Re: 96 SL2 turns over, won't start

ignition module wiring diagram - http://www.saturnfans.com/photos/sho...p/photo/18774/

check DIS fuse.

If you have a NOID light check for injectior pluse, if you have a pluse you can skip the next test, if you don't have a NOID light you must do the next test.

set multimeter on AC Volts, connect to crankshaft sensor. and crank engine. if you have no voltage replace or bench test crankshaft position sensor.

crankshaft position sensor bench test. ohms terminal to terminal = 900 ohms +/-200 ohm; terminal to housing = OFL; set meter to AC volts, connect leads to terminals, wave a peice of iron or steel infront of sensor(not alumnum) you should get some reading other then zero.

if the CPS checks fine but you have no spark and no injectior pluse you'll need a scantool.

check the ignition module connectior for ground at terminal B and power at terminal A.

if your multimeter is digital or you have a osilioscope and can backprobe- set for DC volts and check for a signal to terminals C and E(maybe 2 volts?, no more then 5)

if you have power and ground to the module and ether injectior pluse or a signal to C and E, but no spark, suspect the module(buy a cheap junkyard module to confirm)
