So, here is my sad story.. with my 1986 TII

just finished rebuilding my 13b, started up and idled very smooth without any issue. I took it out of the garage to hose it down from all the dust thats collected over the past few months and this problem started.

at first the motor wouldnt turn so i went underneath and moved the signal wire to the starter, awsome. but not it seems like one or more of the spark plugs arent firing.

i took out the spark plugs and the plugs on rotor 2 are wayyyy cleaner then the spark plugs on rotor 1. there are signs that the spark plugs were giving off spark.
so now i have no idea.

i noticed my EGI fuseable link was blown so i swapped it and still same problem.

i dont get this rotary world you guys live in, please send some guidance in my direction and i will be forever greatful <3.

thanks guys.

 

Check for any bare wiring that may have caused your EGI fuse to blow.A common place that the wiring will get messed up is behind the alternator where it gets hot.
If your EGI fuse is blown you are not going to get the car to start.
..??..Did the car's engine not Roll over when you hit the key,or is it just rolling over but not starting up?

 

Considering the leading plugs use one coil and the trailing plugs each have their own separate coils, it is not very likely that only one single rotor would have spark. (As long as the spark plug wires are properly installed.) - The leading spark plugs fire at the same exact time.

Be sure your spark plug wires are correctly placed from the coils to the plugs. Your car will still run on two plugs. (As long as there is one plug sparking on each rotor.) - Are you getting any sort of response from your tachometer?

 

engine fires up no problem, i did replace the EGI fuse. engine turns over no problem.
the engine harness looked fine to me when i had the engine out and it hasnt been in there for long.

the engine did run perfectly at idle, i even took it around the block a few days before.

the tachometer reads fine, idles around 1-2 K rpm. I did a resistance check on the coils and the results were fine.

i never re-arranged the plug wires since it idled perfect so they have to be correct.

Im thinking right now that maybe the crank angle sensor might of slipped... possible ?

 

another concern i have is why the hell the plugs on rotor 2 are so damn clean compared to the spark plugs on rotor 1.

motor runs realllly rich, typical i know. but it dosnt make any sense to me how this could be possible

 

Maybe the Rear Primary Injector is clogged or not working efficiently.

 

Injectors were flow tested and came out in good condition.

I tested for spark today and turns out the spark plugs on the front rotor had a very weak spark. The spark plugs out of the rear rotor sparked really well. I'm going to replace the plugs and see what happens.
