Still won't start, stumped

[Vince3031]

I have a 1998 S70 glt 2.4 turbo that seems to have a whole family of Gremlins, short summary. So someone try to steal it and I have been driving it just using the electrical side of the switch. Was driving fine and one night it started missing here and there, made it home and when I tried to start it the next morning it only ran for a few seconds. I've changed the ignition switch electrical side. Ive also changed the rotor, distributor cap, plugs, throttle position sensor, fuel pump, fuel filter, fuel pressure regulator (aftermarket bypass style) still won't start without starting spray, it will run when you spray it. So I don't think really an electrical issue and it's getting compression it's getting fuel to the real I'm not sure of the pressure I don't have a gauge. I don't know what else to do so any help would be really appreciated. oh yeah MAF sensor had went bad but car was running without it hooked up.

Have you checked the FP relay?
