparkplugs are wet so it get fuel atleast.
Could pressure reg.. Really make the car not start?

I would love a code right now.

What makes cam sensor error so Often on 2.2.
It was replaced 4months ago at opel genuine garage.
I have 1 year warranty. But cant demand a new one as iam deffinitly not sure thats the fault.
