I.m getting a code 12 which is my distributor. I'm also getting a code 51 which is my throttle position sensor. If my throttle position sensor was bad would that stop power getting to my coil and distributor. I've changed wires cap and rotor and coil. Still no spark at my coil.

 

have you ohmed your coil and checked the air gap on the dist. have you checked the TPS?

 

The dist looks scary.It is all corroded but i'll air gap it in the a.m. It's been snowing since sunday and I'm working outside. Any way to by-pass the tps.thanks for the help.I ohmed the coil it's brand new today 0.4 cold

 

I'd had some ignition problems and started a thread about it. The TPS wouldn't cause it to not fire, but would certainly cause running issues. The TPS can be unhooked and the vehicle will still run, just not as efficiently. But, you need to comb the ignition system to see why no spark. Maybe this thread will help.

I provided a link in the thread that goes over testing the coil and igniter and distributor. Good test....and not too complicated.

BTW, corrosion at the distributor pick up will definitely cause problems.

 

I had this problem on my 4Runner about 3 months ago. Code 12 indicates that one of the pickup coils in the distributor is not sending a signal the ECU can understand. Check the resistance and if it is above 180 ohms (IIRC), then that pickup coil is bad. I was unable to find replacement coils and had to replace the whole distributor.

 

You are right Gonzo.I air gapped the p/u coil and came out with copper wire on the feeler gauge. Distributor is out of the truck.and I'm going to make some calls now . I printed up a fsm last winter when I found this site.It sure is saving me now

 

When you get the new distributor, put some di-electric grease at the terminals and back of the connector to prevent corrosion again. Wouldn't hurt to do that elsewhere.

 

will do that and thanks. Where did you find your new distributor?

 

Oh...I didn't get a new distributor (mine is good)...just a new ECM. That I bought from the kind fellow in the link in my sig.

 

I figured it might be your distributor, pete.

I got my distributor from a wrecking yard for about $75. One would be about $140 for a rebuild or $200+ for a new unit from a store like Kragen.

 

He went to NAPA already. See other thread.

 

I got a new one from napa for $260.00 with new p/u coil.They are shipping it overnight and it will be @ the store @ 8:30 a.m.I just hope this is it. This ordeal is cramping my deer hunting. Good for the deer.
