2003 G35 coupe CRANK BUT DONT START PROBLEMS!!!😵😵

Hi im new to this forum thing hehe but i have a few questions regarding my "03' G35 coupe automatic transmission" i bought the car. A week ago never had rhe pleasure of driving it, i bought it with the problem that it cranks but doesn't turn over all the way. So here what I've done so far. Changed the old fuel pump with a brand new one, replace the battery, replaced both crankshaft, and camshaft sensors, o checked all the fuses from all 3 fuse box and they're all good, checked the grounds on the Motor, rested the ECU i went out and bought a new one also just in case it needed to be replaced, had a brand new key programmed and made for it, and still NO START has anyone had this problem before? Can someone please help me out with this problem before I just junk it!!!!!😵😵😵😵😵😵😵😵

What does the security LED do while cranking?

Typically having the vehicle towed to Nissan for a 1 hour diagnostic is a lot cheaper and easier than throwing random parts at the car hoping something will work. Usually it's $125 for the 1 hour labor charge plus $75 for a rollback tow truck. If you have AAA it will cover the tow truck.

I would hook up an OBD2 scanner and check for hidden codes before and after cranking the engine. If you used aftermarket cam and crank sensors then there's a decent chance that they won't work. Use only OEM Genuine Nissan Parts or Hitachi (the OEM manufacturer).

Since the vehicle has NEVER run I would also do a compression and leakdown test to verify that it isn't just a blown motor before throwing any more money into it.

Does the security indicator flash when you arm the system with the fob lock button?

Does the SES light on the dash illuminate when you turn the key to the ON position?

Lift the back seat (two plastic tabs that you pull forward, then lift the seat cushion up from the front) and make sure you can hear the fuel pump prime.

I'm betting there's some codes stored that will tell you the problem.

When you got the key programmed, you either took the vehicle to the locksmith or he came to you and plugged into the car and programmed the BCM correct?

Did the previous owner give any history about the vehicle or any hints about why it stopped running?

The previous owner told me that a week before he was driving home and the car just turned off and since he got a brand new car he didnt want to waste his timw fixing the 03 g35. The SES light doesn't come on at all .. and the security light doesn't stay on at all when it on the on position.. and the fuel pump primes perfectly fine.. and yes the locksmith came out to make and program the car keys.. any other idea of what can it be ??☠️ Thqnks for reaching out 👍🏼💯💯💯
