i got a 96 ford, contour, and have been having problems with it.. think
i got it narrowed down to the igntion coil( i have a distributor-less
engine).. the coil is the thing that the spark plug wires are attached
to... i checked it today and found that i am not getting any power out
of the No. 2 and No. 6 wire.. i got a reply from a web site that the
coil works with two wire postions together, thats why the 2 and 6 are
not firing and it seems that the coil is fried.. i also have the wire
insulation under the hood messing up.. i know about the recall, but
would like to know what controls the coil to tell it to fire to what
wires( unlike the old distributors where the rotor turns and makes
contact to each spark plug wire) what determines what wire will be
firing???? is it the crank position sensor or some other sensor?? and
how do you test them??? i dont want to put another coil in the car and
find out that it did not get to the root cause of the problem...
thanks for a reply.....
First, check out www.contour.org. They know the car inside and out.
Odds are you need to replace the coilpack. I would guess each coil has
it's own control wire. You could try a quick test of simply unplugging and
replugging all connectors just in case one contact has gone bad (with the
power OFF of course!!) If the other two coils are working, odds are the
sensors and computer are working. I no longer have my manuals (I used to
own the related Mercury Mystique), so don't know what might be between the
computer and the coilpack.
The computer tells which coil to fire. It's based on the cranskshaft
position sensor, among others. One plug is on the positive side of the
coil, the other on the negative. In fact, in some years, Ford used
different spark plugs depending on which side of the coilpack it was
connected to. This was a cost-cutting measure as the difference was which
electrode was platinum. It has to do with the direction current flows. The
recommended replacements have platinum on both electrodes of the plug.
If there is a no_junk in my address, please REMOVE it before replying!
All junk mail senders will be prosecuted to the fullest extent of the
thanks for the info, but whatever it is, on mine is looks to be the No.
2 and No. 6, as there was no power from 2 and 6 and a new coil solved
the problem..... looking at the coil pack from top was like this:
4 6 5
3 2 1
so this might make me think that with the 2 and 6 not working and
being one ontop of the other and someone quoted from their service book
might tend to make me think that they are correct, but it does not
matter as the car is running now.. thanks anyway....
