Engine won't fire. With the key in the start position,I'm receiving 12+ volts of power to the positive side of the coil with neg. terminal of my voltage meter grounded to the engine. I'm not receiving hardly any movement with pos. and neg. terminals of volt meter attached to both side of coil. I have replaced coil, dist.cap., rotor, and ignition relay under seat. Battery tests fine....Starter motor turns motor fine and all electrical ground straps appear fine....Car ran perfectly until last trip when it started in garage....it took a couple cranks....usually for six years it fired right up......I've attempted to see if I am getting spark from the coil and to the plugs....I removed coil wire at distributor and saw no spark arching out of wire near fan housing, next I removed no.3 cylinder and spark plug and cranked engine with plug grounded to side of valve cover, this works with race motors on my boats and I saw no spark...Can one still determine spark this way on my 84 Carrera?......After several seconds of spinning starter I smell fuel so I am assuming gas is attempting to come in up the fuel rails.....You previously mentioned in another question the possibility of a cylinder head temp sensor.....those square boxes near coil....I've checked all fuses and everything on and under car does not appear out of place...Tonight or tomorrow I'm pulling examining the DME control unit....I'm sure something is preventing current from allowing the coil to fire the plugs???? Help me out...if you can make any suggestions just to get the car running.....I did do one thing (charged battery overnight with 10 amps)just to restore it....it was slightly drained from lack of use.....I'm thinking the current traveled into the system...I took charger off before even attempting to open the door!!!!!
