I would have to research it because I don't remember, but doesnt the Fitech have a fuel pump connection (as in wiring)? It it doesn't, then you need to wire the pump up so it comes on as soon as you turn the key to on. As soon as you turn the key to on, the pump should run and you should get pressure. No pressure = no start. You need to get power to the pump. Have you run through the set up on the handheld? I don't remember but there could be a pump setting in that.
