ok guys

some background first... i got epa'd....

i have a s1 r33 gtst, before i went to the epa i re-installed the std turbo+ecu+injectors+air flow metre ect ect and started her up. all working fine. took it for a test drive no more then 500 metre and she just died on me(no smoke no sounds). i tried to start her again and nothing... tried again and she started fine so i drove home,

kept the car running for about 30 min with no strange signs.

next day i drove to epa (about 45min) and passed.... no more then 5 min after i left it happened again but this time she wouldnt start (tow truck home)

ok so...

-the engine cranks

-all fuses are fine

-dont get fuel pressure (fuel pump fine)

-windows dont work

-none of the dash warning light up

-turbo timer does no light up

-alarm works

-radio+lights work

any ideas would be great

Sounds like a power supply problem.

Check the connections at the battery, check the earth point in the boot, give it a clean with a file if you want to be sure.

Then have a look at the earth points on the engine block. Check out the power supply cable on the starter and the connection going to the fuse panel. Then you can start doing voltage drop tests, from the battery to the starter etc. It can even come down to a crook end crimped onto you main power lead.

Cheers

red -- you sure about this one ... if you dont get fuel pressure then the pump is not getting power .. this is controlled via the ECU ..

do the lights on the dash go on when you turn the key??? like the engine light and oil light etc come on when cranking..

mine shuts of for 1 second when turniong mine over after putting the power FC in. then come on and it starts!

the turbo timer shouldn't come on til your key turns to acc.

hey sumo

ill be checking all the conections tomorow. (but the head lights and radio work)

why wouldnt the windows work?????? or the turbo timer????

that stuff isnt connected to the ecu is it...???

i have a feeling it could be the ecu or a short somewhere along the power lead (as you stated) or both...

craved

i have a fuel press gauge so yes im sure and u can normally hear the pump when key is on acc.... but this is not happening at the moment.

the lights on the dash do not come on (key on acc) or while cranking

and turbo time doesnt come on when key is in acc possition either...

is there any way of checking if power is going into and out of the ecu???

ill be putting my pfc back in later on this week,

    • looking for some help and maybe some insight on others experience with a new LSD. R34 GT ran and drive beautifully, but always alot of grip loss due to the open R200 rear end, so I just installed a new 1.5 LSD way into the stock open R200 for a ER34. Simple. Everything seemed right. I test drove for the first time this weekend. as I started to back out the garage the first time slowly with tires straight it sounded and felt like I had a loose or half disconnected drive shaft...that was clucking around loose and shaking entire vehicle, and making it feel like the trans clutch was spontaneously slipping then grabbing very roughly while just letting out pedal slowly. I backed it out went to pull forward with the same noise, shake and slip grab feeling with hesitation, I turned the tires to back out more and then pulled ahead some same thing but worst because of added wheel resistance (which that I expected) puzzled … pulling it back in checking everything over and finding nothing wrong, I tried it the next day. same thing, couldn’t believe how it shook everything again making a terrible noise and making it feel like the trans clutch was slipping and grabbing, but I got it out of garage into the driveway, got it straight, drove forward and then reveres a few times in a straight line everything shaking , causing what felt like clutch slip and grab every time, sounded like right behind front driver tire and I could feel it in the floor board with my feet,... worst right when beginning to let clutch pedal out to engage slightly, shuttering and sounding terrible along the way…I managed to slowly get down the road, babying it the whole way, once I was rolling (out of 1st) seemed to be better and between shifts, then clutch felt closer to normal…not slip/ grab etc., but back down to any stop, straight road or turning, same thing. Made no difference if all tires were straight or if I was turning. All other gauge read out correct. with in 2 miles as planned I reached the empty parking lot and performed the break in procedure that came with lsd, essentially to drive in a figure 8 a bunch.  Did this, binding chattering, and shaking the car the whole way. I drove it back home seemed somewhat normal once I was in straight line and past 10 mph or so, and I know it will “bind” on corners and cause some tires squeal when turning especially from a stop, but when I begin to move it still causes what feels like the trans clutch to slip and jerk badly as well as shaking the entire car, and sounds terrible, that I didn’t expect. I used the fluid they supplied with LSD kit and did the breaking, planning to change fluid as they suggest after breaking, but wondering will it get smoother or less aggressive with use? maybe a 1.5 is just too aggressive for normal road driving?   I have a LSD that I put in my 71 cuda when I restored it, with amazing smooth , quite yet effective results. Different style LSD but that ones a joy to drive. maybe expecting too much from this R200?

    • Hello!  i just finished manual swaping my r34 skyline with a r33 rb20de box(RB71C)box  When the car is running it squeaks crazy loud and it was smoking from the gearbox area. The gearbox is fine it was tested. The clutch slave cylinder seems like it doesn't fully releases the clutch. I want to ask if this noise is from the throw out bearing or could it be the clutch assembly or disk att.xFliq87Gzw6kImKBVqDebXkj0fBqymk0JaYeP3_3SlM.mp4
