fast efi problem

I realize that when you talk to FAST's tech support it doesn't seem to help much. They will be pretty adamant about keeping all of the wiring as far away from everything that could cause interference and they will tend to emphasize having perfect connections on everything. When we've had problems with ours it actually did turn out to be connection issues. - Insufficient grounding or the need to reroute wires. We had not soldered all of our splices because we were having to play around with wire routing. Twice already, we've had issues that involved having to go back and solder connections.
