84/85 hot air spark module

[jimski]

Which wires on the spark module plug should have 12 volts.I know the pink with black should both have 12 volts which others wires should have 12 volts besides the crank and the cam sensors wires.

Pink with black stripe is the only wire with switched 12 volts. Black/white is ground, blue is sensor and yellow with black stripe is pulled up to around 6 or 7 volts thru the ECM.

My problem is that pin p and pin n have power but there is no crank sensor power coming out and no cam sensor power coming out at all any suggestions.Just was wondering what other wires should have power to the module besides pin p and pin n. it seems that no power is coming out of the module to the crank sensor and no power is coming out to the cam sensor.The car will nort start.

Aah, ok you're referring to the CCCI module, not the ESC. The outputs to the sensors are internal, so if you don't have around 12 volts at the gray/red wires, the module is defective. You could jumper the 12 volts (pink/black) to the gray/red wires - 8485 only - but that's a band aid. You need to find out why the sensors lost power, generally an internal failure due to a short.

At first the ecm terminal a6 did not have power but when i put 12 volts direct on a6 on the ecm, pin n on the module plug gets power now. But still no crank power and no cam power coming out.I am not sure why terminal a6 has no power with key on the ecm fuses are good and the orange wire is conected to the battery. jumped it basicly now pin n gets power on the module but nothing coming out.anysuggestions

You had originally said the module was powered up with the pink/black wire, both locations.

If you don't have power there until you manually power the A6, it would be a bad fuse. Replace it to be sure.

Check the MAF because it also shares the same fuse feed.

Still no power at the cam and crank sensors suggest a defective module.

Could the cam and sensor power wires be jumped with power to hot wire them as suggested above, just to see if it runs,im working right now to get a new module coil pack.Thanks for youre help here this has been making me mental.

"check the maf" what is this.Could the cam and sensor power wires be jumped with power to hot wire them as suggested above, just to see if it runs,im working right now to get a new module coil pack.Thanks for youre help here this has been making me mental.

maf is your mass air flow sensor by the air filter. I am having the same problem and just want to hear it run to see if I need internal engine work before I go further with the project.
