Don't where you are but I just bought a standard kit (inc lifters) from Lloyds in Wembley for £75 and they had a least 1 other in stock.
I'm a bit surprised at the above because by no stretch of the imagination
could those compression figures be described as OK.

v6matt

lol looks like theyve had my pants down then it was from leicester near where i live,all seems ok now its just the electrical problem with the cold starting ie the relay side of it need the help of safechav or someone good with electrics cheers

SafeChav

Now its mentioned those compressions are a bit low, i can't remember what had been/said and done at the time.

Was that compression test carried out cold because something tells me it was?

I'll have a look at the diagrams and try and help you out ASAP

v6matt

thanks a lot i appreciate it

forgot to add it was tested from cold , it does run sweet when its warm its just getting it started from cold im pretty sure its electrical now and it is a s1 loom with a s2 relay

thanks again

SafeChav

Compression tests should always be done from warm, but when i looked back at them they are a bit low, i honestly can't remember why at the time i said they seemed ok, should be around 10 bar at least (150psi)

So hows it going anyway?

v6matt

once its been running for a min or two its sound. its just a slut to start from cold ill get a new fuel pump relay tomorrow but its that other relay and i cant get one from nowhere

v6matt

also forgot to add ive got a s1 loom and a s2 engine with knock sensor and 90 spec chiped ecu does thie combination make a difference

v6matt

Just looked this up on Microcat for you. It lists an Ignition relay and a Fuel relay for the S1. Thing is the descriptions are not entirely reliable and I'm not sure which one you need. They have different part numbers

Ignition V85AB 14N089 AA FINIS - 1627665
Fuel V85AB 9P704 BA FINIS - 1630562

All I can suggest is that you look in the fuse box, find out which one you don't have and order that one.

v6matt

thanks mark. the connector what the relayfits into is a green colour with four wires going to it and its located next to the pink fuel pump relay under the dash near the pedals, i havent go a clue what colour the actual relay is as ive never had one since doin the conversion cheers again

SafeChav

i had a look on microcat earlier and i'm pretty sure that's not the relay

MarkN

But you should have both of the above relays on a S1. If you look at all of your car's relays and compare them to the part numbers above you should find that one is missing.

Whichever one is missing is presumably the one you need to order.

It would be much easier if an S1 owner with the correct relays would have a look at their car and read off the part number they have on the relay with a green socket...

Not much more I can suggest really

SafeChav

yea i mean the description doesnt sound right.

v6matt

sounds good, as above any s1 owners fancy doing me a big favour and put some part no,s up please

MarkN

Microcat's descriptions are always a bit hit and miss though. Having looked down the complete list of Mk3 Escort relays they seem the only two likely candidates however.

v6matt

thanks v much both ill start another thread to see iff any ones kind enough thanks again

allbluepete

sure i read somewhere that you couldnt use an s2 ecu on an s1 but was ok the other way round,you got a part number for the relay mate as i've got a s1 engine loom lying in my garage doin nowt,you say its the one with the green plug?will have a look for it later

SafeChav

Its all interchangable although to use a S1 fuel ECU on a S2 you have to do simple wiring mod.

v6matt

no matey its the other way round ive got a s1 wireing loom with the s2 hash diamonds ecu and the black ecu

forgot to ask will this cause any conflicts as the other way round requires a mod, surely this will? or dont it work that way

SafeChav

no the fuel ecu is ok, however your S2 ignition ECU won't work at its best on a S1 loom, but IT WILL not stop oit starting, it will only have issues with ignition retard when driving

v6matt

that would be great if u could and yes its the one near fuel pump relay


safechav do i need to get a s1 ignition ecu then. will it nacker owt up when drivin it with the s2 ign. ecu cheers

allbluepete

rite mate got what i think is the relay you need,the code on it is v85ab1 4n089aa and its black in colour,now you can either give this code to your fordy parts man,or pm me your address and i will send you this one foc,cos thats the kind of guy i am lol

SafeChav

thats the relay you need

v6matt

cheers both finaly seem to be getting somewhere ill send u a pm with me address, u do the same ill send u a drink, thanks again really appreciate it both ta.

ill let u know how it goes

allbluepete

do that m8,hope it works for you

allbluepete

did you get the relay mate,did it make a difference,fingers crossed eh

SafeChav

Guessing its fixed his problem now he isnt quizzing us anymore

v6matt

lol im not sure it has im gonna try starting it on me way out this morning seems to be flooding itself but noticed a multiplug the wrong way round so swaped it round to the right way

im gona try staring it now and ill let u know later thanks again

v6matt

bollocks.does it fook want to start, the new relay is cliking pump is bridged
cant think what else it could be overfueling? it will start straight the way if i heat the plugs up with blowtorch
are the ecus compatible with the loom? i cant think what else to do starts fine from warm and was running spot on yesterday anymore ideas

SafeChav

the ecu's should be fine on that loom

v6matt

at least thats one good thing.

any ideas why, once its started although a slag to get started it runs fine just gettin it goin from cold tis a strange one i admit. if i knew someone local experienced with these old fords id have them do it

whats the black n yellow wire that goes to the s1 fuel relay do as i dont have a relay its just bridged at the mo

any ideas however stupid it may seem give it a go because it is something ive overlooked

SafeChav

Black/Yellow is a cranking feed to the ignition ECU IIRC.

Have you checked the fuse inside that relay you have just acquired?

v6matt

does that wire to the ecu need to be connected to anything ?


also the fuse in the relay.i take it its something on the circuit board do i do a cont test? all i know it clicks when i turn ign. on .

SafeChav

Errrr, i'm not actually sure what the effects will be without that wire connected

The cover should be unclippable on the relay, it has a 20mm glass fuse inside, if its blown you will have cold starting problems.

v6matt

opened it up as u said about the fuse. cant see the wire as its full of white sandy shit.so im assuming its fooked ill replace it and let u know cheers matey

v6matt

nope still the same ,while cranking its trying to fire up then after 40 secs or so it will fire up could it be fuel related draining back? just dont know what it could be now soon as its running turn off flik the key with no gas and it starts in a instance just some thing stupid but what

v6matt

just been out now after work and it dooes seem to be stilholding pressure at the metering head, theres some resistance on the paddle thingy till i press it down once and its gone i assume thiss is a good thing ie. no leaky injectorrs n no nackered one way valve on the pump

any ideas does this sound right

pete havent forgot u matey

SafeChav

The pressure shouldnt go with one press, but the flap wont return instantly it should rise steadily and smoothly

Hi Allblepete, I bought my R1 five years ago and dry stored in the garage.
The RS1 has never started because of a missing injection module relay (V85 AB1 4N089AA).
Do you have any this relay (V85 AB1 4N089AA)?
Can you sell me one?
Best Regards
Tony
