Check for fuel pump operation and power at the injector, each has two wires, one is ground, the other will be hot when the key is on. These should be energized by a relay, so check switched power to the relay, inline fuse, etc. Each swap is different, but if it was done even remotely right, there will be a fuel pump relay and another relay, or maybe more, for everything else. Some people bypass the oil pressure switch, I didn't, so if the motor loses OP, the fuel pump quits. You can check that by using a jumper wire if you still have the OP switch. The FP relay powers the pump momentarily at start up, independently of the oil pressure switch. Anyway, some basic tests and you should narrow it down pretty fast. All these parts are almost spilling over the fence at any wrecking yard.
