Newbie with a Montero

Hey, guys, I'm Eric...I have a '91 Montero 4x4 that was just given to me a few days ago because it doesn't run. I'm not really familiar with Mitsubishis in general, but it cranks and there's no spark. I'd really like to get this sucker runnin fairly soon, since the rig is mint and I wanna get to patrollin the mudholes

anyhow, I was just wondering if any of you knew how to test this optical ignition system on the 6G72 SOHC V6's distributor, and if not, who can? Could the no spark problem be the computer, too? thanks.
