    Help: Fuel Issue (I think)

    in Nissan RB Forum

    Posted

    Ok. first off, your original post you stated the car is not turning over. This would lead me back to a battery/terminal issue, not fuel related. 

     

    Lets get things straight, when you turn the key to start it, does it turn over and do so strongly?

     

    The way the stock ECU works is that when you first turn the key to the "ON" position, it runs the pump for 2-3 seconds. It won't do it again unless you turn the key to off for like 15 seconds (try to go back to "on" too soon and it won't prime the pump again). Also, it's very unlikely you flooded the engine on an EFI engine provided you do have spark. If you do in fact have spark, then when your pump starts working, it would fire right up. Also, pretty unlikely that your plugs fouled enough to stop it from starting. Yes fouled plugs can cause misfires under higher loads, but the spark required to start the engine isn't that much.

     

    But get back to us on the engine turning over first and lets work from there.

     

    It's turning over and running a nistune modified z31 board. Turned out to be fouled plugs. Replaced those and it fired right up.

     

    I guess the autozone fuel pressure gauge was bad which is weird and cost me an extra fuel pump. So I have a perfectly good Walbro inline 255 if anyone's itching for one. The larger issue turns out is that brand new plugs got fouled after 4K miles. Pretty sure the valve seals are bad on the RB. It answer the question on why it stopped running immediately after I overfilled the oil, explains the white smoke and the oil shooting out the tail pipe under hard acceleration (newly discovered). Fun. 

     

    Anyone bored and want to help rebuild an rb in Denver? I was going to do a stock internal upgrade at some point so...while I'm in there...

    Ah the line "I got a fuel pressure regulator from autozone" made me rethink what I read. Looks like you meant fuel pressure gauge not regulator.

     

    What does confirm power mean? That you ran a new line? Or just that you checked the power with the multimeter?

     

    Well seems like you may be on your way to figuring it out. Good on ya!

    oh...I missed that. Definitely gauge not regulator. Confirmed power at the pump with the multimeter. Swapped out the fuel pump today and have pressure again but still not firing. The plugs are pretty dirty. So, going to swap those out tomorrow.

    Oh I misread that. Did you plumb in two fuel pressure regulators now? You shouldn't have two pressure regulators in series if that is what you did.

     

    Short of an injector sticking open I don't think you would flood your engine. Granted that could explain where the fuel is going if the pump is running and you have no leaks and don't build any pressure until suddenly.

    Nope...just one regulator.

    I've got an rb25det series 1 swapped into my 280z. I swapped in the motor, checked compressions and installed the fuel delivery among other things but wasn't comfortable with the turbo install, wiring and tune. So, I had HoustonZ do that work when I still lived in Houston. The car has run amazing for the last year...even on a high-speed road rally and a bunch of aggressive twisty driving since I've moved to Denver. 

     

    Last weekend I pulled the car out of the garage to do some work on the garage itself. When I went to move the car back in it fired up quickly as it always has it died about 5 second in and hasn't started since.

     

    This is my least capable area on the vehicle so I'm doing the youtube/home mechanic approach to troubleshooting with no success on identifying the problem:

    • I'm getting spark. I pulled cylinder #1 plug and watch for the spark, check.
    • When you turn on the key to on, the fuel pump sounds like it kicks on, check. 
    • When you attempt to crank it, it won't turn over and I hear a click, click, click noise from the pump area. After that I smell fuel towards the rear of the car. Not sure if that was always the case on start. 
    • I got a fuel pressure regulator from autozone, and tested the fuel pressure at the fuel rail (opposite end from the regulator) and no pressure. It's a stock Rb rail. Am I supposed to have pressure on attempted crank? If so, I'm not getting any. 
    • If I just hold the rubber fuel lines under attempted crank there's not a consistent pressure on the line...more of a pulsing feeling. 
    • I pulled out the multimeter to check the fuel pump- red wire on the positive and black on the frame 0.0 V with the key turned to the on position. Does that mean the pump's bad?
    • Next up is to unflood the engine just to make sure but that doesn't seem right and check the voltage at the pump with someone cranking. 

    Seems like a bad fuel pump but it's new with 4K miles on it. So, odd. Anything else you guys would recommend checking?

    Sourcing custom driveshaft?

    in Nissan RB Forum

    Posted

    When I put together my build specs about 9 months ago I made note of a $300 custom steel driveshaft that someone recommended. I cannot find the bookmark for that company and searching has turned up nothing so far.

     

    I'm aware of the McKinney and Raw Brokerage options but they're more expensive.

     

    What are you guys using for your driveshafts?

    15x10.5j Wats with s12+8 caliper fitment issue

    in Brakes, Wheels, Suspension and Chassis

    Posted

    Need some help on a fitment issue with my 15x10.5j Wats with s12+8 caliper fitment issue. The inner edge of the wheels are preventing the wheels from being bolted on flush and ultimately the calipers are at fault.

     

    I'm assuming machining calipers is not a good idea. Is that also true for the info de of the week?

     

    I'd prefer to avoid any machining if possible. Any insights into the width of the s12w calipers (or other setups) and its ability to sit behind these wheels without any issue?

    Would love some feedback on the JPN garage wide flares.

     

    The fronts that arrived fit fine. The rears however are too wide at the opening by at least two inches. I contacted JPN and the response was bend them. And they were made that way so people could put wider wheels (which doesn't make sense). And further he checked with the group that made them and they indicated that's how they are and no one has ever complained.

     

    Am I losing my mind or missing something with these?
