2jz fuel pump wiring

[Omar]

Hi All
I installed complete 2JZGTE/a340E from Aristo to my R32 chasis BUT without Fuel Pump Controller that locate at rear side due to just bought `front-cut' only. I wired the fuel pump directly from fuel pump relay that locate at front fuse box.
The problem is the pump no cut off if we ON the key but OFF the engine. How to reire to get the cut-off signal if the OFF.

Thanks in advance

If you can't/don't won't to run the Aristo fuel pump controller, find yourself a tachometric relay and wire that in to turn off the pump when the engine isn't running but ignition is on.
Have a search on here/Google for tachometric relay and you'll understand what's required/involved.

Thanks mate for the info.
I will install it for safety reason

Can I use the Fuel Pump relay from BMW E36 or VOLVO 740 ?

[Omar]

Anyone please

And it worked perfectly!!!!!!!!!
Switches on primes, And turns off when it should!!!

last nite I checked the Fc out-put by using the `test light' (12v bulb) there is no out put either (+ve) or (-ve).

Thats because its a PWM output

[Omar]

so the DI should connect to ignition power (12v) than we can get PWM signal from FC pin?

[manny]

Not sure about the Aristo but the Soarer EFI ECU outputs a variable 0-5V signal at FC for the Fuel pump controller to vary pump duty cycle.

Yes.

If you don't connect DI to power, you get no signal on Fc

Yes.

Thanks willbo,
I will connect DI to power & use 2 relays to get tachometric concept as Hen's diagram.

Thanks willbo,

No, Hen's digram is talking about using two relay's to create a Circuit Opening Relay, not a Tachometric one.

They are different.
