If your not getting any spark then you need to check why, that will be your problem.

When i first started my Silvia after rebuilding the engine it took a bit before it started and actually ran nicely as the inlet manifold had been sitting around all that time and i hadn't cleaned the injectors, (lazy i know) so i presumed that was the reason why as it could of had some stale fuel in there,

But if your not getting any spark you need to find out why first check all your connectors etc

As above, check that the crank angle sensor is working (test it out of the car to see if you can get spark). Obviously check that everything is plugged in, but start at the CAS and work your way back towards the ECU. Make sure you have fuel etc.

Yeah mate, if you're not getting spark you're never going to start the engine =P as the previous kids mentioned check the loom and connections, also check the grounding on the loom. If you have an ignitor module check that. Bust out the multimeter and check that you are getting power and signal properly to the pins back to the ecu if need be, you gotta find out why. Obviously check the ignition =P

As there's no spark from the coils it means it's not the plugs too, it's at or most likely before the coils (before if all coils aren't firing pretty much)

Good luck!

ok just quick question i pulled the coil packs out and put the spark plug in the coil and grounded the plug and no spark (not sure if stuff plug or no spark) but when cranking it if i look into the coil pack should there be spark coming from them even tho its not grounded and no plug?

The plug should be near a ground metal and when you crank it there should be spark from the plug not form the coil. If no spark , plugs can be bad and also check your coils to.

given youve done a lot of work, check the basics

check all wires and sensors, check all basic engine functions, check power, check plugs etc

check ETC, SENSOR SW CHECK on the hand controller for sensors with black names (highlighted)

after you;ve done all that, run a re-check of everything and then isolate

air, fuel, spark

if you have all 3 it should start and crank over

    • You've just discovered a really good reason to tell yourself, yes, I do need to buy an aftermarket ECU. Put the MAF in the bin. Slap in the new ECU and have a think about what turbo sounds you prefer.  Do you want a 90's style BOV wooosh? Do you want a hektik tsututututu?  Mate, can't go wrong. Just gotta get that ECU and the world is your oyster. 
    • Hi. Iam just curisou about this topic. I saw this video. It is about Greddy Type FV2. I know that BoVs are about that sound but how and when to use it? I read some topic here and from what i have understand on stock RB with MAF there will be some "problems" if you use this BoV? It vents the air in to the atmosphere and the MAF on stock car needs this air back in to the intake and not out? Or is it wrong? If so...i saw you can put some adaptor to circule air back...but does that not "loose" that sound? I saw another BoV from Turbosmart and it has two "exhaust" like ports? One is for the stock tubing for letting air back and one is for "sound" and let the air in the atmosphere? Can someone please explain? This is the Greddy one:  And this is the Turbosmart.     THANK YOU!! EDIT: So i read about this topic some more and i if i understand that correctly: That Greddy can function either like BoV or 100% Bypass valve? And that Turbosmart is what they called hybrid so you can adjust what and how many air can be vented out or back in? Is this right? THX!
    • That dirty voltage drop is the culprit I suspect 
    • i cant get them all in 1 screenshot unfortunately as i just dont know how to move things around tbh, but they are all from the same log and the line crosses at the same point for all of them
    • It's about time I start work on my sun tan. So I knocked up a few parts that will all combine together to become my new power steering reservoir. Now just to produce an abundance of UV and IR rays while melting a heap of bits of alu to become one... Well, that's after I put one more hole in it for the return line to plumb to. It likely won't be this weekend, as Sunday I'm meant to be in doing some last minute stuff to the AMG race car, and the weekend after will be filled with non my Skyline stuff, followed by Bathurst 6 hour. So I don't expect to get to melt metal for at least 3 weeks.   I also managed to stuff up and start cutting the hole for the res to pump pipe on the wrong side of the line... It means instead of the lines being nice and tight against the inner guard, they'll be out off the guard.    The size of it means I should end up with about 1.8L of power steering fluid, and still have space for another half a litre before it reaches the overflow/breather. This is wayyyyyyy more capacity than factory, which should help keep Powersteer oil temps lower, and the design hopefully allows it to prevent any aerated oil being able to makes its way down to the bottom as it'll have a couple of baffles and some hopeful trickery to force air bubbles away from the bottom.
