Hello,
setup Fuel Pump thru Relay, board default (should be Pin24).
Power on, Fuel Pump not running. Test Output Hardware, Injectors are working, but no fuel.
Am I correct in understanding that Fuel Pump should be working immediately after Power Up, or how can I test the Fuel Pump. Is there some kind of Output Test function for Fuel Pump?
Trigger not hooked up yet.

Hi Jochem,

This should help if you don't already have it: https://github.com/turboedge/SpeedyBoar ... ctions.pdf

It should prime with power on. Is the board type set to UA4C? The fuel pump is pin 23 on the arduino. There is an LED on the board that should light to let you know its working. If it is not and you want to check the circuit you can jump 5v to pin 23 on the arduino. That will trigger the output manually.

accoording to the document, FLPUMP is on 24....Tacho is 23...
or am I missing something here?

Rather embarassing....
I somehow made the assumption that FuelPump is a voltage output....corrected the wiring on the relay....

For anyone else reading this...

ALL Speeduino outputs switch to GND other than the Ignition.
