Re: Pump problem
Where did you install the pump?
|
Re: Pump problem
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
|
Re: Pump problem
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. |
Re: Pump problem
For me it's an electrical problem be aise the pump start when I put 12v direct on the pump or a relay problem???
|
Re: Pump problem
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. |
Re: Pump problem
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
|
Re: Pump problem
I think the thin red and blue wire should be on the next checking list.
|
Re: Pump problem
The pump start when I bridge but the relay don't click when I link the SYS
|
Re: Pump problem
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.......

Re: Pump problem
in this case, it has to be the controller.
Can youn check the soldering is good on the RJ11 socket. |
Re: Pump problem
Yes all seems to be good
|
Re: Pump problem
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
|
Re: Pump problem
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. |

Re: Pump problem
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.

Re: Pump problem
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 |
