92 ford ranger with a 2.3 distrubtless ignition.Ignition modules checks out fine. Replaced it anyway just to be sure . Coil packs checked out fine still no spark?Any idea ?

. Check for codes.
. Check for faulty crankshaft position or camshaft sensors.
. Check for faulty PCM.

I checked with a code reader. No codes present. How do you check the crank sensor?

To check the crank sensor, it is easiest to use a scan tool while cranking and monitor RPM's.
Are you getting power to the coilds? You should get battrey voltage at the coil on the R/LG wire (Red w/ Light Green trace). That comes from the ignition switch.
But if the crank sensor doesn't tell the ECM that the engine is turning, the ignition module doesn't know then to fire the coils.
Pinpoit diagnosis is crucial to properly diagnose the fault.
