I've briefly mentioned this in some other threads on here but as it made its show debut at JAE this weekend I thought I'd put up some photos!

I bought this 3 months ago as spares or repairs with a view to making some money on a 1G-GTE engine.

It is the widebody variant, in Black Ruby Pearl (206) with the 4 speed auto. Oh yeah, it's only done 46,000 miles!

However when it turned up I decided it was too good to break so started troubleshooting. Everything on it works bar the electric aerial (even the air con is cold). It had a few mods which I removed, and had obviously had loads of troubleshooting done on it already, but the kind of "throw new parts at it" sort of fault finding. So, it was freshly serviced with new ignition components (including HT leads).

The fault description I got when I bought it was that it would start and then die. Sometimes it would start and run for 20 minutes, sometimes it would be 5 seconds. It would always start, but not run for long. When I got my hands on it and started mucking around I could only ever make it run for 10 - 15 seconds at a time - it ran much better if you started it with your foot to the floor but it would always eventually die.

I sold the Nissan Sunny, went to Le Mans, then had my birthday, went to Goodwood and the Red Bull F1 factory... then once I'd got some free time I started working on it. I'd got some distributor fault codes, so started there.

Nothing dodgy going on there. Checked out the coil...

... brand new. Not that then! Buzzed out the wiring from the ECU...

Not that either! Following a few backward and forward exchanges with some guys who do this for a living and having spent days ensuring there were no air leaks anywhere we decided to open up the AFM. Now normally this is something you'd never do under any circumstances, but this one had clearly been opened already!! So I got a scalpel out...

All good in the hood. Then when I was mucking about a bit more, I burnt my hand on the fuel pump resistor. I know they get hot, but the car had only been running for a maximum of 5 seconds with this fault. So, I bypassed the fuel pump resistor and it sprang into life! Put all the tools away, reconnected everything, got it off the axle stands and drove it out of the unit, all the way to the end of the farm track and back, at which point it died again while idling. I ended up running a live wire from the battery through to the fuel pump in the boot for testing, and it seemed to be working OK again for a bit but then died even with a dedicated live feed, and it was clear at this point that the fuel pump wasn't running. Unfortunately while the wiring connectors are accessible from an access panel in the boot, the pump itself isn't. You have to drop the whole (70L) tank!

Swapped in a new fuel pump and job done! Chucked it in for the MOT and it failed on a stuck rear brake caliper and wipers. Caliper came off and went to Bigg Red and came back like this:

Always very impressive, as you can see I got the carrier cleaned up and painted at the same time.

1hr later I had an MOT! I've been driving it about ever since and the only issue I've had with it was the undertray coming loose, which of course I have fixed with cable ties.

Then it was detailing time. I don't have too many photos of it but here are 3 - Dan probably has more:
