99 s80 (non turbo) can't start anymore
My s80 has 158K miles.
I had occasional engine stall on highway. So, I decided to replace fuel pump and fuel filter. Also replaced PCV box and cleaned the throttle body ...
Now I can't start my s80.
I can hear that fuel pump is running for couple seconds after I turn the key to position II, and engine cranks after that, but fuel pressure is very low (near 0 psi) even after several cranking attempts.
I checked the fuel pump relay and a fuse - they seems to be OK, there is no visible fuel leak also.
No trouble codes on OBDII scanner.
I have old battery, so tried to jump start with no success.
Can somebody help me to diagnose this problem? It drives me crazy :-(

Tech, you are the man :-) I recharged the battery, added 1 gallon of fuel and after 2-3 cranks my engine started.
I spent last 2 weeks looking everywhere, cleaned all the electrical contacts, cleaned a bunch of other stuff ...
I swear it was some fuel in the tank, but apparently not enough for new fuel filter and the pump.
OK, now I see some smoke from the tail pipe, but I ran engine only for about 5 minutes.
I cleaned the PCV system, so I expect no / less smoke. Will test it more ...
The main problem now is that engine sounds like my grandmother's sewing machine (not very loud, but quite noticeable, I did not have this before).
I suspect this is because I decided to tighten head bolts at some time during no-start troubleshooting, which is now I think was not a good idea.
Do I need to replace the head gasket and tighten it correctly now?
