my old mfi xr3i wouldnt start from cold aswell lol it bumped straight away and my brothers escort started to do the same he changed the starter motor and is all good now so if you have done that then im out of ideas mate

M16NTE

it could be the starter, it is a bit lazy... ill try it..

i have the same problem on my van, aint the starter though as i have a zetec one on it and turns over fine. always starts with a missfire too

stevo123

Warm up regulator not working properly would cause this issue on a 3i, pretty sure the RS uses a similar set up so this may point you in the right direction. The cold start valve, i believe, sprays more fuel when cranking in low temps.

cheers stevo... ive unplugged the cold start as it just floods the engine.. ill look into the warm up regulator..

cheers gary

i have the same problem mate on my s2 it does my head in every day but i am the same as you mate dont have a clue why its doing it the lads on bbs have been very helpful but i have not sorted it yet they did say to take it to get it set up properly so i will be doing that towards the end of the month but if it sorts it out will let you know

when i spoke to power engineering last week they told me that the brown thermotime sensor at the back of the inlet manifold controls fuelling to the cold start valve,and that it gives it about 3 seconds of fuel.
maybe worth a try replacing brown thermotime sensor.
its the one next to yellow sensor at back of inlet

kermitt

Thats what I did. I got the part number and bought one that was similar off ebay and fixed my starting probs.

kermitt

I think the warm up regulator is the same thing as the thermo time switch (check Motorsports Developments guides). This controls the cold start valve and tells it to inject more fuel if required whn cold.

Mine works backwards to that lol.

First turn when cold (with foot on accelerator) but when warm whatever it try it takes 5 -10 seconds of cranking. still starts though, everytime. and it has a very expensive head on it so i'm hoping the fucker isn't warped before anyone mentions that

kermitt

Mine was similar until I changed plugs to cosworth PP8. Starts first turn of the key with out touching the accelerator.

was that to me?

i still run NGK BR8ES. But i need to upgrade soon anyway when the boost goes up.

M16NTE

I'll jump on the owners club then copey.. It won't even start now, I've changed the dizzy cover and rotor aswel as plugs.. It's really getting on my nerves now..

M16NTE

I've changed the thermo time switch and still no luck.. Next on my list is coil and leads, if that don't work then it's sell it or convert to efi and gotec stand alone management..

kermitt

That seems like an expensive way of just getting it to start.

Why dont you take take it to somone that knows what they are doing first to determine the problem cos if it aint starting now it still may not start after going efi.

M16NTE

true kermitt, but i just want the thing to work now...
im going to have another look at the weekend if, i still
cant start it then ill get it taken to jano, at oddkidd..

copey_rs

You had anylook on this yet fella or you still got the prop as mine is still the same lol

M16NTE

hey mate, yeah all sorted now... i ended up taking it to jano at oddkiddcreations, he put a new metering unit on it for me a played with some other bits and its proper sweet now... just goes to show how much trouble a metering unit can cause..

copey_rs

So does it start first time now no messing around cutting out and that
