Hello!

I've had my Stagea now for 2 weeks and the other day it just wouldn't start. Everything seems fine exept I have no fuelpressure. It seems there's no power reaching the pump.

Does anyone know where the fuse is? Also is there a relay? Or even better, a wiring diagram?

It's -4 fahrenheit outside so Im not really keen on pulling every fuse and checking. :)

Cheers

-4 F sounds cold.

There is a fuse, it is under a cover on the driver's side lower dash. This is the layout:

So check the 3rd fuse and make sure it has not blown. A bit of a long shot but at least it is easy to check.

Do you have a multimeter? If so, use that the check the fuse, and if not....take another car to the shop and buy one :)

If the fuse is OK the best thing is to get straight into the fuel pump wiring. Open the boot remove the boot floor (a couple of 10mm nuts from memory) and you will see the fuel tank cover. Remove that too, and unplug the plug with 2 wires (fuel pump wiring, the other plug is the fuel level sender and warning light). Turn the ignition on and immediately (ie within 2-4seconds) check for 12v between the 2 terminals of the plug. If there is power there the fuel pump is not working (no fuel? pump dead? fuel line froze, I think the last one is a joke?). If there is no power there you have an issue in the ECU, relay, wiring or power supply.

But before all that, do you have an immobiliser that may have failed? or is it out of fuel? why do you think there is no fuel pressure, do you have a gauge?

Thank you for your reply Duncan.

I measured the current yesterday and there's 0v going to the pump. So probably, like you said, ECU, relay or wiring. Do you have any clue which one of the relays belong to the pump? Is it common for the ECU to fail?

I really dislike these kind of problems.. Especially since I have no way of getting the car to my garage.

I don't think there's a immobilizer.

I have a pressure gauge in the enginebay.

I start every sentence with "I" :-)

Cheers

Hey Miltuun, -4 deg fahrenheit is like 36 degrees of frost in the "old money". You gotta get outta there man. :yes:

Did you check/replace fuse like Duncan suggested?

Did you check voltage at disconnected fuel pump connector in boot within 2 seconds? Need very long test leads (& no sparks) or two pairs of eyes for this, especially if you are on ice. :wacko:

Best of luck with the fix, let the forum know how it turned out.

Cheers GW

Woop woop, problem solved. A shady turbo timer installation was the problem.

It now runs smooths as ..something. I will solder it together in the morning. You guys are missing out, these cars are great on snow/ice :yes:

Thanks for the replies.

Good find! Personally I think turbo timers are the devil as they give car thieves an easy starting place to rip off your car. Got any pics of your Stagea in the snow???

Haven't really thought about it but you're right. Maybe I should remove it since I don't even use it..

I'll get some pics! I only have crappy iphone ones right now.

      Uncle Duncan Yeap, FI Interchiller  Works well, normal IAT's cruising with the WTA only went from 50°c+ to 25-30°c with the interchiller  Before, when on it hard, the IAT would see 80-90°c, now, the highest has been was around 38°c IIRC IAT is measured under the blower hat I recommend it for the street or strip where your only on it hard for 10 or so seconds, but it wouldn't be efficient for sustained track use as it would heat soak from the AC turning off or whatever it does during WOT to protect the compressor It really needs the AC running for it to not heat soak and keep the WTA coolant chilled My WTA coolant temps when just cruising is around 2°c

      Hey Mark...sorry to interrupt your career change to hair dressing... but...did you ever fit the interchiller to the commodore, and if so how was it? And, who made it?

      I've been pondering this, I really enjoy the convertible thing, for me, it's like riding a motorbike, without all the issue of riding a motorbike, mainly, my old sore arthritic joints getting beaten up, and, being able to do it in shorts and a T-shirt and not needing a helmet and all the other gear required, especially like wearing jackets and pants in the summer, or needing 6 layers of cloths in the winter, or not having wet weather gear handy when your 100km away from home on the bike when it decides to start raining As for the hard top and its Coupe look, whilst I do lose all that open top feeling that I really enjoy, from my experience with the NB with a detachable hard top, the cabin is a much nicer place to be, the difference in noise for one, a hard top quietens down the interior, alot, with the soft top up or down it's pretty noisy, which, after 5 or so hours, can get tiring But, as you stated, the detachable hard top totally changes the look of the car, in a really good way, and for me, the look of a detachable hard top is so much better than the PRHT which looks more like a after thought with its weird bulbous rear roof line For me, the minimal effort of putting in on, or storing it after removing it, is well worth the time and effort for the look alone And yes, I'm sure the next owner will be grateful for it as well.......
