Fuel pump not working off relay board

[Organdonor]

I'm currently trying to run MS11 - V3.0 with relay board from DIY Auto tune. I have not been able to get the fuel pump relay to put out a signal, either to prime or run the fuel pump.

 

At this point I've gotten the car to run by wiring the fuel pump directly to the ignition hot wire.

 

My directed question would be - is there something in the programming that needs to be set for the fuel pump relay to put out a signal, or perhaps something to look for in the actual hardware? Thanks in advance for any light you can shed on my hiccup. Renn

Unless the firmware is corrupted, the relay should not shut off entirely. Does the fuel pump LED work on the Stimulator?

Thanks for responding Matt, I don't have a stimulator, but was able to check at different stages of the assemble process with a multi-meter.

 

In trying to trouble shoot the problem I put a multi-meter across pin 5 of the relay board and ground and turned the ignition key to on and cranking position. It showed 0 voltage to prime the fuel system or during the cranking process.

I also did a continuity test from the #5 pin all the way out to the big connector to MS2. All three led flashes on initial start-up. At this point I'm suspecting something I haven't set in the programing or some parameter thats too far out of whack.

What area should I be looking at in the software, or the MS2 board itself that might have an effect.

 

Also,sorry for the delayed response..., 12 hour days at work : )
