My 87 RX7 is getting no spark. I replaced both ignitors/coils, crank sensor, and computer. Any ideas guys?

pulled plugs, grounded plug, no spark while cranking. Also stuck finger into igniter and cranked, no spark.

haha, thats dangerous... Well the ecu gets its signal from the Crank Angle sensor. Try replacing/checking that..

if one leading plug is fouled neither one will fire. they are on the same circuit. basically the cas tells the ecu when to fire the coils.
