take the fuel inlet hose off the engine. turn the car on and see if fuel comes out. also how sure are you there is fuel in the car. i work for racv and you would be supprised by the amount of times we have gone out to a car that the customer thought the fuel pump had died and.the swear they only.just put fuel in it only to get it back to the shop, pull out the pump and find an empty tank. next thing would be to check you afm. im sure someone on here could provide you with the voltages at the plug or if you know some with the same car see if you can borrow it

sorry for the lack of info

soooooo got some tools and done some basic tests..

fuel ok

fuel pressure ok

injector pulse ok

spark ok

even got the injectors flowed and tested just to make sure the wernt blocked

checked to see if the cat had failed and was blocking

problem is still occuring which leads me to belive its an electical problem

any ideas??

if it was the maf it would still run with a lilimt of 2500rpm becoz its in safty mode??

Unplug the afm and start the car. Doubt it's the problem though.

Get a stand alone ecu.

None of this piggy back bs

bingo.

So, the usual advice. Do some research on who are the tuners in your area (you dont want to drive 2hrs + just to drop a car off for tuning of if any troubleshooting is required afterwards) and then work out who is the best and what is their prefferred platform. Of course cost is an issue but you usually get what you pay for and a bad tune = the need for a new motor = prob not worth skimping $200 for the cheaper tuner... In a similar vein, avoid Mine's tuned ECU's. not going into why here.

General consensus is that PowerFC or Z32+nistune is the way to go. Take into account whether having an aftermarket computer puts you in easy defect territory too (if so- nistune)

Hi All,

I'm a noob so I'm not sure if I'm on the right thread or not, but here goes..

Last night I did the mod where you ground out the boost solenoid on an R33GTSt.

Well I read the entire thread on that before attempting it, & then did it as specified.

When I went to test it on my way to work this morning it would not rev over 2500rpm, just kept coughing until i dropped the revs below 2500.

I freaked out (i only just got the car), & put it back to standard, but it still wont rev over 2500rpm..

Have I broken something? Can I fix this?

So far I have reset the ECU as specified (disconnect batt & pump brakes)

I hot wired the solenoid to see if it works (it does)

& I tried running the car with the solenoid grounded & ungrounded.

Still only 2500 rpm..

Please HELP!!!

    • LOL.... a good amount of people (not all) on that continent seem to know everything and like to measure things in bananas, football fields, statue of liberties instead of the metric system lol.
    • I assume the modules are similar enough, so if you've had no issues I don't see why I would. I have tried to find a wiring diagram for the FPCM / fuel pump circuit, but I can't find it anywhere. Otherwise, I would just do some wire cutting and joining at the FPCM and give the 12 V supplied to the FPCM directly to the pump instead. If you know anyone that could help with wiring diagrams, I'd be very happy  
    • If it dies, then bypass. The task isn't difficult. I have one running on a standard R32 FPCM. That's after nearly 20 years of it running an 040, which pull substantially more current than the Walbro. They're not the same module, but I'd hope it indicates that the R33 one should be man enough for the job. I think people kill them when putting proper sized pumps on them, not these little toy pumps we're talking about here.
    • Silicone spray won't hurt anything. And if it does, that's an opportunity to put some solid steel spherical bushings in, so you can really learn what suspension noise sounds like, If you're going to try it, just spray one bush at a time, so you can work out which one is actually noisy. My best guess is that if the noise started only since putting the coilovers in, then it is just noise being transmitted up through the top mounts of the struts, and not necessarily "new" noise from bushes. But it's almost impossible to know.
    • Are you saying the 34 is SUV height, and not that we're talking about an SUV here? (because if we're talking about an SUV, you don't fix them. You just replace them when something breaks. Not worth establishing sufficient emotional connection with an SUV to warrant doing any work on one). I wouldn't jack my car up on a short little loop of 10mm steel rod poking out through a hole in the bumper bar, front or rear end. I realise that we're probably not talking about that type of loop at the front, being the one under/behind the bar on a Skyline.... but even for that one, trying to jack up on what amounts to a thin piece of steel, designed purely for withstanding a horizontal tension force, not a vertical compressive force (and so would be prone to buckling/crushing) and, my most particular bitch about it - located RIGHT AT THE EXTREME FRONT OF THE CAR, applying a load up through the radiator support panel, etc, with almost the entire mass of the car cantilevered between there and the rear wheels? Nope. Not doing that. Not on the regular. That structure out there in front of the front crossmember is not designed to carry load in the vertical direction. Not really designed to carry any load at all, really. The chassis rail that the tow point is connected to would be fine loaded in tension, as per towing. Not intended to carry the mass of the whole car, especially loaded all on one rail, with twisting and all sorts of shitty load distribution going on. No, I will happily drive up on some pieces of wood, thanks. That can only happen on driven wheels, and they are at the other end of the car, and this problem does not exist at that end of the car. And even then, I have been known to drive up on at least 1x piece of 2x8 each side at the rear, simply to reduce the amount of jack pumping necessary to get the car up high enough for the jack stands. What really really shits me about Skylines is the lack of decent places for chassis stands at either end of the car. You'd think they'd be designed into the crossmembers.
