OK i picked up a bosche 910 fuel pump 2nd hand about 6months ago but have only got around to installing it now. I have setup a 30amp relay triggered from the ecu and then used 4mm wire to the pump. With the relay switched on I get 12 volts from the battery (with ignition on aswell).
Problem is the pump doesn't do anything. I can hear it click on and it gets hot but no pumping. With the car running im only getting 13.1volts to the battery instead of the usual 13.9-14volts. So it seems its drawing a lot of current (hence getting hot) but yet it refuses to switch on.
I did however get it to work by connecting it to the 12volt battery charger which i assume puts out about 14-15volts. Its pretty loud which is expected.
Oh and another thing the pump is mounted external but it isn't pumping fuel yet (fuel lines not connected yet) because i want it to work before I got chopping up my fuel lines. So will it make a difference if the stock pump is supplying it with fuel?
Or is it a total dud in which i need to buy another?
Cheers
