msmile Posted December 20, 2012 Share Posted December 20, 2012 Hi! I need some help here... Theres a very weak spark on the plugs and the car doesnt start. It happened suddenly, i drove the car to my friends place, and after 15mins it didnt start again. I checked the terminals for the igniter, and found 12v 5v and ground as well, which is normal i believe. I put the new igniter, but still the same... All the wires seem ok, HKS S40i plugs fitted few hundred miles ago. I never had a single missfire or any other problems with ignition or fueling. Any ideas?

Swampy442 Posted December 20, 2012 Share Posted December 20, 2012 How do you know you have a weak spark? Link to comment Share on other sites More sharing options...
msmile Posted December 20, 2012 Author Share Posted December 20, 2012 (edited) I took one plug out and put to the coil on the rocket cover, ensuring it has a ground connection, and then just tried to start the engine watching the plug Edited December 20, 2012 by msmile (see edit history) Link to comment Share on other sites More sharing options...
msmile Posted December 20, 2012 Author Share Posted December 20, 2012 Forgot to mention - i found the trouble code 14 flashing, but after reseting the ecu, it has gone, but nothing changed... Link to comment Share on other sites More sharing options...

David P Posted December 20, 2012 Share Posted December 20, 2012 (edited) The Manual gives 3 possible causes, you have tried one, so there's 2 more options. Edited December 20, 2012 by David P (see edit history) Link to comment Share on other sites More sharing options...
msmile Posted December 20, 2012 Author Share Posted December 20, 2012 I did check the harnesses and ecu, but as far as i understand, they were ok. I cant just all the parts just for testing I hope someone has the same problem before and knows whats the problem. Link to comment Share on other sites More sharing options...
Ian C Posted December 21, 2012 Share Posted December 21, 2012 I took one plug out and put to the coil on the rocket cover, ensuring it has a ground connection, and then just tried to start the engine watching the plug I'm still not sure how you know you've got a weak spark What did you actually observe from this?

msmile Posted December 21, 2012 Author Share Posted December 21, 2012 Well i think theres a weak spark, because you can barely see it even at night. What other sugestions would be? Iridium plugs? An they be gone all at the same time? Before it stalled there were no single misfire Link to comment Share on other sites More sharing options...
msmile Posted December 21, 2012 Author Share Posted December 21, 2012 Looks like i was wrong... Maybe the spark is ok. Just realised that i cant smell petrol when i take the plug after trying to start the engine. But i can hear the pump working. Dont know where to start again Link to comment Share on other sites More sharing options...

msmile Posted December 21, 2012 Author Share Posted December 21, 2012 That was a racelogic traction contol ecu. I found a battery cable loosen to the fuse for ecu. As it controls all the injectors, so they were all cut off as trc ecu was off. Simple, but spent nearly 2days on the car and now have a spare igniter Link to comment Share on other sites More sharing options...

Chris Wilson Posted December 25, 2012 Share Posted December 25, 2012 The RLTC fuse is an abortion, it really needs the fuse holder changing to a better quality one. I would suggest a blade type in a sealed holder. Link to comment Share on other sites More sharing options...
