Gtr won’t start. Help!

[GtrMosh]

Hello everyone!

After stupidly having my Gt-r sitting in the garage doing nothing for about 2-3 years I’ve tried to give it a run. I changed the oil and oil filter and tried turning it over with no success (surprise surprise). My battery is fine and it’s got fresh fuel. 

As I turn it over I don’t get any oil pressure on the gauge, is that expected? Will I only get pressure once it starts? Bit of a noob tbh. I’ve read that the gtr oil pressure sensors are dodge city, could that be stopping it from starting?

Im going to check for spark but I’m worried it’s full of sludge. Can anyone point me in the direction of a good mechanic in Sydney’s south? 

Any help is appreciated!

Thanks!

Shouldn't see oil pressure on gauge while cranking.  Is the fuel pump priming and stopping like it should when you turn on the ignition?  If not, could be dead/seized from inaction.  Injectors could also be stuck closed.  Does it fire in any way at all, or just cranking with no chugs?

Ok cool, that’s a bit of a relief at least. Yeah the fuel pump primes when I turn it on reds as expected. Doesn’t sound like it’s firing, just cranks on the starter motor, I need to check for spark right? Does the ecu rely on the oil pressure sensor to start? I also thought it could be the ignition module since that’s gone on me before but after buying a new one I tested my old one and it was fine (face palm).

No, ECU does not watch the oil pressure.

Could be spark, but could also be fuel - see my point about the injectors.  They do get gummy.  Sitting for long periods lets the gum harden.

Yeah sweet I’ll give the injectors a once over. Cheers dude
