Crank no start

Replaced fuel pump, new coil, module, spark plugs, wires, injectors. Ran great for a few days then back to square one; cranks but does not start. Did the by pass and did the relearn process security light off did not start. Tried to do the relearn process, security lights does not turn off, 30 minutes pass still on 40 minutes passed lights stay on engine cranks but does not start and security is on. Disconnected battery for 25 minutes, connected cable back engine started let it run for ten minutes turned off. Came back later it cranked but no start.
