Late start issue

hi folks,

so just now i tried starting the car and it just cranked for like 3 seconds without starting, after that i tried again with throttle half way down cranked again without starting then i tried again and it finally started after like 2 seconds of cranking, it's quite annoying.

what are some things that could cause this?

the car has 145k miles and i changed plugs like 8k miles ago and i changed the fuel filter around 7k miles ago, cleaned the maf 1k miles ago, no check engine light

Thanks alot

I would begin the diagnosis process by doing a fuel pressure test.

i'll get on that tomorrow,

is it possible that i kinda just flooded the engine with fuel because when i started it i had the gas pedal half way down and maybe the tps just started dumping gas into the engine. (dont ask why i held the throttle lol) this late starting has happened a couple times but only when the car is hot (maybe starter gets heatsoaking?)

anyways at how many psi should the fuel pressure be?

30-55 psi.
And the system should hold pressure for five minutes, and lose no more than 5 psi.

Crank and or cam position sensors could be out. Check for any codes with an OBD2 scanner. Sensor out=car does not know where to fire on initial startup so just starts firing randomly until the motor catches.
