Describe the condition "will not start".
Does it splutter or pop slightly?
Or does it sound like there is no combustion happening at all?
I had a slight sputtering no start condition a couple of yrs ago.
Plugs were not wet, no smell of raw fuel at the tailpipe after cranking.
Sprayed fuel into the sparkplug holes and it fired briefly.
Loosened the fuel line at the injector rail and cranked the engine, it pumped fuel out.!
Injectors were clicking.
Plugs had strong blue snap.
No codes that I could pin down to cause a no start.
On a hunch I pulled the fuel pump, its Regina in the tank. Opened the pump up and it was toasted, I'm surprised it still worked at all. Brushes were burnt away, wiring turning into black ash. There simple wasn't enough pressure at the rail to get through the injectors. Replaced the pump and it ran perfect ever since.
Check that distributor timing and see if you're actually getting fuel into the cylinders. Put some in there to ensure it, if it doesn't at least pop the spark is too weak. There may be other problems.

Weak coil can make for weak spark, bad coil ground , bad coil HT lead to distributor , carbon in dist cap and so on.
Pull the vac tube off the fuel pressure regulator, look for fuel.
Be wary of pulling the tank pump, its a tricky job getting it back in there correctly, read the FAQ file very closely.
Especially this.
"When replacing the tank pump/sender assembly, put a little vaseline on the surface of the pickup that mates with the wide gasket surface leading into the tank. By then positioning the gasket into the tank neck and inserting the pickup unit the job suddenly becomes much easier - the pickup practically dropped into place by itself. It is also helpful to put the gasket in place after getting the pickup unit prepositioned without the gasket being in the way. The gasket will stretch around the pickup, allowing it to be added to the stack quite easily."
I fought with it for 9 hrs until I went back and read the FAQ. doh!

Try shooting some fuel into the cyl's directly, if it DOESN'T pop or splutter I would focus on ignition.
If you have a timing light set the distributor where it should be.
Testing the injector relay is as simple as feeling the injectors clicking. If they click the relay is working.
My fuel pump was running too , it wasn't until I pulled it apart and got inside it that I found it burnt up, so they can still run but be too weak.

Last year I ran into the same trouble with my 1992 940gl regina sedan. You WILL get fuel pressure but it won't be strong enough! The reason, as far as I could tell was that the fuel filter was never changed and it put stress on the fuel pump to the point where it finally was too weak to feed the engine.
The regina systems have only one pump and its in the tank, which means you should be prepared to replaced the hose clamps/hoses. Its not as big of a hassle to do it through the access port on a wagon, but I did it through the trunk on my sedan and my legs killlled from leaning over all day. If you want to diagnose it, take the line off the fuel pressure regulator and spray gas into it from a bottle while someone cranks the engine over.
One final thing, I replaced my pump with a spare I had from a 95 940, which is a bosch pump; I had to bend a piece of metal so it would fit in the more shallow tank. I've read some articles about the differences between the pumps and the regina system seems better overall, it smooths out the fuel delivery when the accelerator changes quickly. Now when I let my foot off the gas too quickly I can feel the fuel pressure drop and I've stalled the car twice from a cold start. Otherwise its not a big deal, and a new pump will cost you about 200 bucks, last time I saw it on a few nice online stores. Good luck!

Autozone sells the pump for $70 that fits the Regina.
The original pump , once out of the housing was an AC Delco with Volvo sticker.
My Regina fuel pressure regulator was expensive too so I just replaced it with the cheaper non Regina version for a 240.
