Help! No spark!
Yesterday I stopped on red and engine stalled. I triet to start it again, but unsucsessfully!
No spark, no pulses on coil.
What may it be? May be Hall effect sensor ore may be coil resistor (I dont know where is it located?).
How to find problem?

'89 3.0 EFI! Yesterday I tried to start it. Egine started, but idle was rought. Stalled in 1 mile. I tried to start again, but battery was low. I want to get osciloscope to check PIP signal. I've heard, sometimes coil resistor may cause this problem, but I don't know were is it? May be my TFI went out. So what a procedure to find a problem? I don't want to replace good parts.
I think about engine swap. My engine is OK, but I want to get turbo-diesel. It seems to me Mercedes 2.4 R4 diesel is the best for aero. But it costs here up to $1000 with tranny.

Yes! It is TFI! PIP signal is good! I tried to use russian TFI for 4-cyl engine, but idle is not good and it is strange, but there is no spark on cyl #4 (I can see it on osciloscope!). May be I know why. Russian TFIs makes spark when PIP signal changes from +5 v. to 0, and pulse of cyl #4 is shorter, so spark timing on cyl #4 is not correct. May be original FORD TFI sparks when PIP changes from 0 to +12 volt....
Tommorow I wanna try to find original TFI in Lugansk. Finaly its time to drive to dealer....

I had to drive to dealer. TFI is $120. But the gue said, that he has a distributor from Bronco, used , but for $20. So I replaced TFI, and my old lady runs well. I want to take this distributor apart, but I dont know how to remove a cam wheel.

Sorry for what must sound like a simple question, but what is a TFI and waht does TFI stand for? Is that the little plug-in module at the base of the distributer? I had one of those things in an older Escort that left me stranded once. I remember having to use a small mirror just to locate it and several bandages to change it.

Look! I have distributor from 2.9 V6. This distributor does not fit aero, but TFI from this distributor is on my ero now. I want ro have spare hall effect sensor, but I dont know how to remove it from distributor of bronco. To replace my is easy! I've heard press is required, but I had never did it!

What caused the TFI death is excessive heat due to its location. The solution is to move it to either the passenger side fender or the radiator support. I belive the ford dealership should have this. It may even be free.

Kan! I've taken TFI apart! Card is broken! How to relocate TFI? There is a thermo paste under the TFI. Body of distributor is used as radiator. But lets look at this situation again! My TFI is 17 years old!

replacing Hall sensor> snip
"Notes: I have personally experienced a failed Hall Sensor. This part was very difficult and obscure to track down. It took one year of problems to finally track it. Trends I noticed were the following: The car would just stall for no reason and would not start for maybe 5 to 10 minutes. Sometimes, it was just difficult to start. It seemed oversensitive to humid weather and died a few times in the rain.
The car would intermittently lean backfire or start running poorly. In one case, it backfired several times one night, at which time, I got really aggressive at tracking the problem. Replacing the TFI module is a 5 minute deal, but changing the Hall Sensor requires removal of the distributor and a shop to press the cam gear on and off."

moving TFI>
suggest air box or better yet in front of radiator on aluminum or copper heat sink block, use silicone heat sink compound from electronics store or any buddies that DIY large car stereo amps
old heater core may work well
use shielded cable to protect PIP, Hall effect and tach signals from ign. spark emf pulses

Pablo,
won't help you any in the Ukraine but indicates how bad the Ford TFI problem was here in US

There is a paste betven TFI and distributor! As I've understood for better cooling. Is it common thermo-paste used in electronic industry?
And what is averege life-time of TFI?
