No power to distriutor

double posted, why?
I guess you are h3ll bent on gue$$ and not testing.
so keep going replace everything, we love to watch.
why not use the diagnostic jumper as posted in your other posting.
why>?
no spark out of coil right.
recap of last answers.
fuses, good, all 7 for ecu +spark good????????
we test them not guess, but ones that look blown are.
CEL Glow key on,?
flash codes ok 5 seconds cranked.
CKP good , the ECU will tell you its bad with flash codes.
why skip this key test??????????????????????????

The ECU must have power ! this is first. not changing out tons of stuff, 12vdc power,, and there are 7 fuses.
i bet you never tested them
or measure all ecu power pins to see if its has power first.
and is FIRST, no brain,(ecu)no spark and then no fueling.
if the CKP is dead, there can be nos spark.
ever.
I can only presume you connected a good new spark plug
to the actual coil tower point, then ground the spark shell.
and cranked and spark really is dead, 100 years, same way.
if dead, check 7 fuses.... seen in the book on car.
log in to mitchells diy. (google that)
and read how it works, its all there, read it.
a schematic to.

Hope this helps

Pick up coil inside the distributor . Did you test that ? B+ voltage to module , coil ? good ground ?

its most likely the ecm ecu control modual.

Do you have fuel, is your fuel pump working. If you do not have any spark at all, have you been able to check to see if you have power to your distributor. If so and you do have some then it might be either your ignition coil, pick up coil or your ignition control module. Your pick up coil in in your distributor under the plate. The coil is on top of the distributor cap. The ignition module is right under the cap where all your distributor wires connect to. Some part houses can test your ignition module and let you know if good or bad. Good luck.

Did you check primary voltage to ignition coil? red wire with lite green tracer, use a test lite to check voltage, goes hot with key on, circuit is fuse protected.

Test the fuel pressure at the test port when the engine is not running. The pressure regulator has a check valve in it to maintain pressure when the engine is off .

have ignition module tested, and if need be put on new coils. check distributor cap and and rotor for carbon tracking. the fault lies in the distriutor. have a good one !!

Check your fuses (ECM) and also recheck your wire leads to the coil. Your ICM (ignition control Module) may also be bad, it's located in your distributor under the rotor. You can have that tested also to make sure it's working 100%, there common to go bad from corrosion caused by condensation under the distributor cap.
Thank you for using Fixya and good luck.

start by testing coil for power ,if no power then in the fuse panel you should have anything up too three fuses marked CONT and they should be about 10 amp ,check them
