Turnover but no start!

2007 tacoma 4.0L automatic trd sport, became hard to start and now won't start at all. Replaced fuelpump, circuit opening relay, efi relay, mass airflow sensor, crank sensor and nothing. Fuel pump isn't turning on with switch, straight wired it and the pump worked and was pushing fuel. Still wouldn't start. Could the imobilizer in the ignition switch keep the fuel pump from turning on? Or could it be computer related?

 

So you jumped 12v directly to the pump and it works, you should find 12v from the fp fuse and follow the circuit till 12v is not there. Or you can start from the fuel pump and back track till you find 12v, either way works but i like to start from the fuse.
