Hi all, Some of you may have been following my project thread, when I converted an
AGG auto into a ABF manual, I had it on the road last year for 3-4mths before I burnt the main loom out, so I bought a new loom, and started this week to replace it, So, all was going well, until today I went to start it.... It didn't!

It tries too, and will start with some persuasion with a little throttle, but is rough as!! And running Very rich, as soon as i let go of the throttle it cuts out immediately.. I'm going to try changing the leads and plugs tomorrow, see if that helps

The ISV is buzzing when the ignition is on, never heard this before, or never noticed it before, should it do this?

While the engine was out, I did remove the inlet manifold to clean up underneath...I put it all back together as previous, I replaced the gasket too, I probably shouldn't of touched it in hindsight lol

Any ideas?

Overfuelling wise.
Temp sender, maf or lambda id have said. Did you hear enhine running before you removed it?
Also if you scan it any codes

Yep, I ran it last year before the loom melted. And I used the donor car for a while before I stripped it for the engine and box.

It came up with a few codes, I didn't write them down like a fool, one of the was engine speed sensor, will check the inlet tomorrow. I replaced the gasket with new..admittedly aftermarket, tried VW but it's been discontinued.

you may have damaged the engine speed sensor / crank sensor cable whilst doing the transplant. They go very brittle over the years.

I replaced mine a few weeks back, after similar starting and running issues like you've described.

I was going to say that crank sensor wiring or sensor seems like the issue

Just done a scan,

It's come up with

00513 - Engine Speed Sensor (G28): Implausible Signal

And

00740 - Cylinder 1 recognition sensor. (G145) No signal

Figured this is the Engine Speed Sensor





New sensor then.

ISV buzzing is a good thing.
as long as your engine idles when warm you dont need to worry about it

It's not starting mate, only with some throttle, When I hold the throttle down it keeps running but very rough, if I let go it cuts out. The wires to the crank position sensor are frayed, so I have a new sensor to fit tomorrow.

Yes - Crank sensor will stop it starting.
You were asking about the ISV in your first post.
If you can't feel it vibrate with ignition on you have a problem -as yours is buzzing like a jack rabbit you should be ok here
