1997 Vt Commodore issue

[Weglee]

Hi sorry in advance as this will be a long one and I could not find one that exactly fits my issues.
Not sure when this started but has been an issue for awhile.
I have a 1997 series 1 Vt Commodore which has a few modes but had been running like a dream for ages untill one day i had stop to do something and when i got back in it would start but was idling like a bag of **** and when you put your went to rev it it sounded like it was not getting enough fuel (gurgling). I turned it off and pop the bonnet dumb founded so closed the bonnet went back inside for about an hour came back and it started perfect, so I drove it home and drove perfectly. Didn't drive it for a few days then next time it happened while I was driving so pulled over and rang for a tow truck and bought it home.

Did some research and checked for codes by bridging the with wire and the only code that came up was 12, and as of yesterday I have changed and in this order
Crank Angle sensor
Fuel Filter
Fuel Pump
Plugs and lead
Changed back to old coils and clean plate (was a suggestion from neighbour )
Check throttle body which looked ok
MAF looked ok
New o2 Sensors
New coolant temp sensor
had done oil and filter only about a month before
checked for air leaks.

Before doing the O2 sensor and the coolant sensor (while waiting for the deliver) it started and idled perfect so I took it for a quick drive down my street which is a culdesac as I was turning right it started running lie it was starving for fuel again so parked it and waited for the delivery ( yes ebay on a budget)

So I changed O2 sensors and the coolant temp sensor, started it and sounded perfect put it into drive and same as before running like **** same as before.

So I am very frustrated as I don't know what else to do.
So please help if you can (I am a female trying to do this as don't have any one to help so be nice hahahahah).

And I just notice there was coolant coming out of a bold in the head while I was idling (pic attached)

Gee why can't my wife be more like you?. Seriously though, when a engine isn't getting enough fuel you tend to get backfires which you didn't mention. It could be injectors, about the only thing you haven't changed already. Hopefully the "brains trust" will be on soon to shed some more light on your problem.

Looks like you maybe getting water in the combustion chamber. Possible intake manifold gasket or something similar. Not sure about V6's.

firing the parts cannon is not diagnosis
when you pulled the spark plugs, how did they look, wet, coroded, all the same
when you changed the fuel pump, did you fit quality or ebay
what were the plug connector to fuel pump condition like
have you changed/tested the fuel pump fuse and relay
have you drained and cleaned the fuel tank
do you use cheap fuel or busy main brand fuel

May just be my old eyes but it looks like there's a loose bolt to the left of the injector above the coolant weep?

As i said in the info yes it is leaking I have checked it and it is not loose. I have tried to tighten it but did not want to go to far with it.

No it does not backfire and yes injectors was my next thought but not fun trying to change them.

Ok i thought that would help if you new what i had done firstly.
Spark plugs pics added they are not in order from when i got them out sorry. All different and some were a bit wet. They were autolight again from ebay. I could pull out the new ones and have a look but car has not had much action yet so not sure if it is worth doing.
Fuel pump ebay
Not sure what he plug connectors looked like did not think to check
Have changed both relay and fuse (could test the new ones but not sure how to do that)
I drained most of the fuel out of the tank and had a look inside and looked ok
Fuel i use is mostly 95-98 never used e10
Thought was to drop the tank again but i have over half a tank of fuel and i was told you were not able to syphon out the fuel.

those plugs are filthy, how many km on this motor, is it an oil burner
have a good look at wiring to DFI,
and fit the original parts back if bought from ebay

yes thats why i replaced them, 256,000 and no it doesnt burn oil it has a small oil leak
have check wiring all looks good
so you mean every thing i got from ebay put the original ones back on the car why it was playing up before I replaced them with the ebay stuff.
