HELP my RB20 died on me

[a1cpunker]

i've searched but couldn't find the answer to my problem so i'm hoping somene can help or point me in the right direction.

I was out driving the other day and suddenly the car studder, backfired, and died. she won't start back up after that.

she would crank but won't turn over. There's a thud sound when the she is cranking.

I've checked:MAF = goodno boost leaksfuel pump sound like it's pumping ok

Thank you ahead of time.

coils got too hott and died out yo!

if you cant help, dont leave a smartass comment.

first things first, check for spark, and fuel. remove a coilpack, install a jumper plug wire, ground it, and crank the engine. see if there is a spark.

if there is a spark, check your spark plugs, see if they are wet or smell like gas. if they do NOT smell like gas, unbolt your CAS from the front of the engine, turn the key to "run" and spin the CAS. you should hear the injectors click as you turn it. if they DONT you may have a bad CAS.

im willing to bet something like your CAS went out, or the igniter.

let us know what happens.

it wasn't a smart *** comment!!!!!!!!!

it was help meaning i think his coils took a dump.

[Yellow4g63]

Did you change the timing belt when you did the swap? maybe the belt broke?

all 6 at once?

....

[s14 2510's]

Yup those 6 were on a union. There on strike!Or Mr igniter probly got tired if the union BS and said piece out. Who knows.Start by checking spark. Then fuel.

yea kamin is right...all 6 won't go at once...more than likely the igniter or the CAS..my buddys skyline went from running good to not running at all cause of a bad igniter

thank you for your respond.

what do you mean by using a jumper spark wire? i'm kind of new at this and still trying to learn.

i took the coils out and put another plug in and try to crank it and i see no sparks. i don't know if that is the right way to check it.

i'll do the rest of the checks after work....military scheduling sucks

[shally2186]

when i took mine out and cranked it i got a whole bunch of sparks (my buddy was holding them and he freaked out lol)...not really sure tho..just listen to kamin (he knows his ****)

haha. yea i didn't get any sparks.

yup i'm going to do the rest of the things that he said to do after work.

and thank you everyone for y'all help. i'll post up the result asap.

[a1cpunker]

Did you change the timing belt when you did the swap? maybe the belt broke?

yup changed the timing belt with greddy ones.

anyone have an ignitor chip for sale?

[kumasan616]

try and clean the brass contacts on the ignitor before you buy another one... they can get corroded if nto properly covered in grease

[Cjmartz2k]

Look up how to refurb coil packs on skylinesaustralia.com ---they have a pretty good guide in the DYI section.

Is Seymor-J your first base, or did you bring that motor back with you from accross the pond?

yup first base. so far it's treating me pretty good.

are you here at SJ too?

back on topic: thanks for all the reply i'll try and do the cleaning of the ignitor chip. i ordered the splitfire coilpack set. i guess i might as well change out all the coilpack while i'm at it.

can y'all point me in the right direction? i searched the aussy forums and couldn't find the coil packs and ignitor chip refurbs procedure.

[craz4240]

Also for ignitor check out Carl H's how to on 300zx Ignitor Chip retrofit.

[mott6904]

Before go and replace the coils or ignitor, find a factory service manual if you dont have one already and check for power and ground and all the other signals it is supposed to have. Its alot cheaper then saying i think this is bad and it is something else

thank you for your input. well i tested the coilpacks, it came out normal. tested the CAS and that came out normal also. TPS is normal. i tried to test the ignitor chip but didn't understand the FSM, so can someone tell me how i can test it? and how can i test the ECU to see if it's still operating like it should?

thank you everyone for yours iinput.

[mott6904]

To test the ignitor i believe you need to check for power, ground and your switching signals and the same coming out. Can you start the car on starting fluid? Have you checked the timing belt to make sure it didnt slip? Have you checked for power and switching ground at the injector?

i haven't tried starting fluid yet...but i don't get any sparks so i don't think it'll start anyways. yea i checked the timing belt and she's still there. injectors spray when i turn the CAS. going to try the 300zx ignitor conversion. i have a feeling my ignitor is out of commissioned...

[mott6904]

My bad i must have over looked the part where you dont have spark. I would check the three pin connector for the coils and ignitor. IRC the white is power and then the small black is the cylinder1 timing and then the bigger black wire is the ground. The connector that plugs into the ignitor are just ground signals from the computer. i believe you should be able to ground out the wire the goes to the ignitor and then see if you have a signal coming out of it. Do that for each wire and if it is good then you will have a ground signal coming out the other side. Someone correct me if im wrong, but that sounds correct

thank you. i'll try this first thing in the morning.

Did you solve this? I'm in Japan, not NC BTW.

Take off the coil, pop off the little boot on the bottom. Pull the spring out while spinning it in a counter clock fashion. Take a dremmel with a pointy 'ish stone bit and remove all the black "varnish" that builds up in there. Should look shiny and brass again. I did that to mine and the stopped missing and ran a crap ton better.

Splitfires are crap. The only difference for most is they are new. I'm making 500rwhp at 1.8 bar on stock coils.

[QUOTE=Cjmartz2k] I'm in Japan, not NC BTW.

in japan huh,does that mean u can get us hook ups on parts??..lol

[Cjmartz2k]

Sure, but I'm not trying to box up and ship motors and stuff. If you need some small hard to find/easy to ship stuff, we can work something out. Junkyards here are overflowing with junked skylines. Not so much with the GTR's, but anything else is easy.

[mott6904]

Sorry to steal the thread but can you get some nismo bolts. I need the 12mm bolt with a 13mm shank used to bolt a s13 ring gear to a s15 diff?

[a1cpunker]

yes sir. got her started this morning. sanded all the grounding points, sanded the coil packs, and installed a z32 ignitor that i got from a friend. she still need to be tune though. i didn't mark the CAS when i took it off....stupid me.

thank you everyone for yours help.

so can you spot a pair of bricks silvia headlights for an fellow airman?

[Cjmartz2k]

Are you wanting the 3 projector ones? I know where some of those are. The guy usually wants 5000Y a headlight, so around $100 plus shipping for the set.
