he says I can drive it when I fix it ... so i better not fix it as I might not want to go back to mine ..

Thats a loaded incentive, he probably wants to drive yours. Unless it has carbs, it's not a lot diferent than a SC.

We used to have a coupe of old Ford trucks on the farm, and one of them did that. It turned out to be a bad coil. The other one did that also, and it turned out to be a rusted out muffler. The muffler partially caved in, and a "flap" would shut off the exhaust flow.

whalebird

Ice, you may want to check the muffler LOL. Coil sounds plausible though.

rusnak

That's what I thought too, especially given the fact that it will start up again after it cools down.

theiceman

is the coil the same coil as mine ? I also happen to have a muffler hanging in the garage .... but you guys have me thinking now .. what if it is the cat ..

I sold a car to a lady who just kept driving it. Never tuned it up, no plugs, wires, filters. It died on a big bridge over the Hudson River during rush hour.

If he has had the car a year, and never has done a lick of service, start there. Do the simple obvious stuff first. You may never figure out what the problem was, but you may find it is gone.

theiceman

The guy who sold it to him is the guy who installed the 3.2 so i don't think it lacked in maintanance , it's just broke .. that being said however I am a firm believer in start with the obvious..

whalebird

When you look at it, start at the battery terminals and make sure it's all good. If you see a bunch of crimp locks/butt conectors in the trunk/dash/engine bay...you may be dealing with a multiheaded dragon. Good luck.

Here are test values for the coil (taken from the Bentley Publishing Forum):

Primary resistance: between terminals 1 and 15 = 0.4 to 0.6 ohms
Secondary resistance: between terimnals 1 and 4 5.0 to 7.2 k-ohms
(Table b missing from the manual)

Sensor Testing: (sorry for the multiple posts)

rusnak

CHT values: (the white socket, top position of the 3 shown in the above picture)
0C 4.4 to 6.8k ohm
15-30C 1.4 to 3.6k
40C 1.1 to 1.3 k
80C 250 to 390 ohm
100 C 160-210 ohm
130 C 90 ohm

That is great info Russ .. although Mr. Bentley might object .... I now have the info to proceed thanks ..

rusnak

Now I should plug the Bentley Publishing manual I guess.
