It sounds like you may have a bad thermo-time switch. A easy test for this is to remove the plug that goes into the switch and ground the wire with a jumper to fire the cold start valve (unfortunatly there are 2 wires, and I can't remember off hand which one to ground). If it is a bad switch, the engine should fire right up. On a side note: If the thermo time switch is found to be the culprit, then your best bet is to buy it thru DMC Houston. They list the switch @ $24.65 US. I've been to Volvo parts suppliers, and they usually demand around $50-60. I even called up my local Volvo dealership and they wanted $150!!! (I hope the dealership offers health care for it's employees. Because for that high a price, someone must have fallen and hit their head REALLY hard!) -Robert vin 6585 [Repeat quote removed by moderator]
