Checked the fuel pressures. Still same as when I checked them ~1.5 months ago.
System pressure (fuel pump on, engine off) - 65psi (4.5 bar)
Cold control pressure - ~25psi (~1.8 bar)
Warm control pressure - 50psi (3.4 bar)
When I started the engine, it started at 1.8-2.0 bar and just slowly rose from there to 3.4 bar over the course of 30 - 60 seconds. Then just sat right at 3.4 bars from then on.
Engine still hesitates to start when cold... Had an embarrassing moment with a friend who saw the car for the first time after rebuild and wanted to hear it start... Took almost 10-15 seconds and pumping the gas to get it started... He just looked at me blankly and said it sounds like it needs more tweaking...
I just ordered a new O2 relay (they're inexpensive, so I figured worth a shot). Will also start checking TTV and CSV with ohmmeter.
Oh! and I also discovered when showing my friend the car that I forgot the gas cap at gas station when last refilling (1-2 weeks ago)... sucks... highly doubt it, but would that affect cold starting?
