Haltech / fuel pump problem

[GSR-94T]

Hey guys have just finished doing my cc gsr ready to start her up and i have no fuel pump car now has haltech e11 v2 in it i have back probed the wireing and have discovered that when i probe the red and white wire from the fuel pump relay the pump will prime however it is a lazy prime ( mabe because i was using a test light to prime it unsure ) however that is the only wire that has power at the relay we have put the computer in another car just to make sure everything was turned on and that car has a fuel pump and starts and runs has anyone come accross this problem before and would have a solution ?

That's really hard to read without full stops and commas.

So the fuel pump relay has power to the solonoid and the main breaker if the key is on...
Then the ecu will ground the other side of the relay solenoid, and power will flow through the main breaker and to the pump.
I hope that makes sense
In my profile I think the wiring diagram for the fuel pump is there.

I am not a grammar nazi...but it is hard to read.

Thanks Brian.
2wires to do with fuel pump should have power at the relay, a fat one and a thinner one.
Sounds like the thinner one has no power.

Hey guys sorry about the grammer. The little red and white wire has power however the black and yellow, (thick one ) that should have constant power has now power.

I think the fat one is fed from the fuel pump fuse under the bonnet.
I on stupid phone so is hard to get the info

Yeah ive worked that part out, i however do not have any power coming out of the main relay or going into it. Any ideas or areas to check as to why that could be ?

ok, im not sure on your colours but...
pin1- black/blue stripe. power from fuel relay to the fuel pump.
pin2- black/red stripe. power from efi relay to other stuff.
pin3- red. connected inside relay box to pin2 and feeds pin12 and 25 of ecu (ecu power supply)
pin4- black/yellow stripe. power supply from (efi?) fusible link in engine bay
pin5- white/red stripe. the ecu earths this wire to trigger relay and turn pump on
pin6- black. this wire is connected to earth (i think?) and is the trigger earth for the efi relay
pin7- power supplied to the trigger for the fuel relay, also for the pump, also connected to pin8
pin8- power supply to the trigger of the efi relay

basically there is 2 relays inside that box (proton actually have 2 seperate relays here instead of the 1 gold box). 1 relay is for the efi running and the other is for the fuelpump.
lets concentrate on the fuel pump side, pins 1,7, 5

at key on, backprobe connecter, do you have power at pin7, or pin8?
if no, you need to check connections at fuel pump fuse in engine bay
if yes, connect pin5 to earth, does this make pump work?

if yes, you have wiring issues or ecu issues between pin5 and (pin8 of b25 on the ecu)
if no, then connect wire between pin7 and pin1. does this fire the pump?

if yes, you have to replace gold box as you have issues there
if no, you have issues with the pump or the wiring to it...

hope this helps.

are you tring to wire the fuel pump thur the STD MPI?
you have a haltech dude take the output from the ECU (E11) and wire to a standard 30 amp relay then to the fuel pump (you should know how to wire a relay)
you can patch into the small conector block in front of the back seat floor left side.
I think it is the green wire. just disconnect it from the existing car harnes.

you also have pump prime time in the software. Haltechs negative switch. so you will need to get some B+ down the back under the seat. Then it is all hidden.
