Do you smell gas at the exhaust during the no-start situation? I believe (and may be incorrect) but if it were to lack a cam & crank signal it may not open the injectors. There are folks here whom can give a definitive yes/no as to this.

Have we ruled out the fuel pump relay yet by bypassing it? When was the fuel filter last replaced? I know mine was original and I believe it was collapsing on itself and restricting flow.

If you happen to have or know someone with VIDA, these cars give additional information that you may find helpful that is beyond that of OBDII. Certain professional-style code scanners may also be able to display the data of the cam position and crankshaft position as sensed by ECU.
Wisdom requires knowledge as a prerequisite, but knowledge can be developed due to a lack of wisdom.
In order to learn how to fix something, you must first learn how to break it.

Fuel filter is new BOSCH fuel filter. Fuel pump is NEW BOSH fuel pump. Relay is NEW as well. at this point 3 reputable shops have looked at it and they all seem to think its due to the timing. The car has 76k miles and is the original belt and am getting poo14 even with a new vvt solenoid. So i think at this point i am about to bite the bullet and let someone do the timing belt and water pump on this car and see where it goes if that does not fix the problem i might sell it. I have come to find out that the evaporator needs to be replaced as well. The cars black with leather interior and i live in the south. That is not a job i am willing to take on. We will see what happens after i have the timing belt replaced.

Having just come in from the cold and wet doing this on a 99, if the shop,lines up the marks after preloading the VVT, it will code P0014

Vida says the exhaust hub needs to be set one tooth retarded to get timing right and I found this to be exactly the case

Hello
Is starter on this model located near a harness or crank sensor cable? If yes remove starter and dissemble and clean out brush dust and relube, if brushes have length remains starter will be good. Again if this starter is near signal cables as the brushes degrade the starter takes more power and creates an electrical field that disrupts the low voltage signals particular on the crank sensor and ECM can’t seem to time timing and fireing sequence. If your starter even acted strange while trying to start even better to clean it out. Good videos on you tube. On my S80 the starter is easier to R&R and clean out than doing oil change. I did this and my car runs great now. If I may ask if you do this could you try and measure the amperage prior to and after to see what change in amperage you obtain.
Keep us posted good luck

Check valve SHOULD be good but is it? I am wondering if the cam sensor code is a separate problem. Unlikely but possible. At any rate I would get a throwaway tire gauge and check fuel pressure at the rail. One of my 850's had a bad FPR and the only symptom was difficult starts, the problem went on for almost a year until I swapped the FPR. Or did the shops already check fuel pressure (at least one of them)?
