Stagea S1 Not Starting

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.

      Yep, that was one of the things we learned fast in the past with our MX5. When you drive with the top down, you are effectively standing out in the sun, 100% of the time, and not getting in any shade (because roads aren't shaded generally!). Just like standing out in the middle of a field on a sunny 27C day is a bit of a bad plan, so is sitting in a MX5 without sun protection.

      I also just ordered some Frankenstein bolts and side mounts to fit a hard top Just in case I do find one, basically so it doesn't need to be fixed to the car with only the front latch.......and then gaffa tape to keep it in place for the RTN journey from wherever I get it

      If your temps are fine now, you probably won't have any issues with where your vents are as they don't look right up at the windscreens high pressure area, so any differences when giving it the beans for extended happy laps would be minimal, but, they should vent heaps when stuck in traffic  Much like how that reverse cowl on my SS let "visible" heat out when stationary, but, because it was basically at the windscreen my coolant temps on the Hwy actually raised because air was being fed into it at speed (110kph), to only come back down to around 90° when I got off the Hwy And your 100% correct about the NC currently not needing vents, but, if I was to add a turbo, and a oil cooler and intercooler in front of the condenserand radiator, and then take it to the track???? It is apparently a recommend requirement if I don't want to worry about coolant or oil temp issues, but, any of the above are possible scenarios, over time As it sits now, with the triple pass radiator and stock air conditioning system, I have absolutely no issues with either temps or air conditioning efficiency, I've been basically daily driving thie car for the last month, both on the Hwy, and peak hour, bumper to bumper traffic, but, that's pretty much expected from basically a standard engine  Talking about no issues daily driving, it was 39° the other day and I was sitting in bumper to bumper traffic on the M5 and then M7, with the top down, and with the air conditioning blowing nice cold air on my feet, balls, and face, well, there was one issue, my head and arms got pretty sun burnt Note to self: leave a hat and sunscreen in the car for such days 🤣

      I would agree, unless you need something specific to the HV motor/battery side repaired or investigated, any mechanic will be able to perform normal services, but if you prefer, maybe look for a mechanic who regularly services/repairs Nissans, the VQ engines are pretty common in the Nissan lineup.  Sorry, I can't make any suggestions, I don't live in Vic.

      Some of them keep working fine. 9 out of 10 of them end up causing an absolute misery bleeding the system and get thrown on the workshop floor in a tantrum and never thought about again because they were never really needed and just added crap to the car that we could have done without. Same-same with HICAS, A-LSD, and various other stupidities that over eager 10x engineers thought we had to have.
