Relay?
Volvos are known for having bad relays.
First step is to determine if the problem is fuel or electrical. To do
this,
when the vehicle will not start try spraying carb cleaner in intake to see
if it will start. If it does check the fuel pump power and fuel pressure.
If
they are fine check injector pulsing with noid light.
For electrical check and see if the positive side of coil is getting power
when it will not start. If so then check to see if plugs are getting
spark.
Then check to see if the injectors are triggering.
Doing this will quickly narrow down your problem.

My brother-in-law has a 1991 740 Volvo sedan that is starting hard, then
dieing once warmed up. Will not re-start until it cools down. He is
thinking
the coil may be going bad, or one of the many sensors - does anyone have
any
thoughts as to what the problem may be?
Thanks
