R33 Not Cranking...

[driftin_out]

hey i took my skyline for a drive 2nite, got about 5-10mins away from my place. was at the lights took off and it felt like i didnt have power..

was weird.. den all off sudden nothin and i managed to get to the side of the road and it cut out..

wasnt on boost or anythin and car was still warming up lol

nothin seems to be leaking, no cooler hoses hav come off, and battery seems perfect coz its like 3months old...

so im not sure any idea?

timing belt/crank angle????

[jrm]

Can you hear the fuel pump prime? Is it turning over and just not starting or what? More of a description about what it's doing when you attempt to start it would be useful. Could be almost anything.

can hear fuel pump priming...

pump is a walbro fuel pump put in over a year ago, and shes been fine ever since...

[koduRB25det]

is your engine cranks...?

[driftin_out]

yeah its cranking... sorry i worded that wrong..

like its trying to start, but wont..jst lik if u had a flat.. but its not, and just does the same thing...

im gona check t/belt/cam angle and fuses today...

hopefully its one of them...

anyother ideas?

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...?

[driftin_out]

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...

yeah its cranking over..lol

im plugging in a obd reader after work 2day, hopefully that mit narrow it down...

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

umm na i have an hiflow turbo with new core built by hypergear, and shes been sweet...

no problems der...

ok bro. you win. thanks for remind my english is terrible. i just try to share my experience with him.

but i have seen some cars with block cat, they never start. people fix them without change the cat.

hey dis mite be a stupid question but ive i tried starting my car again dis mornin.. it cranks over, adn did fire up once but stalled/cut out straight away...

umm but i one thing i did notice.. i cant hear my fuel pump priming...

this is my question..lol would u still hear ur fuel pump priming after trying to start it several times/alot of times??? lol

or yea.. :S

[driftin_out]

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..

lol
