Hello there. I have been searching thruogh the threads here and have hit and missed on a particular problem. I own a 87 xt gl 1.8 mpfi 2wd that lost spark. I got the spark back about an hour after it first died even though I didnt work on it, then it died for good. I have replaced the coil, optical pick up, plugs, wires, cap, and rotor. i have the signal to what I believe is a transistor mounted on the coil bracket but have no spark. The two blade plug goin to this "transistor" has voltage until the signal comes around from the crank angle sensor like I think it should. I beleive this "transistor" may not be pulsing the coil like it should to build current and release it. I'm at my wits end and running out of cash. If someone out there has experienced a similar problem or can tell me where to purchase one of these " transisors" if thats what its called, I could sure use some help. the chiltons manual calls out a condenser, maybe this is what im thinking is the transistor.
