Does it have fuel pressure or does it actually have fuel in the engine? In other words, are you sure the fuel injectors are working? If not, check the fuel injector fuse/s. If it does have gas, remove a spark plug and smell if it's gas fouled. Then see if the engine will start up for a few seconds with starting fluid.
remove a spark plug and smell if it's gas fouled
Ok, first of all the engine isn't going to start even with starting fluid if the spark plugs are gas soaked. Clean them with some carb cleaner or replace them and try again.
Why did you clean just 3? You have to clean them all.
How exactly are you confirming that there is spark?
Ok, so you have spark. I assume it's a bright spark also. You are going to have to clean all of the spark plugs at the same time. A v6 engine will not run on only 3 cylinders and surely won't start on only 3.
Ok, so after you get the spark plugs cleaned and get the engine to start, you will have to find out why they gas fouled or if they just gas fouled from trying to start after something else went wrong that caused the engine to stall.
I suggest then you retrieve any codes from the computer module and check the fuel system pressure and replace the fuel filter.
Was the fuel pump and filter replaced after the engine stalled and would not start? Were the codes ever cleared?
What is the fuel pump psi?
It should be 47-51 PSI with key on. I don't know why though you have such a large difference between key on run and key on start.
Anyhow, I was looking for actually too much fuel pressure that could have contributed to the gas fouling of the spark plugs.
Speaking of the spark plugs, have you or are you going to clean them all and see if it starts?
Yes as in you did or you are? If did, does it start now, if are, let me know if it does or doesn't start afterward.
I don't understand what you just said.
You are getting ready for what parts?
You never finished your thought when you said, "seems if back plugs not fouled but front is fouled with gas". You have to use commas, periods (pronunciation) or I won't understand what you mean.
Are the back spark plugs not fouled?
Ok you might want to check and make sure you have voltage to each fuel injector with the key on run. I see that they all are fed from the same fuse but 1,3, 5 and 2,4,6 are fed from different branch circuits. The splice S114 is where the each branch off. Here is the wiring diagram,
If they both do have power, check the ground pulses at least one on each bank with a noid light.
Noid light while cranking of course.
Well, now you have to start thinking about the timing belt. How does the engine crank over? Any faster than normal, like it lost compression?
If the answer is yes, here are the instructions for removing the timing belt cover and the belt,
I would continue and take a look at the marks.
Was it the timing belt? I was thinking about this and wondered if that camshaft on the side with the wet spark plugs was even turning. If you haven't already removed the timing belt cover, perhaps removing that valve cover and see if the camshaft moves or not when cranking the engine over. If not, and the belt looked ok when you saw it maybe a keyway or something broke on that camshaft sprocket.
