Why exactly OEM gauge, you could easily improvise with another pressure gauge reading max at least 5 Bar.

Exactly what I did in the end.

Pump voltage also, the el.socket is not super tight, so two thin wires could be put in the female orifices before plugging the socket, then use these two for your volt meter.

Have to check was there an easy way to clear long term trims.

So the pressure seems good, basically at 3 bar(g) consistently, even when it runs up the revs or stalls.

I have managed to find the number which changes LTFT to 3.0 (slider error still unresolved), much closer to 0 than -60.

So what I am seeing now.
At LTFT around 0 it fails turns over but doesn't rev to idle.
At LTFT around -10 it will remain stable but burning rich and smelly throttle response is slow to opening or closing.
At LTFT around -30 the application of the throttle will cause it to run up through the revs, even when throttle released.

So either burning rich or not at all. The opposite problem of previous lean burning.

I'm starting to think major vacuum leak from somewhere. Partly because if I manually cover the IACV to restrict air flow at idle it's still pulling air in from somewhere... Also looking at the throttle body vacuum it's far lower than it was when I last tried balancing it.

Potentially it's a throttle body gasket? Or maybe something else...

Still to replace injector seals, they arrived today.

Will it run with the choke out?

Nothing works, booked a mechanic for friday, hope he can figure something out, she runs on starting fluid though but if you try to accelerate something bangs inside.

A bit of a stab in the dark, but could it be a bad earth somewhere?

I say this as my current project, a Daytona T595 has a very intermittent start circuit, sometimes press the starter& it'll turn the engine over, sometimes it doesn't. My issues aren't identical, I have a lot more electrical gremlins that just the one, but they seem to be earth related.

It may also be relay related. At one point the only thing that worked when I turned the ignition was the fuel pump and a click from the ECU, everything else was dead. I replaced all the relays & while it didn't cure everything, I did manage to get the engine to turn over & most of the light to do what they're meant to.

Well, that would be something, they are tip 152, one of them had leaked (coil 1 driver) but my electronist said its no problem. Ok will change all 3 tomorrow and see what happens.

If you dont let the engine start (wot) you get constant spark, soon as she fires and sparks have to be faster they (sparks) just fade away.

Of course it's a power delivery issue from the ecu, has to be.

Looking back over the forum, there is some evidence that the ecu transistors can fail on the T400, so hopefully the repair will work. Luckily they are not totally SMD boards. I did have one in bits years ago, but unlikely to have the photos anymore..

Just hope it's not broken

The cdi I bought was 48 gbp 
So yeah, we'll see, I'll check all of the fuses just in case, reconect the battery just in case and take apart the start stop, maybe a hot wire loses conection, maybe...

Good price...

And regarding the fuses, the connectors can become bad, both the main connector for loom to fuse box, and under the fuses themselves.
It's been a few years since I had my Steamer, so I'm struggling to remember, but I don't think there are any other fuses.
