I would have the car towed and dealt with later. See to it that you have a freshly charged battery for the car, a healthy laptop battery and upgrade the software to latest 1.1.x to make it easier to diagnose problems. Now is also a good time to get the board checked out, it's cost effective to send the board back or upgrade/test, unless you assembled it yourself in which case it's more expensive.
Your fuse block problem is not a good sign for injector FETs if you have the flyback wire on the wrong side of it. You should verify the voltage feed to the injectors, your wiring must be off.
Long ago I used fuse blocks that forced you to use blade connectors on the wiring to attach to the fuse block, so that the connection to the fuse was through a second part in the block where the fuse was inserted.
For good reason I now only use fuse blocks where the part that attaches to the fuse is crimped directly to the wires, and I make sure that the wires can't move around much (zip tie, ..) to avoid having the fuse wiggle out and come loose.
If the car/engine has sat for a while, a lot of stuff can happen to the fuel system - what Sprocket said definately applies. I clean injectors regularly and a common problem with injectors that have sat a while, especially with old pintle-type injectors, is that they have "frozen". A short test cycle (sweep rpm/duty) usually wakes them up but the seats are potentially beyond saving and flow can vary a lot, I throw away a lot of injectors. A race car that sits during the winter should have the injectors removed, WD40/protective oil sprayed into them while held open and then put away during storage.
