Question about 1991 Toyota Corolla
I have a 1991 Toyota Corolla DX 4AF-E engine, approx 88,000 miles which has been sitting for a couple of years. I have put in a new distributor, new ignitor, new plugs/wires/cap/rotor. I am not getting any spark (screwdriver in the boot and put across a ground, no spark when starting). I checked the error code and I got error code 12 distributor rpm (NE) signal may be lost during cranking. I checked the primary and secondary power on the coil and they are within specs. Also I assume the fuel pump is bad as I am not hearing any noise when the key is turned, but there is power (12v) at the white/blue wire going to the pump. No fuel is being pushed through, and am assuming there should be some fuel going even without starting? The EFI relay seems to be working; I have also jumped the Fp B+ to see if the pump would work.

I had a prolem like this one time a while back. what i did was got the wiring diagram and checked everything that was running through that 30 amp fuse. on the one i was working on it ended up being an injector wire pinched under the valve cover and it didnt short out till the car was driven til it warmed up and expanded after the valve cover gasket was changed. hope this helps!

you need to determine if you have spark or not. if not, is the cam turning? does it sound normal whan turning over? take the oil filler cap off, and see if cam turns while someone is cranking engine. if not, the timing belt is broken. if you do have spark, then the engine isnt getting fuel. you may need a shop to get further into it.

My experience with Bosch ignition system (found on european cars) is the spark control is sent by the ignition module. The ignition module has to receive an input usually from a crankshaft sensor. This is usually near the crankshaft pulley on many cars. I am currently working on a 04 Toyota RAV4 and it has exactly that. If your sensor wiring gets loose or a bad wire then the computer won't signal for spark. This may not be your problem but it sounds like it probably is.
(By the way on my Alfa Romeo it is a sensor around the bell housing that senses the teeth on the flywheel) Good luck!

crankshaft sensor, or computer on toyotas then it was usually the distributor or the computer, but the crankshaft sensor might be bad too thats what helps to get you spark.
