Hello Rob,
Before condemning the new injectors, try 1 more test.
Retry the same pressure test you just did, but this time also pinch the fuel hose going to the cold start injector. If the pressure holds this time then your cold start injector is leaking and not the new injectors. Don't forget to remove the 2 clamps before you cycle the fuel pump again to re-pressurize the fuel rail.
FYI, my major supplier of aftermarket parts is VP and most of the time they sell good parts. I get a small discount, so if you order through me, I can make a few $ too.
Also, not everything VP sells works well and after 30 years of repairing Volvos, I can steer you towards some parts they don't sell or warn you if they aren't up to snuff.
I have to admit there are some parts I would rather not sell or recommend, but in some cases they are the only thing available. For instance the door seals for the 122 2 door Volvos are now made of 2 pieces of extruded rubber bonded together at 1 corner. And although they do work somewhat, the original door seals were made of at least 5 pieces and at least 3 of them were made in a mold and then bonded together. The molded pieces had special shapes that conformed better at a few critical areas along the back edge of the door. Unfortunately, the seals Volvo now sells for the 2 door 122 are made the same as VP sells.
BTW, if you had found me before VP, I would have tried to sell you used original Bosch fuel injectors that have been cleaned and flow tested. Each refurbished injector gets a new internal filter and a new pintle cover. I also include the correct sized seals. I also stock injector stand seal kits.
I get $50.00 per injector plus a $20.00 core charge per injector.
