when motors sit for long, I always 'pulse' injectors with a pigtail/12V
some you won't hear click. Tapping on injector body, while pulsing 12V..... often revive 'em.
cuts down cranking time tremendously, from my experience

even when my mitsu 2.4 sits for 4+ weeks, ONLY if I remove the brake booster vacuum hose(going to the intake)....
I pour 2 caps of gas in the hose, then blow it thru. Wierd, I know, but fires right up, everytime!
