Pump problem

[sebdut]

I have a problem with the pump she won't start when I put the jump on sys the twoo Led became yellow and the pump don't want to start

[Richard L]

Where did you install the pump?

[sebdut]

In the engine compartment the pump start when I put a wire between the twoo big red wires on the relay but when I want to start with the sys jump she wouldn't start

[Richard L]

There is a possiblity the bearing of the pump bearing may have seized due to corrosion from water ingression.

Please take the pump head apart (four long bolts) and examine the internals.

The system is designed for trunk mounted as the water pump is not water proof.

[sebdut]

For me it's an electrical problem be aise the pump start when I put 12v direct on the pump or a relay problem???

[Richard L]

I hoep it is a electrical or relay problem rather than the pump.

Link the "SYS" to energise the relay, at th esaker time, pull out the "FAV" link to stop it from overheating. Get to the bottom of the relay and bridge the two thick red wires. If the pump comes on, it will be a relay problem. Also check for rely clicking by pulling and re-inserting the relay from the socket.

It is also possible the small wires or connector are corroded, check them. They are not water proof.

If it is a relay problem, we need to find out why it failed, corroded bearing puts undue load on the relay contacts.

[sebdut]

It is not a pump problem because when I bridge the red wires the pump start it is maby a problem with the twoo lotte wire the blue and the red or the relay

[Richard L]

I think the thin red and blue wire should be on the next checking list.

[sebdut]

The pump start when I bridge but the relay don't click when I link the SYS

[sebdut]

The relay is good I have test it. The problem is that in the pr? cranck position I have always 12V on the little red wire ( even if the sys is not jump) and 8.8v on the little blue wire.......

[Richard L]

in this case, it has to be the controller.

Can youn check the soldering is good on the RJ11 socket.

[sebdut]

Yes all seems to be good

[sebdut]

Is it normally that I have 12v on the green wire when I am on pr? cranck position??? The green wire is not for the inj-? I have a french RS4

[Richard L]

The green wire is on the other side of the fuel injector coil. At pre-crank position, you should see a full 12V when the fuel injectors is not being pulsed.

Some vehicles switch off the +12v supply to the fuel injected if you don't crank the enigne for a preset period. This is for safety reasons.

It appears this is a problem on ther relay driver. Please return the circut board back to me for checking.

[sebdut]

Ok let me know your adress and I send you that tomorrow

The controller is send :-)

[Richard L]

Great, I will be looking out for it.

I have received the unit on Thursday.

I just did some simple tests and cannot replicate the problem of the relay, the system switches on the relay positively without any problem.

Since I have the unti back, I can flash in a more suitable flow table to suit your applciation. Can you tell me how many and what jet size you are using. I will send you a new relay just in case.

Richard

[Richard L]

Can you make a visual check for me on the blue harness. The order of colour in the RJ11 connector should be Red, yellow, blue, black. Counting from the gauge side.

I think this can be the problem.

Richard

[sebdut]

I have 2 0,3 nozzles pre turbo and 2 0,7 nozzles post fmic

[Richard L]

Can you please check the blue cable for me.

[sebdut]

Yes I will check it tommorrow morning

[sebdut]

Ok the blue harness is bad red, blue, yellow and black

[Richard L]

Great, I will send you a new blue harness. It is bank holiday on Monday, I will send the parts out on Tuesday.

[sebdut]

Ok thanks for your reactivity

[Richard L]

Blue harness repairing kit on the way to you.

[sebdut]

Great thanks richard have you got a track number?

[Richard L]

it was sent via airmail postn not trackable - it only takes a few day bewteen France and England.

[sebdut]

Hi richard I didn't receive the parcel yet you think that's normal?

[Richard L]

Please allow a day or two more. I have sent them last week.

[sebdut]

Great I have receive the parts today. Thanks for all very good job and very professional

[Richard L]

You have a choice of a few options. Let me know how you get on.

[sebdut]

I just remade the connector with the grip
