Thanks for help mate, thats what i will need to do but trying to find ther right person is as hard as finding the problem itself. lol Paul

Thanks for you input the coil packs were brand new and the brand were Supa Spark, if i changed over to splitfires do you think they would overcome the problem? I agree that second hand would be a wast of time. Tahnks Paul

Hi every one, Thanks for your quick replies and feedback i just want to say that i will take every suggestion very seriously and hopfully find the problem. I made a mistake with name in my previous message about where i am thinking of taking the car, the proper name is "Advanced Jap Auto Imports" in tottenham vic. so please let me know what you think. As for the coil packs they were all brand new and they are the Supa Spark brand. Thanks Paul

Hi every body,i am new to this forum and from what i read over the past weeks i am sure some one will be able to assist me. I am on here on behalf of my son and i am hoping you might be able to help me. He bought a skyline r33 with the rb 25det series 2 engine about 18 months ago, every thing was going fine till about 6months ago when he started to get a missfire. We found that the original coil packs were shorting out. I bought a new set of super spark coil packs and had the mechanic replace them. the car ran fine for a week when all of a sudden it started to missfire again and i thought it couldn't possibly be a ciol pack problem so this time i took to a high performace tune up specialist specilizing in skylines. After putting on the dyno and checking the entire system he found one of the new coil packs was not firing and we replaced it with a second hand nissan one and again every thing was ok. The faulty pack was replaced under warranty and we took out the second hand coil pack and replaced it with the new super spark pack. Two monthes down the road and would you believe it the same problem again, this time we took to a high performance specilist in melbourne who found 2 coil packs not firing. Had to pay for a genuine nissan coil pack just to get the car on the road, the car was once again running fine and after complaining to super spark supliers had the whole set replaced under warranty. I have now replaced all 6 coil packs again and 1 month later one of them has already failed my son's car is stock standard apart from the front mount intercooler it has been checked by 3 different specialists and they have found no other problems, the coil pack loom is fine and has checked and it runs at standard boost. The thing is the problem has deffenetly been the coil packs but i realy can't see how all these coil packs can be faulty and fail in such a short time. Is there anything that could cause the coil packs to fail? His ECU is standard as far as we know and the mechanics do not seem to think it has been tampered with. Please help if you can. I can only tell you what the mechanics told me so i don't know how compitent they are as i think that there has to be something causing the coils to die, so fer it has been cylinders 1-2 and 6. I am thinking of taking to a place called "Just Jap Auto Imports". Does anyone know of a good place to take the car? I have been told that there could be an electrical problem can some one please shed some light on the subject ? I am a pensioner and can't afford paying when they don't find the fault and just tell me that the coils are faulty. I don't mind paying if they find the problem and not take the easy way out and surely we can't be so unlucky to cop all these faulty coils. I now this is a long thred for a new commer and i am sorry to be a bother but please can some one help. Thanks Paul

Hi Rick, regarding the problem with the coils dieing on my sons r33 gtst the required testing is above my knowledge and i found a place in melbourne called "Advanced Jap Auto Imports", I was wondering if you have heard of them seeming you are in the trade and if they know what they are doing? I am thinkig of taking the car there to see if they can find the problem. Even if anyone else reading this post has had any dealings with them please tell me what you think of their work. I am pensioner so money is very tight, i don't mind paying as long as the problem is fixed, as i explained the other 2 places i took it they just blamed the coil packs and you do not have to be a mechanic to know that there has to be more to it. Thanks Paul

Thanks mate, my son is comming up to lakes entrance with his car this weekend and i will do what i can. i should be able to Clean the contacts but all the other elericale suggestions would have to be checked by a pro. Thanks for your input. If someone could suggest a good place to take the car (in Melbourne)and have this problem checked i would appreciate it Thanks Paul

Thanks HeyHey, yes i will have to start looking at all the other possible causes, i will write down all the suggestions that you and anyone else is kind enouth to give me and see if i can fix the problem. I am open to all suggestions so if anyone else wants to add any advise i would greatly appreciate it. Thanks to all on this forum for your help and if i do find the problem i will let you know, but in the mean time please keep the ideas comming in. Paul

Hi Rick, The first time it happened to the original nissan coils the mehanic changed all of them because he said that it would be the best option so i do not know which cylinder number coil was faulty. Since i have been tracking the problem it has been the coils on cylinder 1-2 and 6 so i am at a loss. have you any suggestions which might leed me in the right direction? I have a very good friend who is an auto electrician but they do not have a dyno and do not have experiance with these cars. Thanks Paul

Hi Rick, thanks for your quick reply,all i know is that when they found the faulty coil pack they checked the loom plug that connects to the coil pack with a test light to make sure that there is power to it and they also try different coils in place of the faulty one and if they work then they try the faulty coil in place of one of the other coils and if they do not get a spark then they blame the coil pack. I am not upto date on these cars but i have worked on older cars all my life and rebuilt a vc valiant from bottom up so i do know a little about cars and i find it very hard to believe that all these coil packs are faulty and agree with you that there is another issue. What i do not understand is that if there is a problem some where else why does the car run fine for a couple of months after replacing the suspect coil? can the problems you have mentioned cause the coils to fail? Can you recommend somewhere around melbourne where i can take the car and have them check for the possible cause? i would like to take it to someone who knows what there doing. I cant afford to be replacing coil packs every 2 months. Again thanks for your help and i look forward to you reply
