Volvo Won't Start

Many things can cause this on your 740. Fuel pump, fuel pump relay, rpm sensor, MAF sensor, radio suppression relay. I've never seen the coil fail on these era Volvo's, ever. And I've diagnosed at least 50 of these with stalling problems. Check the codes, and when it wont start, check for spark and fuel pressure, you're likely missing one of them.

The fuel pump relay is often the problem.
It's the one on the right of the two, above the fuses, behind the ashtray.
It's a VERY common fault.
But cheap to fix:)

Assuming you have a distributer cap/rotor setup are you positive when the number 1 cylinder is at top dead center that the rotor is pointing to the number 1 wire? You could have the order right but the wires on the wrong spots on the distributer. Also, if the cap uses a seperate coil wire, ensure that the coil wire is in place both on the coil and the center of the cap. An easy way to avoid problems like this in the future is to replace the wires one at a time.

I had the same problem when my battery went flat and tried to use jumper cables connected to another vehicles battery. I called Volvo and they said I need to disconnect the battery terminal to reset the computer. After re-conecting it the remote control worked again and I was able to jump start the car. Maybe your car's computer went into a similar state.
