No Earth on Coil, 1997 Ford Falcon

check the earth again dont rely on the fact the engine turning means there is an earth.

get meter on Ohms connect one lead to chassis and other lead to clean metal on engine and report findings

The Ohm reading between body and engine is 0,01 ohms. With the continuance tester i also get a clean reading. this is how the problems started. The car didnt want to start, but when we tried again after 30 min. It did start. About a week later it did the same thing, but refused to start, No spark at the sparckplugs. I changed the coil with no result, tested the old coil, which tested fine. tested the module, which tested also fine. Ive put the old coil back, but before connecting it i tested between the coil leads, while the engine turns, i got a pulsing signal. After i,ve put everything back again. The car started. it was idling nicely for about 4min. Then it just cut out. But it started immediatly again. I drove then around for about 50 km. While driving 2 days later the engine just died. No spark and no earth pulse on the coil earth lead. The coil possitive is fine.

I don't know if this matters, but the last production year of the Ford Falcon was 1970.

In Oz the Falcon as a brand lives on. Although you North Americans wouldn't recognise it as it is very much "home grown".

The inline 6 has it's origins in the non crossflow 250 as found in the 1970 falcon, though I dont think there is much that would interchange between them now.

Ga from me- Is the Falcon in Oz still being produced by Ford motor company? Or did they sell off the name to an Australian company? Just curious.

We don't hear much about what US car companies are doing abroad. I know the info is available, it just takes a little digging around.

We actually have Ford here as an auto manufacturer

And yes they're in competition with the local GM outpost Holden.

I'll be damned. Thanks for the links. They are a lot different from the old Falcons (60's), that we used to beat around in, in the US when I was a kid.

Please explain what a KFC burger is. This side of the world knows KFC as Kentucky Fried Chicken.

I am so going to start a thread on explaining the subtleties of our various cultures.

In Oz, KFC is Kentucky Fried Chicken. They did a name /logo update about 10 years ago to reflect how the brand was colloquially known. Also if you had to say Kentucky Fried Chicken 10 times in a 30 second ad there wouldn't be time to say anything else...

The burger is just another part of the menu, they offer it in both original 11 herbs & spices or the "Zinger" which is a spicy chili version. The burger uses breast fillet and has an assortment of salad incorporated much like a hamburger

Im in south africa. The ford falcon is not well known in south africa, but there is a couple of them on the roads, which were imported from Australia. So the parts and technical support are very scarce. But its still Ford. I havent seen any Mazda or Mitsubishi parts on the falcon.

Ive measured the coil, and i found a reading around 13 ohms on the primary coils. When i tested the wires goeing to the the coil, with a test ligt, i found tha the possitive is fine to the engine earth. But the earth lead going to the coil is dead, when i crank the engine, it gives a weak earth, but when the starter stops turning it gives a solid earth for n moment and then nothing again.

All of the symptoms you have posted could be caused by a bad ignition control module. In the states, the below design Ford module was noted for sudden failures of the nature you describe. Many times it was heat related, and an emergency repair could be fashioned by pouring cold water on the module, and it would restart (till it heated up again). Does your module look like the finned aluminum box pictured below. If so, bite the bullet, and replace it with a new module. Good luck.

Sorry, No picture. Lost in computer.

The module sits on the side of the distributer, and more a darker colour than aluminium. It has 3 connections going into the Dis. And 5 connected to wires. The car is standing since the weekend, and it still doesnt want to start.

This is what we here have come to know as the thick film module. They were not as prone to failure, but still common enough. There is a special thin wall socket needed to change them. Make sure to use the special heat transfer compound when you change it. Make sure to inspect the harness where it connects to the module, I have seen corrosion in a few of them. If corrosion is present, use a stiff brush to clean as much as you can, and then protect with a dielectric grease. Good luck, and I vote for changing the Module.
