Why not contact the Volvo Owners Club forums for advice on your problem. URL is http://www.volvoclub.org.uk
On the index page there is a link on the left hand side for Forums. Click on that and register yourself as a forum user. Then you can access the forums. Technical problems for your car would be under "700 series". Also the Brickboard FAQs are accessible from the VOC site. Same URL, link also on index page. The main problems with 740s are the fuel system & ECU (both pumps, fuel pump relay and radio suppression relay [this actually should be named as injector relay as it is part of the circuit for all the injectors] and the ignition system & ICU ( timing sensor(s), distributor, coil and leads, spark plugs and ignition amplifier [this drives the coil, but sits between the air filter and the left hand inner wing] which usually suffers from corrosion and poor connections, mainly earthing ones.
It only costs about £25 per year to join the VOC, this can also be done from the VOC site via a link on the index page.
All the best, Peter.

Hi, I'm new to this forum.
We are living in England and have a petrol Volvo 740 Estate automatic.
Recently it's been reluctant to start on cold days. Our initial thought was ice in the fuel so we added something to dry out any water in the fuel. The engine was turning over fine but failing to start.
This week the problem has begun happening when the car is warm as well as cold.
We were able to drive into town 2 days ago, parked for 10 minutes, then the car failed to start with a warm engine. The breakdown chap said it wasn't an ignition problem as it was turning over fine. However he gave us a boost that did enable the car to start. He said everything pointed to fuel pump relay.
We later changed the fuel pump relay on Monday as this is apparently a common fault in Volvos. It then began starting intermidently and would start on the second attempt. This morning again it failed to start. Each time we try to start it we hear the in-tank fuel pump doing its thing so I don't think it's that. Incidentally we took the case off the old relay and couldn't see any cracks.
It feels very much like a problem to do with not enough fuel getting through to initially start the car.
I have to stress that once we finally get the thing started it runs very nicely and doesn't stall or misfire at all. This must surely rule out lots of common problems.
Any advice, or anyone had anything similar? We have 6 children (one of whom is a baby) and really rely on the car on a day to day basis for transport.
