Starting issues car cranks but no start

[blackcar]

Car cranks but doesn't start. Plugged in OBD2 and no codes show up. l pressed Schraeder valve on the fuel rail there is definitely fuel pressure.
When crank is spinning the RPM gauge moves smoothly so I don't thinks its the crank sensor. I am thinking relays but wouldn't that show up on the OBD scanner?
Can someone give me good input on this issue?

Check the fuse that controls the alarm.
I once had that fuse blown couldn’t figure it out until we replaced it

When you say alarm are you referring to the chiming noise when key is in the ignition?
Thanks

Car is starting have not done any repairs. I got a hold of OBD tool and there is no codes, This is very vexing would like to know what caused the no start.
Anybody have suggestions how to determine what the fault is ? I dont want to get stranded somewhere.

crank no start with no codes most likely is the fuel pump. Ever since we’ve been getting ethanol the decline of these pumps has increased quite a bit.
You can put a fuel gauge with a 6 foot lead and put the gauge underneath your wiper and when that car don’t start you’ll notice you’ll have very little fuel pressure.
I believe two of my dad‘s cars have required fuel pump replacements within the last two years, the fuel pump went out in my blue car about two years ago
my DTR when it had about 52,000 miles the fuel pump would intermittently stop working when my buddy John owned the car. He went to the extent of putting a fuel pump driver, module and countless times to the dealer before we just replace the pump and that car is never had a single problem. It has 79,000 miles on it and it went bad. But my car was 210,000 miles got the original fuel pump in it and it’s working fine

When you get in your car and go to crank it, do you hear the fuel pump engage? Based on my personal experience, I don't think you'd get a no start/start situation with a bad fuel pump; when mine went out, it went w/o any warnings. But if it cranks that means it's getting spark and air, so that only leaves fuel not getting to where it needs to be...
