1989 Volvo 740 Automatic 160000 miles

The last 3 days I have noticed a little hesitation when starting my car but it has fired up everytime until this morning. I went to start it. It turns but won't fire up. I don't know if this has anything to do with it but it has been raining for the last 3 days too. It rained all night last night. Any ideas.
Do you

Do below to determine what's causing it could be fuel or spark issue

Get a helper disconnect a sparkplug wire or 2 and ground it to the engine at least 3/16 away from ground -have helper crank engine over-do you have a snapping blue spark? If so-you have a fuel related problem, check the fuel pressure to rule out the fuel filter/fuel pump/pressure regulator and listen to the injector/s are they pulsing or hook up a noid light. No snapping blue spark continue to troubleshoot the ignition system-power input to the coil/coil packs, coil's resistances, distributor pick-up coil, ignition control module, cam and crank sensors and computer Note: If it doesn't apply disregard it.
