I would check for other issues.....the code 12 is ussually a "ghost code" that will show always with engine cranking but  not starting.  Code 11 and 13 are common too.

 

Check your distributor rotor for being tight, and that it spins when engine cranked over (verify timing belt).

 

Then check for fuel pressure to the rail, and pulse of the injectors.

Probably a bogus code... well, maybe useless is more accurate.  "No start" conditions are notorious for their unhelpful codes.

 

Check to see if your distrib-rotor's set screw has backed out (I a assuming a particular type of  distrib, one with a screw-down distrib-cap).  Actually grab the rotor and see if it can be turned or pulled off. 

 

If this is not your problem, disable your ignition electronics (disconnect the distrib connector, and crank the engine over, watch ing to see if the rotor turns.  If it does not, then your distributor-side timing belt is broken.  If it does, remove the rubber plug covering the holes in the non-distrib-side belt cover, and check if that belt is snapped.

 

If all else is good, try using a spritz of starting fluid to see if it is fuel related.

 

Good luck.

the rotor, looks ok, it's moving when is cranking, and the spark plug wires are like a month old ( i pull a wire out, and has spark), and the car has a good fuel presure...

Disconnect the intake tube from the MAF to do this.  DO NOT spray through the MAF, DO NOT leave it hooked up and spray though a PCV line. 

 

Disconnect it from the MAF and shoot it straight down the tube.  A backfire can destroy the MAF if you leave it connected.

Check power 12v to Injectors with Key on/eng off.  Pulsing while cranking.

so if this code 12, goes together with 11 and 13, this

Crankshaft Position Sensor, should be replaced, in order to use the loyale? :wacko:

Timing is correct and the plugs are firing means to me you have a fuel problem. Check for a blown fuse and check to see if the fuel pump under the RR wheel is working.

Those all happen during a no start condition.

 

The Crank and Cam sensor are really the same thing an ea82....part of the distributor.

 

Check your injectors for 12v with key on. And check that a test light hooked to it pulses during cranking.  Seriously.  The computer is not going to tell you wahts wrong you have to find it.

I agree to check for a blown fuse. Whenever I have a crank (but no start) condition, I always check the "HAZARD - HORN" fuse under the dash. For some reason, if that's blown, it won't start. I especially had a bunch of problems with this when I had aftermarket horns installed.

The starter switch is the starter solenoid.

Code 12 means the computer has not seen 12 volts on the B/W? wire,and did not know it was supposed to be in start mode.

 

Are you sure it was not code 11?

11 is normal on a no start.

 

Your 86 EA-82T does not have a crankshaft position sensor like later ones.

 

Fuel pressure is good,but how good? psi?Plugs wet?

this problems start when I change the pcv because the old one was leaking oil to the intake, also I replace the air filter, but everything was put back in place, even every little vacuum hose, today when I rechecked the car has spark but looks like is little weak, and the smell of the gasoline fill the air, so looks like I´m having a wet spark o a bad coil....

 

thanks for your help

The starter switch is the starter solenoid.

Code 12 means the computer has not seen 12 volts on the B/W? wire,and did not know it was supposed to be in start mode.

 

The code means "continuisly in the "on" or "off" positions.

 

If you are cranking for many seconds, and the Ig. is sparking, the computer goes  ...."wait.....I'm making spark and should be running, but the starter switch is still cranking"   Throws code for starter switch.

 

Old electronics have dumb logic.

Good description of code 13,not 12.

12 is starter switch never on.

13 is starter switch always on.

Are you by chance using a pushbutton for Starter?  If you are, and you did not reconnect the original starter wire to the new one, then the computer is not seeing voltage during cranking.

your 86 should have a vane or "flapper style" maf if its faulty it will not start. theres basicly a door that opens with the airflow.

 

unplug the maf and see if it will start. it will show a maf code.
