Hi,

Ive just fitted my new engine and fuel pump looms,

Now the problem im having is injector 2 is pulsing constantly with the ecu pluged in, and the fuel pump is intermittently pulsing.

Cylinder 2 is now full of fuel,

if i try injector 2 lead on the other injectors it has the same effect

Ive also tried ISCV lead and they dont appear to be crossed over?

Also the secs monitor isnt switching on although it is wired correctly and there is power to the ecu?



any ideas would be appreciated


BTW spec is ;msd coilpacks (with wrc cam trigger) grey injectors braided engine and fuel pump looms,044 pump etc

CPS and Knock sensor plugs are most likely crossed if you have just fitted it Ben.

cheers il go try now, but they are on as labbled

ive tried swapping them, disconnecting them and they dont seem to affect it at all

iirc, my chip was in the wrong way when mine had symptoms like this.

can you remember this Rob.

The DIVA

iTrader: (3)

Yeah remember that mate, Ben check the chip is in correctly(Notch facing to the left with the ecu connector facing you) also check the baby board is plugged in correctly(The spare holes in the socket should be visible to the left of the board plug)

faulty earth?

Ben, i`ll ring you in a bit mate, just gotta go sort something....

benporter

Board and chip were fitted by msd , but Ive checked anyway and its right from what you've said.

I was thinking earths but wouldn't know were to start tbh

benporter

iTrader: (1)

Ok cheers

the injector earth mate

see if there is power to it using a test light so at least you can eliminate it from your problems

i toasted my 3 door when one of the injectors earthed out and i had neat petrol pissing out of the turbo housing when i opened the bonet, and the next thing, it went "poof!" and up in a cloud of smoke

rscos2004

I had a similar problem with mine and its so easy to put the wires on wrong also check temp cooleant sensor is plugged in.

As "dojj" said : injector earth.

Check if connector nbr 32 is on earth.
(number is the same for all ECU)
If yes, your problem is here.
It was a very old campaign on RS, engine wiring was in contact with injector fuel ramp.

Regards.

Did you sort this Ben - I have the same problem now.

ive had this it was a fu*ked ecu, loads of companys test and can repair l8s for around £120

i had this i had my injector plug on the wrong sensor cant remember. just make sure all the wires are the same colour on the injectors.

When I had this fault there wAs broken wire in loom which kept the injector on an open circuit. Ran new wire in direct to ecu and fixed

kjc300

I'm *fairly* certain there's nothing wrong with the actual wiring itself - it's a Ryan loom (not that old).

Checked all the routes to earth on all hairbrush pins (from pins 1 /19)

All engine plugs fitted - ecu removed.

Not found anything massively wrong I don't think - couple of things I'm not entirely sure about though:-

ISCV pin 34 - multimeter beeps with 007 on reading

Fuel pump relay - pin 28 resistance reading 087 ish

Ecu relay - pin 10 resistance reading 087 ish

Ign amp - pin 24 resistance reading too can't remember what though.

No perm earths on inj 2

inj 2 not stuck open (tested with rail out, no injectors plugged in)



ECU does not run Matt baxters car either - which is similar setup - his no 2 injector does the same with my ecu.

No i haven't fixed mine yet, the ecu was tested at msd so its not that

-beefy-

iTrader: (6)

personally i wouldnt rule out the loom ,

granted its a new loom , but probs can always arise ,

think folk automatically assume at its a new part ( in genral ) that it should be in working order ,

over the years weve trace plenty of faults to a new part fitted ,


just my input


hope you sort it fella


beef

before you go mad changing bits, feel free to fire the ecu back so i can double check it ben

benporter

iTrader: (1)

Cheers

il have a mess about with it this week if i have no luck il be in touch

benporter

iTrader: (1)

Slight update on this,

Ive removed the secs monitor with no change

ive removed the earth from the inlet with no change

ive disconnected every sensor and it still dose it


Ive also now found that a couple of the plugs are firing randomly as well

Sent my chip back to be checked out Ben, hopefully find out tomorrow.

MSD chip? my cars at msd now all fixed, was a problem with the encryption and baby board

COLEYST200

iTrader: (3)

So let me get this right you sent the ECU to MSD and they told you it was OK . So to get it sorted you had to get the car to MSD and it turned out to be a problem with the ECU

I would wont to no why they did not find it when you sent the ECU to them to be tested

benporter

iTrader: (1)

That was just for the injector staying on

the car had other problems to be sorted out that's why its there

kjc300

iTrader: (1)

Yeah MSD chip - I'm hoping mine is encryption board - need the car for the weekend!!

James @ M Developments.

iTrader: (2)

because its a dodgy ribbon cable conection, wiggle it and its fine just like it is now. hardly an ecu fault....

also the car wouldnt start due to the wrc cam trigger sensor gap, which did not function when i ran a scope on it.

runs just fine now.

thanks for the concern though

James @ M Developments.

we are on the case mate,
