Chevrolet Repair: 1997 Geo Prizm, cranks but will not start, not getting spark, 1997 geo prizm, distributer cap

Question
I have a 1997 Geo Prizm, the engine cranks fine but it will not catch. I was giving
me some hard starting problems (cranks fine, but not starting) so I replaced the
Spark Plugs, Distributor cap and rotor. Which did not help. The engine cranks
fine but will not start. At night I pulled a spark plug wire at the distributer cap
and had friend crank it but could not see any spark/arcing. Any ideas. Thanks

Answer
did you check for dist. referance from the ign module. try checking for spark from the coil. if you have no dist referance from the module change the module. if you have referance from the module but no spark from the coil check for a dist referance to the coil. if you have dist referance at the coil but no spark change the coil.
