Just blinked out the codes using the instructions in this link: http://www.gtr.co.uk/forum/123312-reading-ecu-fault-codes.html

5 long blinks, 5 fast blinks: No Malfunction

Time to turn my focus to the fuel system?

 

Am I not able to edit posts after a certain period of time?
 

At any rate, I will be testing fuel pressure at at the rail tonight or tomorrow, how much pressure should I see? 3 kg/cm2 (42psi)?

Edited by planrforrobert

Stock FP readings should be:

@ ignition switch ON:   approx 3.0 kg/cm2

@ Engine idling:   approx 2.5 kg/cm2

@ idling, disconnect vacuum hose at FPR:   approx 3.0 kg/cm2

A known good CAS landed at the shop today, installed it correctly...no change.  Will still crank and crank but no start.  Will be checking fuel pressure as well as testing to see if I have spark going to the coil packs tomorrow night.

So, progress!

Pushed the car into the shop tonight and was set on confirming I had spark and fuel. Started with fuel. Pulled feed line off fuel rail...it's dry. Did some testing of the pump wiring and everything pointed to the fuel pump being bad. To confirm the wiring wasn't the issue we pulled the pump out:

Used a power probe to try and run the pump out of the car, it's dead. I'll get a new pump on order and (hopefully) finally get to enjoy my car.

So that's how a properly-fed RB should run, haha.


New pump and tank gasket install was a breeze and the car fired up first try. It's like driving a brand new 25-year old car.  Throttle response is there and it pulls pulls pulls.  Thanks all for the help/insight suggestions!

Good to hear, mine is going they similar stage I started with the coil pack and did plugs too but not really much change, what kind of pump you get? And how much was it ?


I went with this pump:

Any Walbro 255 or similar pump will work, and wiring is very straightforward. I am by no means a savvy mechanic, but install took me about 45 minutes (and that included cleaning surface rust off the sending unit). Make sure to replace the tank seal if you're in there.

    • Forgot to include this but this is the mid section of my steering rack that looks like it has a thread/can be turned with that notch mentioned in the post:
    • Hey everyone, Wanted to pick some brains about this issue I'm having with rebuilding my 33 rack (PN is 49001-19U05). All of the tutorials/videos I've seen online are either R34 or S Chassis racks which seem to be pretty straightforward to disassemble but this process doesnt carry over to my rack. Few of the key differences that I've noted The pinion shaft on the other racks bolt on with 3 torx bolts: Whereas my rack bolts on with 2 allen head bolts: These changes are pretty inconsequential but the main difference is how you pull the actual rack out of the housing. The other skyline/s chassis racks can be taken out by tapping the rack out of the body with a socket and it just slides right out. I'm unable to do that with my rack because there's a hard stop at the end that doesn't let the seal/shaft be tapped out. Can also see a difference in the other end of the rack where mine has a notch that looks like you're able to use a big wrench to unthread 2 halves of the rack whereas the other racks are just kinda set in with a punch. My rack: Other racks: TLDR; Wanted to know if anyone has rebuilt this specific model of steering rack for the R33 and if there were any steps to getting it done easier or if I should just give this to a professional to get done. Sorry if this post is a bit messy, first one I've done.
    • I would just put EBC back on the "I would not use their stuff" pile and move on.
    • Can I suggest you try EBC directly again and link them to as many competitor catalogues as you can to show their listing is incorrect, eg https://dba.com.au/product/front-4000-series-hd-brake-rotor-dba42304/ If you have access to an R33 GTST VIN and your VIN, you could also use a Nissan Parts lookup like Amayama to show them the part number is different between 33 GTST and 34 GTT which may get their attention
    • So i got reply from EBC and they just this site where you can clearly see those 296mm fronts on R34 GTT. I send them photos and "quotes" that 296mm are not for 34 GTT and they are too small. But it will be very hard to return them cuz nobody here knows 100% and they just copy those EBC catalogue :-D https://ebcbrakesdirect.com/automotive/nissan/skyline-r34
