']i have a DR30.

yeh the diagrams on FJ20.com are the 2 that are no good. its a 2 page diagram of the ECU wiring. i need the full wiring diagram with fuel pump etc on it.

OK,first thing you must have is a test light.If you had a burning smell first check all your fusible links(on mine there is 3 at the battery and 4 at the fuse box)

The fuse box (drivers side firewall) contains all your fuses and relays including your fuel pump relay.If all your fuses/fusible links are ok you should have power to all the relays and the fuel pump relay should click off after a few seconds with ignition on.If all is ok connect your test light to the fuel pump and with ignition on or engine cranking you should have power to the pump.

Try that and see where you end up.

Yeah I was thinking today that I want to be able to see the screen easily as I'll use the speedo function (will calibrate with a GPS) so I might put it on top of the steering column inside a tek box so it looks like a Jaycar digital speedo.

Does anyone know how that annoying 114kmh beeper works? Does it just get a signal from the ecu when the car exceeds 114, or does it recieve the speed signal?

whats the device that makes the beeping noise?? is it standard or after market?

ADAM,I'm not sure if it runs off actual speed,or just an ecu output,as you say.At a guess,I'd say it runs off the speed sensor wire,the units in HR31's do....

What I am sure of,is if you want to compleatly remove the whole 'ding' module,and stick it in a postpack I'd be more than happy to shout you a couple of beers :rant: or send it $10 COD.... I WANT ONE!!!!!!

My mate has an S13 180SX and he can't change the sensor, but the beeper itself simply attaches to the back of the speedo by 2 screws.

He removed the beeper/speaker and NO MORE NOISE, but you have to put the screws back, something to do with open circuits, as others have removed the beeper, left the screws out and had problems with the speedo fluctuating.

well i went outside today to my car to pull the dash apart and look for any burnt wires but decided before doing that id open the fuse box and turn ignition and listen for any of the relays ticking over to try and find fuel pump relay.

anyway, turned the key and *bzzzt* pump was back to life. power was back to it again. i then turned it on and it was super lumpy and rough. checked the pressure guage and it was reading 41psi idle pressure rather than the 34psi i set it to the day before before it died. then found out that the guage, rather than sitting on zero, was actually sitting another 1/4 of the guage face further down, below the vacuum area (guage had vacuum bit on the bottom 1/4 of it). so it was probably about 15psi out or so :P so wen i connected it initially and thought it was at 19psi, it was probably at 34psi like i wanted. and then wen i turned it up to 34psi, it was more like 50psi idle pressure. so wen i took it for the 2 spins round the block, it must have just overloaded the system and thats y the wires were burning. ECU must have noticed and cut the power to the pump at this point i guess.

so i connected another guage, disconnected the 2nd air valve thing that i had hooked up yesterday when it was at the wrong higher pressure, and got some new plugs since the old ones were all fouled up, and it sat and idled perfectly at 34psi idle pressure.

so just gota take it for a drive tomorow and see how it goes, see if it still has the huge misfire that it had and if it starts to get too hot and short the wires again. hopefully no permanent damage was done but we'll see tomorow i guess!

Its located underneath where the head unit goes in the '30s I think.  If it gets a feed from the speed sensor wire then that would be quite useful

Its to the right of the cig lighter, those three lines/slots in the plastic allow the noise to come through, is a little metal box behind the slots.
