ok. first check ur spark. and check the fuel flow. if you dont know how to check your spark ask some body who know it to do it for you. there are may way to check the spark.

if you got spark and fuel flow is ok. i may ask you to check your CAT. block cat caused not to start the car.

just one more thing, check your CAS bolts are loose. some times they may loosen. let me know how you go.

where you locate...?

yeah i no how to check for spark and fuel

gona check it out 2mrw..

and for cas bolts, already checked that...

ive checked spark plugs and they look good.

ive also checked fuses, and ther all fine too...

but a few ppl are tellin me it could be cas, fuel pump, ecu and earths..

how often do cas just become faulty? lol

so far its lookin like that..

hmm yeah mite check my cat.. but i hav aftermarket turbo-back and dump and exhaust..but still running same cat,, lol

Lol @ cat causing the car not to start, that's a pretty far out idea lol don't think that'll ever happen...

Bro answer our question properly, is the engine cranking over? You said it is then you say it's like you've got a flat battery? Huh?

CASs do go from time to time, old RB30s suffer from that badly, infact it's not a rarity in any RB...

Try uploading a video of it trying to start, cos from what you've described, it could be almost anything. And some info on the car would be nice lol, we can't tell you anything unless you give us details of the car. What mods, auto/manual, kms, aftermarket ecu or stock etc...

he said car stall while he driving. car crank over and no start Situation you must check cat. block cat wont start the car. it happen very hardly. but in this case more than 50% chace on cat. BLOCK CAT WANT START THE CAR. thats a true logic mate.

mate without doing basics dont mess your prob. just think abt this. for start the car you need, FUEL/AIR/COMPRESSION/SPARK and EXHAUST[CAT] just check one at a time.

without these 5 elements you wont start the car.

Bro, I've never heard of a blocked cat being the cause of a car not starting, on any car. It'd take a heap more than just a blown turbine wheel to black a cat significantly, that's the only thing I can think of that would block the cat up, there's simply nothing flowing through the engine to cause such a blockage.

That's why I asked for more info on the car. If he has a stock turbo there's a chance the turbine wheel has failed and some sorta ceramic dust has made it's way into the engine, or even the compressor wheel has sent shards into the engine, and he's lost compression in one or more cylinders.

IMO that's much more of a logical cause compared to a 'blocked cat'

And also, might wanna clean up your typing bro, your English is terrible. My brain hurts from trying to understand your posts dood :cool:

suss it out, fuel pump relay wiring..

in the boot der is a relay.. switch 3 to 5 and a coil from 1 to 2.

the switch is working fine..

but my signal wiring i believe from the ecu, which is 1 or 2 is not working..

so for a temporarily fix i installed a on/off toggle switch from 3 to 5 were the relay would be..

and car starts fine...

really random.. :D

      Haha thanks Lith,  So it's currently working quite well and the torque reduction is setup and working phenomenal. It also got a custom torque convertor from All Fast in WA. Stall speed somewhere around 5500rpm unlocked but still with the lockup. The car went back onto the dyno after a 3yr hiatus (even with the dbw, and other mods completed in this time) managed to make ~515kw at all 4 hubs. Sean setup the Torque reduction which now sounds awesome and working well. We setup adjustable torque controlled launch control aswell.  Man what a feature. Especially when drag racing on street tyres I Managed to get out to the drags late last year and tick a huge bucket list item off of running mine and the cars first 9. Car went a 9.98 @142 Still had the young fellas car seat in the back aswell.  This was on 255/40/17 Nankang AR-1.  Currently the Turbolamik is still completing it's own torque calcs and managing shift times from there. Unfortunately emtrons can export is still a little restrictive to export the ecu calculated torque just yet but I have recently been suggested a work around that I just haven't had a chance to trial yet.

      Yeah its bad eh. Ey! Watch your mouth. Yep, spot on. The rear's are always gone too though from brake checking. I had them perilously close to a tree that we had taken down. I think the tree peeps may have taken it. Either for a trophy, or accidentally.

      f**kin' yikes! That insulation is the shittest stuff I have ever seen. You need to do an insurance job on that f**ker, pronto. WRT to the washer cover, I would have said that there'd have to be some at a wrecker, then remembered that it's a BMW, and reasoned that every single wrecked one would have been tailgating and so the front end would be trashed.
