The key ignition switch will not turn to start the engine

New fuel pump and still not crank

The car want crank and was accelerating bad n shutting off

The battery has been replaced as well as the starter, fuel pump and fuel pump modulator on my 1997 Infiniti Q45. But my car still only cranks but it won't start, just acts like it wants to. I've also tested the relays as well. The only codes that pulled up was for the modulator and a knock sensor code. Which way do I go now, I'm kind of at a loss.

Changed fuel pump, crank sensor, fuel pump control module. I could crank over and over but wouldnt stay running now I cant try cranking more than once it acts like battery is dead after the first cank.

Fuel light stays on constantly

Has a new battery and still cranks but won't start and has no rpm movement. Checked for spark on one of the coils and have no spark, i also checked the fuel pump modulator and it tested good. The fuel pump turns on when trying to crank the car up, but still won't start at all. Any suggestions as which way to go next. Also codes for the Knock Sensor and Fuel Pump Control Module pops up. Thx-

Because they need changing

Changed all ignition coils and plugs, but idle's rough and will hesitate big time 45-55 accleration. Timing chain so says don't mess with that? ..(i have 200k miles)...whats next? Is there a timing adjustment I could perform or is that a complete new chain, (2K?)...thanks for any help...Bam
