Andrew, I'm no expert on FDs, but there are some basic things to try first. You may have already done them, if so, ignore me. Is the fuel in the tank the same fuel that has been in there the whole 6-8 months it was sitting? If so, drain the fuel and replace it with new, modern fuel blends do not last long in storage. Have you checked all your grounding points? Especially for the ECU, CPU (harness ground?), and starter. A little corrosion here will really screw things up. Check to ensure you're getting full voltage from the battery to the ECU, injectors, and coils. I believe 12.7 volts? You'll have to check the FSM on the proper voltage. Hopefully someone with experience on the FDs can better answer this.
