hey guys

i have a rb26 it has 700cc injectors power fc rb25 afms ect.. i had hks gtss turbos on it before i took the turbos off to upgrade the car was tuned and running fine not one miss ect... now ive installed twin high mount td05s and it wont start, in know it wont run perfect if if was to start but it wont start? could it be the plugs? theres no spark coming from the plugs but theres none from the coil packs either?

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

    • I have been being VERY quiet about what you're alluding to, as it is something that ticks me off... The number of cars from factory that run coil overs is HUGE! Most of them these days do... The other part that annoys me, is people saying "Well all the incabin adjustable suspension is illegal by blah blah blah"... If that's the case, then why can I buy a car brand new that can do it if, FULL STOP in cabin adjustable suspension is illegal...   Also, I could just chuck some aftermarket shocks in my car, throw the stock springs on, after my blue slip, dump my super low springs back in. Same shock and spring style setup... Hell, they could also be the same colour springs etc.     I'm voting, BlueSlipper didn't want to touch the above car for some reason. Whether it be some sort of bias against the car, the owner, them maybe having previously done dodgy shit and now they're being super careful in case they get slapped in the face by the Gumbyment again... Find a new blueslip place.   And can confirm as you had said, yes there are holy bibles of vehicle heights, and all sorts of other suspension stuff. Heck your run of the mill mechanic, and tyre shop has access to all of that stuff. It's how they do wheel alignments...
    • Funny story Heading to Sydney this morning on the HWY there was some slow traffic, so I gave it the beans and midway through my overtaking "power run" I lost all power It seems that I missed a hose clamp,  and the MAF and filter went WiFi To make this more problematic, the little tool kit that lives in the boot, is sitting in the sun room at Goulburn......LOL Luckily for me I found a bit of steel on the side of the road that could be used like a rusty and bent flat head screw driver to tighten it up enough that it got me into Sydney, it is now all tight like a tiger with the aid of a 8mm socket Note to self: Use my brain and double check stuff, and always keep that little tool kit in the car for when I have a brain fart
    • Oh, and as for everyone with their fuel economy changes, I switch between E10 and 98 in the company car. Even do when I had personal cars that could run on E10. You know what changed my fuel economy in any noticeable way? How I drove, and where I drove. Otherwise, say on full tanks of just back and forth from work only (So same trips, same sort of traffic), couldn't notice a difference that I can correlate to the type of fuel in use. In the current vehicle, that's over 42L of USABLE fuel. While 98 is all "more energy dense", it also has higher knock resistance as it takes more energy to get it to ignite too. The longer hydrocarbons, typically more tightly bound. So running the same ignition map, can also produce less power, if there isn't enough time to get it all burnt through properly, as yep, the flame propagation speed is different from lower octane fuel to higher (Higher has a lower flame propagation, due to the more tightly bound and harder to self ignite funs. This is also typically where, a vehicle that is designed purely to run on 91 (Whether it be E10 or normal 91) usually sees absolutely no real world difference in fuel economy for the normal man, woman, or dog.
    • We've got some servos around me that have 91 with E10, 91 (no E10), 95, and 98. At those stations the change from 91 E10 to 91, is typically around 8c/L.   But lets not get started on the price of fuel in Oz. It's ridiculous. All the service stations around me, bar one, the price of fuel has been over the $2 mark per litre for the cheapest, 98 being around $2.45. That one service station is a CostCo, fuel from it comes from the same refineries, and makes no pitstops, it runs great, including the 98. In fact, I've had no issues on CostCo fuel, but plenty of issues at other stations!. The CostCo fuel, was $1.65 roughly this week for 94 with E10. $1.88 for 98. Servos directly across from it, $2.10 for 91 E10, and $2.48 for 98. The part I had to laugh at? If I drive multiple HOURS away from Brisbane, say out near Nanango, or Kingaroy, or even out to Goondiwindi, the price of their fuel, is the same as what it is at the CostCo... Oh, and that BP servo at Goondiwindi is HUGE and goes through epic turnover of fuel, so it's not sitting there for weeks going to shit. And what blows me away, my mate is one of the people who drives the Fuel Tanker all around QLD, delivering to all those places. At the same company his previous role was doing the "local haul" deliveries... Same truck, same driver, same pickup point it all comes from. So you tell me, how the hell it is 60c/L CHEAPER for fuel, when nearly all else is equal, except they require a B-Double to drive half a day out of Brisbane, and half a day back, every second day, compared to the delivery that can be under 30 minutes drive from the fuel pickup point... Not to mention, go five blocks down the road, and Ampol to Ampol will vary 30c/L... And I've had this conversation with my mate... The way it's priced, is just typical, pure and utter rubbish... He also does runs from Brisbane, to all over QLD, down to Newcastle, Sydney, Nowra, Melbourne, Geelong, and even out to parts of the NT depending on the companies needs. His main stuff is all the longer distance away from home for a few days at a time, then when he's back, he loves to just pickup extra shifts wherever he can in whichever truck, hence all the weird different places.   Oh, as for getting E10 into all the fuels in Australia... It was very quickly highlighted, that we don't have enough biomass available to use to make E10 sustainably like they require, and it would dramatically cut into our, and the worlds food chain supply...   I vote we all just start running on liquid methane gas... Plenty of that just getting tapped off at tips from underground decay... (Note, this is pure just stupid commenting. I could very easily highlight the reasons its not a good idea especially on scale...)
    • Am I correct in assuming that the R35's are getting the classic skyline haircut off the odometer?  Quick search on carsales, there are 33 08 and 09 GTR's for sale, only 2 of them have more then 100,000km's on them (116,075 and 110,000 respectively).  And somehow there are about 25 for sale with around 60,000kms? Looks like the classic skyline haircut to me =/
