Throwing parts at the car hoping one of them will fix the problem is not the way to go. I would demand my money back from the so called mechanics that replaced a bunch of likely good parts without doing a correct diagnosis to find the real problem.

Verify the EEC is powered up in start and run. Verify fuel pressure is correct during crank. Verify injector pulse during crank. Verify coil pos terminal has 12 V in start and run using a test light. Run KOEO codes to verify no sensor is disconnected, and sensors are all within expected range. This should not be a hard problem to solve!
