Fuel pump will not pump fuel at all.
I check fuel pump by hooking up to the battery - Works
Checked MPI and Fuel Pump Relay - Works
Checked to make sure voltage runs to MPI and Fuel pump relay - Works
Checked that voltage is running to Fuel pump connector (main fuel level sending unit) - Works
Checked resistance on main fuel level sending unit - Good ohms
I depressurized the gas couple months ago and the car has been sitting till now. Now it won't creat any pressure
I also checked the "run fuel pump" box on my ECMlink v3 and no sound.
I have a walbro 255
Any ideas what is causeing the fuel pump to not kick on when I try starting the car.
 
Have you opened up your ECU to check for any obvious board damage? I'm assuming nothing would be wrong since it's been ECMlinkd' but I guess you never know.

Sounds exactly like what happens when the caps leak on the board. I would inspect that area of the board closely. It might of been fixed but failed.

Or link could have been installed by an individual. Dont they also just sell the chip and cable itself?

Yes the board was covered in something, almost looks like water damage, but I think the caps were leaking like hell. The link was installed by some guy at a tv shop.
