1994 Toyota Camry 102K miles 4 cyl Auto Trans. Currently won't start, no spark.
Problem Started months ago by car just dying while on road at 35mph. Would restart after a while.
Think fuel we replaced filter. Seems to have plenty coming out while cranking.
Change cap and rotor, plugs and wires look OK. Still no spark. Check Ign coil got proper ohm reading across pos & neg also OK across pos and high volt terminal. Also swapped coil for new one, same results, no spark.
Pulled distributor and checked ohm reading of pick up coils per book both in spec. Also read coils while turning distributor shaft and when lobe passes coil ohm reading is interupted. Appears that is the way it should work, would be the sending signal I guess. Also checked air gap OK
Placed jumper across pins on data connector and got signal 12 flash on eng lite in car wich would be No NE Signal to ECM, yet coils read out OK and during distribuor turning we get interupted ohm reading?
Also got good voltage reading at ECM, can't remember which pins and also good voltage reading at Igniter.
Could distributor housing still be bad even with good pickup coil (NE & G) readings? Or ECM even though we are getting 12 error code?
This is a self repair as we cannot afford to just replace all parts as they are all expensive and dealer repair is more than car is worth.
