2jz fuel pump wiring

You can just use a relay off the charge light globe to switch the toyota circuit open relay, a lot of cars use this method

If not mistaken there is COR in Aristo 2jzgte. Is it tru?

NO, the Aristo has a Fuel Pump ECU, not a COR.

Below is the diagram from the other thread for the circuit I used to turn the PWM FPC signal into a trigger for a COR


cambelt has a suggestion which will also work, and is easier

Thanks for the details info

Cambelt, how do you run the COR off the charge light? Few more details to get me started would be great.
Thanks

Yes.

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

Hi All
Instead of using coil -ve, Can we use the Fc signal to tachometric relay?

You're confused I think.

In my diagram the FPC waveform (PWM from the engine ECU) comes in on the left and goes through the 1k resistor to trigger the MOSFET.

One side of the MOSFET connects to ground, the other side connects to the -VE side of the COR coil (where 'Fc' used to connect).


Yes you could use FPC to trigger a tachometric relay however.

A lot of carby cars years ago the fuel pump was switched with the charge light .
A simple small elecronics relay (not a big auto jobby as they draw too much thru the alt regulator) wired in paralell with the charge lamp , use the N/C contacts to switch the toyota COR.
