R33 Skyline Won't Start =/

[Jms-777]

hey guys i need some help here,

never had a starting issue in the year ive owned it, i drove my r33 all day running fine started up fine threw the day drove normal turned it off to filled it up at a Caltex service station (98 fuel always) went paid came back out and the bitch wouldnt start....ended up clutch starting it and it ran fine no issue got home parked it... next day went to drive it and still not starting atm

cranks over fine, tried jump starting it it just cranks even faster, i can hear the fuel pump priming loud and clear, i changed the spark plugs ( BCPR7ES ) the ecu lights up as normal everything...

im losing my mind fml.

Could be a few things. Could be an injector issue or a spark issue or an afm issue. Start by geting an old spark plug (if you have one kicking around) and unplugging one of the coils, plug in the spare plug, make sure it's earthing in the motor and have someone try and start the car. If you can see the spark plug sparking, then it's most likely not a spark issue.. also listen for the sound of the injectors ticking. You could do this before checking for spark. No injector tick and no spark would both lean towards a dodgy crank sngle sensor.
