alanius Posted October 28, 2013 Share Posted October 28, 2013 We are competing in an offroad challange in Polland, yesterday the car went perfect: as a dream.Today he suddenly runs on 7cilinders. We checked the spark plugs and 1 was not ok. So for the safety we changed them all.All went ok for 10mins and the same problems again.We started to search further and found that there was no spark at all at that spark plug.We tried with another lead and stil no spark.Then we switched the connectors on the coil packs. Then we have a spark and both coil packs work as they should.When I change it bback again no spark.It is the coil pack where you have the green-brown signal wire.Do you know what the problem is? Engine is a 3.9 with thor mannifold.Could you pleaze let me know somethingRegarfs Quote Link to comment Share on other sites More sharing options...
FridgeFreezer Posted October 28, 2013 Share Posted October 28, 2013 Can you give more info - is this MS'n'EDIS, direct coil drive...? Did you build the ECU or did you buy it from someone? Did you switch the spark plug connectors or the low-voltage connectors? Assuming MS'n'EDIS: The coils fire a pair of cylinders per coil (4 wires, 8 cylinders) so it's quite hard for only ONE cylinder to go down, if one coil failed then TWO cylinders would fail.

alanius Posted October 28, 2013 Author Share Posted October 28, 2013 Hi Yes MS and edis. Bought the full kit from nigel, he build the ecu. I switched the low voltage connectors. And if you heard rhe engine there was only 1cilinder that didn't work, you also could see that on the spark plug. Quote Link to comment Share on other sites More sharing options...
Bowie69 Posted October 28, 2013 Share Posted October 28, 2013 Which cylinder is it that isn't firing? Quote Link to comment Share on other sites More sharing options...
alanius Posted October 28, 2013 Author Share Posted October 28, 2013 Sorry, if you stabd in front of the engine it is the second cilinder on the right side (counting from the front) Quote Link to comment Share on other sites More sharing options...
FridgeFreezer Posted October 28, 2013 Share Posted October 28, 2013 Are the connectors (on the coil & on the plug) all OK, clean, not loose, not pushed back in the housing? Quote Link to comment Share on other sites More sharing options...
alanius Posted October 28, 2013 Author Share Posted October 28, 2013 Jez they were all fine. The plug that didn't work we tried with a temporary fix to see if it would work but still no spark. And suddenly it all worked back again. So i dont touch it anymore. But if it happens again I know what to try. As I tried almost everything I know.

FridgeFreezer Posted October 28, 2013 Share Posted October 28, 2013 If you have rewired it to swap coils then you will either see the fault reappear on the same coil (dead coil) or the same cylinder/plug (problem with that cyl / plug / injector). Do you carry a spare coil pack, or can you find one? Plenty of small 4-cylinder euroboxes with compatible coil packs in the world. Quote Link to comment Share on other sites More sharing options...
alanius Posted October 28, 2013 Author Share Posted October 28, 2013 Do you know types of cars that uses those coil packs? Or that I can use as i dont have a spare one. So i can track a new one for spare Quote Link to comment Share on other sites More sharing options...
alanius Posted October 28, 2013 Author Share Posted October 28, 2013 Or type numbers Quote Link to comment Share on other sites More sharing options...
Bowie69 Posted October 28, 2013 Share Posted October 28, 2013 Any 4-cylinder Ford From late 80s/90s, fiesta, mondeo, escort etc. Though EDIS isn't fussy, and will run almost any coil pack you can find as long as it is wasted spark. Quote Link to comment Share on other sites More sharing options...
elbekko Posted October 29, 2013 Share Posted October 29, 2013 And good chance you'll find one in Poland, LPG everywhere so lots of petrol cars. Quote Link to comment Share on other sites More sharing options...
alanius Posted October 30, 2013 Author Share Posted October 30, 2013 Changed the coil pack and still the same. After some further searching I found that plug 3 and 2 didn't get any spark. So hopzfully it is the wire with the green stripe that causes the problem. How can I check if the EDIS8 module isnt broken? And from what car is this, so I can track a spare one. Or numbers so we can order one. Thanks! Quote Link to comment Share on other sites More sharing options...
Bowie69 Posted October 30, 2013 Share Posted October 30, 2013 EDIS8 are pretty rare in the EU unfortunately, if you want a spare, get Nige to send you one. They are VERY reliable though, be incredibly surprised if it had failed. 3&2 as you say are a pair on the coil pack, so sounds like you have a problem with wiring as you suggest, hopefully an easy fix, only goes from EDIS to coil pack.

alanius Posted October 30, 2013 Author Share Posted October 30, 2013 All wires are ok. So guess its the EDIS8 module thats game over? Or would the Ecu also be a possibility? Quote Link to comment Share on other sites More sharing options...
alanius Posted October 30, 2013 Author Share Posted October 30, 2013 In what kind of car you can find this EDIS8 module Quote Link to comment Share on other sites More sharing options...
Bowie69 Posted October 30, 2013 Share Posted October 30, 2013 V8 Ford's..... not many in EU at all, Nige gets his from the states IIRC. EDIS will fire the plugs without the MS ECU even connected, so seems to be that end, are the plug connections all OK? I have had two faulty coil packs which threw me for a bit once...

alanius Posted October 30, 2013 Author Share Posted October 30, 2013 Jes everything is ok for the rest. Anyone contact number from nigel? Or can sent one with DHL overnight? Quote Link to comment Share on other sites More sharing options...
TheRecklessEngineer Posted October 30, 2013 Share Posted October 30, 2013 Have you definately got a +12V supply to that coil? Again, I'd be very surprised if EDIS is at fault. Quote Link to comment Share on other sites More sharing options...
alanius Posted October 30, 2013 Author Share Posted October 30, 2013 Jes 12V on the coil and edis modul Quote Link to comment Share on other sites More sharing options...

alanius Posted November 10, 2013 Author Share Posted November 10, 2013 Ok so the problem is solved.Received another edis module, plugged it in and the spark was back on the plugs that didn't had one.Just need to change the plugs, drove almost 4 day's as a V6...the old EDIS smelled to burned elektronics, 99% of the time that isn't good ;-) Quote Link to comment Share on other sites More sharing options...
Bowie69 Posted November 11, 2013 Share Posted November 11, 2013 Result, very good one in the end Quote Link to comment Share on other sites More sharing options...
Hybrid_From_Hell Posted November 11, 2013 Share Posted November 11, 2013 Glad now sorted, very unusual for EDIS to fail..... where is it mounted ? Nige Quote Link to comment Share on other sites More sharing options...
alanius Posted November 11, 2013 Author Share Posted November 11, 2013 Edis module is mounted together with the ECU in a waterproof box te keep all the dust and dirt away.module is bolted with the 2 holes that are in the module. The box is mounted on the rear bulkhead and I never went that deep in the water. Quote Link to comment Share on other sites More sharing options...
