bluecoup Posted August 15, 2010 Share Posted August 15, 2010 driving out for dinner the other night (friday 13th should have known better) took foot off acc to slow for roundabout the mwl came up and the orange engine light for a brief period about 3 seconds then went out, no cough or splutter, pulled fine afterwards having done the self dia its thrown up a code 14 ignition signal searched and found 3 other posts with this, the question is the coil pack/clips have not been touched since i owned the car is this something that can just break down and cause a bad connection ? car has been fine to drive since Quote Link to comment Share on other sites More sharing options...
Hoppy Posted August 15, 2010 Share Posted August 15, 2010 Both the coil packs + clips can break down over time. Apparently once the coil packs start breaking down, they deteriorate pretty quickly after that. The coil pack clips get brittle over time, from heat exposure. and basically fall apart. Have a visual check to see what condition your clips are in. When i replaced mine, a few of the old ones fell apart in my hand. Quote Link to comment Share on other sites More sharing options...
hodge Posted August 15, 2010 Share Posted August 15, 2010 Reset the ECU and it will probs sort itself out. If not take the plug cover off again wiggle the coil pack connectors and reset ECU again. If this doesn't work it's new connectors I'm afraid. Very easy to fit though. Quote Link to comment Share on other sites More sharing options...
bluecoup Posted August 15, 2010 Author Share Posted August 15, 2010 this is not something that has been disturbed ever since i had the car i'll just order some new coil pack clips and change them anyway, cars a 93/94 so they are going to be old, unless former owner has changed them, soopdog ??? you changed them ??? just worrying when lights come on Quote Link to comment Share on other sites More sharing options...
Hoppy Posted August 15, 2010 Share Posted August 15, 2010 If they have'nt been changed already, i would say they will need changing. But try resetting the ecu first, as hodge said. May save you a few quid Quote Link to comment Share on other sites More sharing options...
bluecoup Posted August 22, 2010 Author Share Posted August 22, 2010 coil pack clips changed took all of 1/2 hour tops, (cheaper from mr manley than local toyota garage as normal) took battery off to reset ecu while i was doing it, all started fine but stopping at the first junction about 3/4 mile on test drive after the engine just died, started fine straight after came home checked for code and found none, has been out for a spirted drive since and alls good atm so i'm putting the die down to the ecu relearning ?????

bluecoup Posted August 27, 2010 Author Share Posted August 27, 2010 this has now developed into a starting issue took it for a mot last week and stopped at shop to grab a paper on the way, after coming out the car took an age to start, turning over but not firing, after about 10 attempts she started all was fine passed mot, then had the stall at a juinction as in last post, went to pick the girlfriend up from train station last night and while i was sitting warming it up the revs dropped right off like it was going to die then shot up to1800rpm so i switched it off and restarted and all was fine, used it to travel to hers tonight and all was good, tried to leave to come home, sat warming it up and it died and will not restart, the fuel pump is priming up before attempting to start, the engine is turning over as normal, seems to be trying to start but just not catching, typical on a bank holiday weekend, i'm working sat, sun and mon so not going to get much chance to look but some ideas on what to check next ????????? have searched and can't find this in other posts Quote Link to comment Share on other sites More sharing options...
bluecoup Posted August 29, 2010 Author Share Posted August 29, 2010 update checked codes and the code 14 is back and it started tonight grrr Quote Link to comment Share on other sites More sharing options...
Ian C Posted August 30, 2010 Share Posted August 30, 2010 Do you get a misfire at any point while driving? If so, roughyl what revs/speed/boost/throttle opening etc? Is the idle low and erratic? Does the engine struggle more when warmed up but seems fine on cold start? Quote Link to comment Share on other sites More sharing options...
bluecoup Posted August 30, 2010 Author Share Posted August 30, 2010 Hi ian. Nope none of that. If it starts its fine pulls as normal. No misfires. Idle seems normal if a very little ruff. Off tomorrow. So going to pull the coil packs and change the plugs. As they not been done since i got it off brian. I found the fault check list on the oz forum so going to try and go though that too. But at the mo its a intermitant problem. A faith busting problem. Just don't trust it to start if i go anywhere now. Quote Link to comment Share on other sites More sharing options...
bluecoup Posted August 30, 2010 Author Share Posted August 30, 2010 From what i can see if the ign signal either to or from the ignitor or coil packs stops the ecu will cut all fuel. So you can't even run on 4 or 5 cylinders ? Quote Link to comment Share on other sites More sharing options...
bluecoup Posted August 31, 2010 Author Share Posted August 31, 2010 All the plugs changed and nothing too out of order found 2 coil packs have different colour rubbers on so guess they been changed at some point. Some of the packs have small hair line cracks around the mounting screws. And all the resistance and the packs is the same. Quote Link to comment Share on other sites More sharing options...
bluecoup Posted September 3, 2010 Author Share Posted September 3, 2010 Used it this morning to get to work and drove ok. But when i pulled up at work its ticking over slightly rough and hunting a bit only maybe 25-50 rpm if that much ???? Quote Link to comment Share on other sites More sharing options...
Ian C Posted September 3, 2010 Share Posted September 3, 2010 From what i can see if the ign signal either to or from the ignitor or coil packs stops the ecu will cut all fuel. So you can't even run on 4 or 5 cylinders ? It has to miss I think 7 consecutive ignition events in a row, which is quite a serious misfire. I assure you it will miss beats and carry on driving even on 5 cylinders. Heck I've seen one run on 2 before, although it made my mechanical sympathy bone Hairline cracks around the mounting points on the coils is normal, a bit of overtightening in the past. It's only the housing. Bit of a nightmare to diagnose this one, if it was broken all the time it'd be much easier It kind of sounds like it's suddenly flooding the engine. Next time it stalls, try smoothly lowering the accelerator all the way to the floor as you're turning it over - see if that gets the blighter running.
