I’ve been having trouble getting Evita started after warm running, which then got really hard after filling up. Checking latent codes showed a p0440 pending, so we start with …

Visual Audible Tactile inspection of the evap System.
Results- canister and hoses all good, they were reworked a few years ago with OEM

Purge valve hose inspection revealed this

In addition , removing purge valve and testing for glow showed is stuck open, it should be Normally closed with no voltage applied.

I used some J309 fuel line as a new piece and a tight Oetiker to get a lamp onthe hard purge line.

All good!

Now she is giving me a hard cold start, with some black smoke. ECT is new from Volvo, but I’ll check resistance.

After rough running for 60 seconds she settles into a sewing machine smooth idle amd runs with good power

I use chsnged her oil again, and this is a short trip car, I wonder if she is getting lawn mower syndrome. Abby will drive her this week and report back
