Add a double dose of brand name diesel additive, and or ATF, run a few minutes and shut down.
Remove the OUT banjo bolt, inspect its screen for debris or polymerized veg oil, and wash it out.
Put it back together and give it some more exercise, or sleep on it...
Fair chance of it working much better after a day or a week.

Also be sure it is an out bolt at the out position, and not one at the inlet. They are easily recognized by the OUT stamped on the head.

PPS; If there are any bubbles in the return something isn't right. Running from a can, there aren't many sources of air, mainly the 17MM pump drive shaft seal and the fuel filter. If you rig a lift pump, it will pressurize the case, and you can see any suction leaks as a drip. 5-15 PSI should run fine, and 60PSI is within normal operating range if you just want to pump it up and look for a leak.

Ive had 6-8? pumps, and not one has ever had a good cold start. I don't think it's much needed in CA.
