Hi all need a bit of info ive just put 044 fuel pump on my cos and wiring dose'nt plug on same what dose every body do cut ends off and crimp a couple of loops on or is there a better way ?

 

i had to cut and recrimp my wires when i fitted a new pump,i dont think there's any big deal in doing so providing it's done properly.i put a blob of solder on the wire before crimping though to stop oxidisation and prevent future troubles.i also had some water proof connector covers which i fitted.

 

yeh nice 1 was going to do that just thought id check if there was a proper fitting or owt id wondered about them little plug's off coils that push on if you no what i mean

 

off topiclooks a very nice 3 door in your avatari am guessing its yours

 

Don't solder the connector, there is vibration here so a soldered connector is more likely to break, a proper crimp is fine, rewire(pump circuit) if not already as well ?

yeh thats mine in pic cheers m8

 

hi i haven't rewired pump circuit av got more info ? if i trace it back in to the loom dose it unplug ect what wire where from ect

 

Do a search on here, but roughly you use the original pump feed(live) to trigger a relay to supply the pump.
You will need to run a new live supply wire from battery(through fuse at battery) to the rear of the car, I mount mine just abovethe rear n/s suspension turret, there is a hole in the metal work there which is 8mm so is ideal to mount a relay holder.
I also run a new earth to the pump/relay.
As wiring looms age they build up resistance, so even measuring 12v at the pump can drop considerably under load, as the digimetre does not take any amoun of current, where as a pump does, 18 amps at lockout on a 044.
If you haven't done the pump rewire, I suggest you also look at fan rewire.

did that search spot on that m8 cheers. by the way is this tabz who sold me this car

 

Not me sorry, someone else.

tabz is a trader on here and tabetha is a cosworth guru top guy for helping always helps me when i have a problem with my 3 door

 

Hi phil

 

here's the diagram - this is a must for every cossie
I cant remember what size cable i used but i'm sure someone will comment
a spst relay will surfice

 

hi off topic but can this method be used for an rs turbo? better to be safe than sorry..

 

Yes it is a basic switching circuit can be used on RST no problem, despite what the drawing says SPST relay will suffice, this just means single pole ie just controls the live(or earth if you want, but only one) single throw ie goes on or off nothing else.
The drawing points to a SPDT relay which it isn't!!, it is infact changeover relay.
Just forget the "87a" and get a relay with the other numbers, although the changeover relay will work perfectly with 87a, just trying to clear a little confusion.
The 87a is there as it changes over from outputting from 87 to 87a or vice versa hence it's name.

bit confused with the original red/black used as the feed is this - or + originally?so do you join then a use as one?

 

Heres a diagram I Done a while ago when I rewired mine



Maybe someone can let you know which wires goes to which terminals on the relay A,= 87 which is the 12volt out to the pump but I have forgotten the rest, I couldn't even find my old thread which had it all on.

 

that helped actually!cheers
