Hello all,
I've just fitting my twin fuel pump set-up with individual relays. I tried hooking up the feed wire to the the Fp pin on the diagnostic port, but when connecting Fp to the battery, I'm only seeing 8 volts at the relay, which isn't enough to flick it over. The wire from Fp is really small gauge stuff, so I can understand that.
Connecting the feed to the relay direct to the battery (11volts) flicked them both over fine.
So this got me thinking is there going to be enough juice from the ECU to flick over the relays. So does anyone know what the voltage output of coil 4 is? I presume it's HS (12v) but just want to make sure.
Cheers,
