car has died,

has ignition and fuel pump feed

i think its the ecu or fusebox?

who is good at electrics on these that can come over for a job

i pay well!

f*king car!

 

who good is pay well
i know the problem

 

you been trying to find the prob until 3am dave

that london is a bit far for the claw or im sure hed help

move up north you southern shandy drinking bastard

 

I had Dingy come to my house to sort the 3DR out a while ago and all is fine now

They say Money Talks Dave, get ya cash out and Tempt to Claw down to you

 

so it is true what bubba says then

 

Indeed Mathew, and he didnt even touch the sides

 

i hope you sort it dave,, its a little far for me,, unless i would come for a nosey

 

not to 3am Matt, i'd just got in with the car on the back of a low loader!

on cranking the car, there was no power to the injectors or the chg temp sensor so im guessing all sensors



secs monitor shut down as well


and i need the fuel pump wired up so it primes and then switches off on the ignition click of the barrell

its priming constantly at the mo

 

Dave, have the multiplugs for the engine loom been removed?

 

no Daz

can someone give me a guide to what pin does what on the ecu ??

 

Dave, where abouts are you in this land of ours ??

 

I think this is all correct. Had to get it from my diagrams which are not that easy to follow...

pin 1 earth
pin 19 earth
pin 2 lambda sensor
pin 20 positive power feed
pin 3 crank pos sensor
pin 21 not used
pin 4 crank position sensor
pin 22 knock sensor
pin 5 distributor connection
pin 23 distributor connection
pin 6 knock sensor with earth bonding sheild
pin 24 ignition module pin 3
pin 7 canister purge valve
pin 25 ign module pin 6
pin 8 electronic control loom
pin 26 not used
pin 9 linked to pin 30 (MAP and throttle pos)
pin 27 electronic control loom
pin 10 EFI power delay relay in fuse box
pin 28 fuel pump relay
pin 11 map sensor
pin 29 coolant temp sensor
pin 12 not used
pin 30 map sensor and throttle pos sensor
pin 13 octane adjust
pin 31 air charge temp
pin 14 octane adjust
pin 32 injector 2
pin 15 map sensor
pin 33 injector 3
pin 16 boost control valve
pin 34 idle speed control valve
pin 17 throttle pos sensor
pin 35 injector 1
pin 18 injector 4

 

Daz, appreciated mate

Si, apparently 150 miles from your mcdonalds

 

Check these pins. Power on 20 and earth to chassis on the other 2.

On the Escort it takes it's power feeds from one common soldered joint... VS-1229....but I can't locate this joint in the diagram....I am still looking...

 

Dave did you get my pm ?

 

cheers Daz

Dave, i have received a few pms, but ove been so focused on the car this weekend i havent checked them out yet, ill look now

 

just checked it

speak to cossymad abut the coilovers, he specced mine so can do the same as yours

and the ride quality on soft is no harsher than my old koni's

 

Dave,

Fuse 3 feeds the ECU, injectors and varius sensors and valves.

Relay 8 is the power relay for the management system.

Fuse 25 feeds the fuel pump and also feeds fuse 3...

If the ECU has lost its earth then the management relay won't work....

 

dave where abouts are you again?

 

Ryan is the man sorted me out with my elecy gremlins andhes doing more next week

 

Relay 9 is fuel pump...

Fuse 5 is fuel pump.

 

cheers Daz, ill check those now

Ryan, im near Dartford.. not too far from you

 

lol

let me know if you dont get it sorted.

I'm sure we can sort something out

 

right, UPDATE

pin 20 is only getting 8v!

i fed a feed direct from the battery to the pin, voltage 12.18v started the car and

she burst in to life


so that narrows it down to that cheers all

now... why is the ECU feed low on voltage?

where does it feed to?

its a blue cable with a yellow stripe

 

glad you narrowed it down mate

you got the wiring diagrams to check?

 

Dave, speak to TT or Damo and get that auto sparky number of the fella that done TT's motor.

I hear he's the dogs hanging bits.,.,

 

darren?

hes the bloke that fitted my alarm and quite possibly caused this!!

 

Erm i dunno his name mate? Could be - but i'd be surprised if it was tho?

Hope ya get it sorted...

 

possible loom issue?

dont escorts have a 2 part loom ......with a connection thats prone to causing such things?

 

yeah mate at the back of the cam cover.

 

Dave,

I hav'nt read the whole post...

BUT it is very important that you check the two multi-plugs on the main engine loom........these are situated near the righthand side inner wing near the coil.

If you take the connectors apart, you may well see corrosion/grey/green residue on some (or most) of the pins.

The remedy (temp) is to clean all of the pins......Better still for the long term, is to do as Steve C and others have done - replace the multi-plugs by direct wiring/sleeves

 

or get a new loom

 

.... on a saph.

On the inner wing by the coil on an escort

 

ahh ok

 

Doug et Ryan

The car has had the multiplugs removed and joints soldered as a means of course years ago.

Why on earth would the power feed to the ecu be reduced to 8v???

Looks like dash out to trace the wire back.

couldnt i just rewire a feed to the ecu? is it ignition based or perm?

im guessing the ecu retains memory so it will need a perm feed all the time.. but this activates the fuel pump etc...

what voltage is PIN 20 with ign off?

 

Dave, Pin 20 Is a Live feed from the Power Relay, so i pressume its triggered by the relay on (ignition on) and thus is not a direct constant 12v Feed.

I will double check though

 

ok ryan, well all i need to know is ..

which relay in the fusebox? theres loads!

anyone??

 

Not sure about an escort, but on all sierra models the 2 relays (ECU power and Fuel pump) aren't in the fuse box, they are located nearer the ecu connector.

 

let me check in a sec as i got a couple of spare fuseboxes in the garage, its not the same car granted but might narrow it down.
