If the engine cranks but will not start, it may be due a failed distributor. In the diagnosis, it may be discovered that the Electronic Engine Control (EEC) Unit is the cause if ignition spark is restored after disconnecting the Spark Output (SPOUT) Connector.Google+

Mine has a 5 speed manual. was stuck at walmart for 3 hours this morning because my 626 would crank but not start. A couple of days earlier had similar experience but got it to start after about 30 min. this happened 3 different times.At walmart I checked for spark, took a phillips head screw driver stuck it in 1 of the spark plug boots I pulled out of the valve cover and layed it near a good metal bracket. saw 1 spark when i 1st cranked it,then nothing. finally got desperate,decided to try to POP start it. had the key in the RUN position got it rolling pretty good,hopped in pushed down the clutch,threw it in 1st gear ,let out the clutch!! NOTHING!! for the hell of it i turned the key. wouldnt you know it fired right up!! maybe it is the ECC? I was thinking ignition switch? not solved yet,will try to let you know.
