NO, you don't need to ground the blue wire to activate the pump, use the "TST" jumper link. Do not run the test fom more than 10 seconds at a time or you will risk overheating the inline valve (not design to be static).

Grounding the thin blue wire at the relay end is only for diagnostic work. Grounding the thin blue wire energises the 40A relay and power-up the pump.

OK i am having a problem that the pump does not prime when i put the jumper over sys...i have checked and power is getting to the relay however no power is getting to the pump. The power wire to the relay is getting power...12v (verified by the multimeter) however the red wire that goes to the pump is not getting power...do i have a bad relay?

Can you tell me if you are using conventional or direct injection mode? What car is yours?

Can you check if the thin red wire is getting power (on the 40A relay)?

I am using it in an evo8mr jdm - so conventional mode

thin red wire from control box to relay is getting power....
the red wire from 40A relay to pump is not getting power.
thick red wire from battery to relay is getting power

It might be a silly question, did you put 15A the fuse in?

Yes i did.
Talking to Jeff @ Howerton we realized that the blue connector is wired incorrectly...it is supposed to be red yellow blue black however it is red blue yellow black.
I sent a pic to him and he most likely will forward to you.

I was wondering if both Jeff and I were talking to the same person. I will be sending you another blue harness.

Thank you Richard, i would prefer it be sent via Jeff, as he will explain to you.
If in the meanwhile I cut and switch the yellow and blue wires from the blue harness near the relay, will that allow the system to work temporarily or will it cause any damage?

It will be fine. I will send it to jeff, it will be full harness with thick red wire.

You can change the blue and yellow wire around to temporary making the system to work, no damage will be done.
