there's no ignition wiring connected to the afm but it is in the loom so it would be an idea to pull the loom out and check its condition.

have you ruled out/proved the TPS?

Ditto , seems like you have something wrong in the wiring/loom ..

Is the AFM properly set/calibrated ? If you wish , try to experimente a little with the AFM spring tension - mark current position , then try and re-adjust the cog wheel 4 to max. 7 tooths on the either side and see what happens .

It will start with the AFM unplugged or unpluged and removed completely , but will run rich and will smoke a lot ..

no need to touch the afm, its a remanufactured unit.

I think it is possible to get the gearbox reverse switch connector and the water temp mixed up although the WT plug should be blue iirc - does your reverse light come on correctly .
Definitely sounds like a fuelling issue with the easistart keeping it running .

Yeah, after spending £250 on the AFM I'm not going to mess with it.

The loom should be good as I sent it to Miles and paid to have it looked at.

I've managed to get hold of someone who knows their way around 205s who has kindly offered to come take a look.

So it looks like it's the fuel pump. It's making nowhere near the required pressure.

Time for a search on recommended replacements that aren't too hideously expensive like the Bosch one from mister auto.

how much are they? I wouldn't want to use anything else tbh, they last long enough too.

I assume you checked the fuel pressure regulator is good?

Also, worth pulling the pump out and checking the short length of fuel hose inside hasn't split - it's not unheard of.

There are 2 versions £200 - £300.

Ive not checked the pressure regulator but pressure was under 1bar on the fuel feed. It was Rab Elliott from pscuk that came round so a reliable gauge was used. He checked the wiring and ran a live feed direct to the pump and said you can even hear it's not right.

I think I might have a pump for a 1.6 you can have if you don't mind collecting it.

Pretty sure I could manage that if you're somewhere around the Glasgow area.

Not sure how many pump types there are. My car is an H reg 1.6

Two GTI type pumps - early models have a black housing, later models a white housing. 1.6 and 1.9 makes no odds.

Yours should be the later type if it's a Phase 2, but H reg is when they changed over.

does the colour determine its flow rate?

I just remembered that I'd previously dug it out for someone and iirc it's black. It's there anyway if needed.

Small world as I was talking to Rab a couple of weeks ago.

Do this first off. Then try clamping the return hose with the pump running to see what pressure you get, to prove the pressure reg.

I'll pull the pump out, see what version I have and will check the hose inside. I may be in touch dobboy.

I'll probably just replace the pressure regulator anyway. It's about the only part left in there that I've not replaced now.

Thanks all for your help.

I wouldn't personally just change it for the sake of it. With the pressure gauge on and pump running then restrict the return hose from the regulator to the tank. If the pressure increases your fuel pump is up to the job but the regulator is not. If the pressure does not increase then the pump cannot deliver the pressure regardless. But also have the pump out and check the rubber connection inside from pump to housing!

I've already tried that. Clamped the return hose after the regulator and it had no effect.

Change pump and re test pressure fingers crossed should sort it. I'd check the rubber pipe in the pump housing before ordering a new pump though.

Pump is out. Black housing so earlier type. Does this look the same as the spare you have dobboy?

Rubber hose doesn't appear split.
