Cold start issues.

That’s a brilliant idea. You know I never thought to try a can of starting fluid. Heck I’ve got two in the garage. That’s by far the best “base” test. (I was looking too far inside the box vs looking outside of it for somewhere to start).

Thanks

One question about the ECT. If that were faulty, wouldn’t a check engine light come on? With an error code?

I had a similar problem with my 2004 S80 T6. Only hard to start cold. My service department found a intermittent failure of the crank sensor. They said this I a known issue. When cold the contact was intermittent, and once warm the heat expands the area of trouble allowing contact. It didn't make sense to me, but fixed it. June

Hmmmm. If worst case scenario, I’ve heard of other bizarre issues taking place when said “crank sensor” acts up. Depending on where it’s located and degree of complications involved I can probably do it myself. Was the charge you got from the stealership a hefty one? Just in the event I need to bring it in?

$311.66 plus tax at my dealer. As I remember I waited for hours for the job to be finished so likely it was hard. Best part if it breaks again Volvo gives a lifetime parts and labor warranty so it will be on them... June

I've never heard of a bad or failing ECT setting a CEL. That's why when it tests out of spec you need to replace it. Also why it's difficult to diagnose, because you have to test it.

Relay confirmed. Did the relay room temperature/ relay -7 in the freezer. Worked warm twice. Before and after freeze. I’m ordering an ECT just to have on hand. Thanks everyone for all your advice. It’s greatly valued!!
