kevz_kuzzie_kustomz Posted August 10, 2011 Author Share Posted August 10, 2011 evening all . no i have not asked on hybrids yet. i might have to sign up aye. My car is a 1984 model and i am the second nz owner. got it completly stock standard off a old man bout a year ago haha. mods iv done so far are exhaust system, external wastegate plumbed to atmosphere of course (fun job of pulling it on haha not as simple as putting one on a RB as manifolds are on the same side.) and lowering and rims. lots more to come after fixing this prob. ok next step to trying to solve my ignition problem. today i started up my car. started first pop and ran fine. i removed the plug from igniter to coil. hooked up a LED test light to earth first. 1 pin is ignition. others hav no power. then i hooked the LED to power. found one pin is always earth. the 2 others are pulsed earths when cranking. so now i kno what the igniter packs out puts are when car is working fine. then i put it all back together as normal n started her up. hmmmmmm now i want this car to fault so i can check if there are any changes to the outputs of the igniter. if all outputs are the same i can point probs to be the coil i spose. so i put it back to normal n run it for at least an hour waiting for it to cut out. but it freeekning wouldnt hahaha. id say because i am just letting it idle its not putting enough stress on the electrical components to make them fault. i dont want to keep reving it till it cuts out and upset the neighbours either haha. so i spose i mite have to get someone to follow me and test it on the road side when it faults. hardly ever does it and when it does i end up towing it home and when i get home it starts up straight away hahaha. I spoke with old owner of this car today and he told me he had encounterd the problem before. he brought it to garages that couldnt figure out the problem as everytime he brought it in it wouldnt fault hahaha. i very much think im on the right track to having it sorted its jus waiting for it to fault next so i can test out my theory. i spose i could of jus spent a whole lot of money replacing everything with new stuff (thats if i could track the parts down, geting a replacement CAS was hard enough) but i want to learn more about these old L series motors .

0R10N Posted August 10, 2011 Share Posted August 10, 2011 What is the part number on the coil you have there? Could look it up in FAST and see if it's the later revision or something from a different Nissan (possibly a VG one) Actually... are you 100% certain it's a spark issue? my DR30 also shat the fuel control module in the boot which had almost identical symptoms (leave it a while, and it would start going again), except it was fuel not spark that was being cut. I've heard of the power transistor problems too, but thankfully haven't run into them with mine yet. Quote Link to comment Share on other sites More sharing options...
kevz_kuzzie_kustomz Posted August 11, 2011 Author Share Posted August 11, 2011 definately a spark problem as i hav no spark when it faults Quote Link to comment Share on other sites More sharing options...
