hi mates have a problem with my rb20 hilux that started this afternoon. I started it up and reversed out my driveway. car died when I put the clutch in to go from reverse to neutral (does this a lot when cold. usually restarts straight away. CAR HAS HALTECH E11v2 so prob cold start tune). today it didn't restart. cranked for ages trying to get it going but wouldn't go and battery got too flat.

I changed the spark plugs now so I know there good.

mainly what I want to know is how do I make a thing ive heard of before where you connect a spark plug lead to the coil pack then put spark plug into that like a common spark plug setup so I can look for spark to rule out spark issue. im not sure how to connect it onto the coil

thanks for now mates

I would say you have no fuel then either.

Do the usual, check fuses. Then i would pull cas out and turn by hand to see if the injectors click and I'd there is spark. Then you have to set the timing due to removing the cas.

What fuses should I look for? Since its an engine converted car the stuff is in different places and probably unmarked.

I get fuel pressure at the guage near the fuel rail so fuel pumps are going I believe. Dunno bout injectors.

Setting he timing is going to be shit I rekn. Apparently aftermarket ecus don't set the timing off the Induction loop thing? And I don't know what they have set it too. Or will it just be tdc in regards to setting cas timing?

Like you said due to conversion what fuses do you check? If you don't k ow no way will I know.

The fact the pump is priming might mean the ecu Is turning on.

Fuel pumps wired to start with ignition is bad. Very bad in a crash. Should be controlled via the ecu.

Yea probs bad. I suspect that because they just run constantly once turn the key. Doesn't turn off when priming. Hopefully my ecu isn't dead. I don't believe the e11v2 has any lights on it so can't get quick idea if its getting power

I've done some more looking and thinking.

I hooked up spark plug to coil and prob have no spark.

Then removed spark plug and no fuel on it

I connected another cas I had (unconfirmed weather good or not tho) and turned it by hand with key in the on position. Nothing happened. No spark no injector noise.

My next thinking is I want to check power getting to the ecu and then follow from there. Problem is the haltech e11v2 doesn't have any lights in it to see if its powered up. Is there a way to check power to it?

It's a patch connector thing so the standard ecu plug is still there intact. I am now thinking of obtaining a standard rb20 ecu just to see if it lights up as my test for power getting to the ecu.

Any other ideas mates? Just bought house. Ment to be selling car. dream boats f**ked :(

did some more testing. didn't need standard ecu. I checked it with multimeter. has power.

what would be the next thing after the ecu I could check to make sure power is going out of the haltech ecu?

      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.

      M35 Aftermarket Fuel Pump

      By dawhitehonky · Posted

      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.

      Rapid-fire squeaking/creaking from rear suspension

      By GTSBoy · Posted

      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.

      Jacks that fit under GTR lips that can reach the subframe?

      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.
