R32 Gt-r Will Not Start

Hi guys,

GT-R's been 100% fine. I have a completely DEAD battery due to the car being in the workshop for afew months, but a very strong battery jump starter which I have been using to start the car up for times when I need to move it.

I was doing a few things the other day:

1) Replacing the 180km/hr cluster with a 320km/hr cluster.

2) Putting back the plastic panel over my Power FC ECU.

3) I removed a unit/box that looked like an ecu thing which was found behind the driver side rear 1.4 trim.

And when I went to start the car up, it cranks but the engine does not fire up!!!

- Immobiliser wires have been checked, and immobiliser seems to switch off (red light turns off when de-activiating it). Car cranks so this means it's not the immobiliser?

- I put the ecu/unit/box behind the driver side rear 1/4 back in. I still do not know what this unit is. I thought it was a stereo AMP or something?

- I took off thw plastic panel over the Power FC ecu and checked all wires in case I damaged something back there, everything seems fine.

- Replaced spark plugs just in case, everything seems fine.

- Checked fuses, do I check every single one of them?! The ones I did check under the steering wheel, seem fine.

Car still will not start, cranks and cranks but does not fire up!

Any suggestions would be greatly appreciated. Really confused!

Guys it was this little unit which godzl1975 pointed out as the fule pump modulator. Plugging it back in wasn't enough, we had to re-mount it on the chassis before the car would start! IE: It had to be properly grounded in order to work. Amazing how such a silly small thing stopped the whole car from starting and caused us to do so much head scratching, not to mention taking the dash apart, ECU and replacing spark plugs!!! :)

Yeah i unbolted it but left it plugged in (can't erember why but sure enought he car wouldnt start till i screwed it back down. I 2nd the statement about removing things after you learn what they do. Many people under estimate the complexity and technology built into these awesome machines.

      Jacks that fit under GTR lips that can reach the subframe?

      I read this and thought "ah! I will do this scissor jack on the tow point thing!" I just use my floor/low profile/costco jack and lift the car up by the tow hook itself, then slide jack stands under. Never thought about using scissor into floor jack combo :p

      Well, my new WMI system took much longer to finalize. I actually missed my dyno appointment last Friday and lost my 150$ deposit. I'll be going back in the next week or two.  To sum it up. I only kept the AEM tank from my old setup. I replaced the AEM pump with a higher flow/pressure ProMeth 30GPH pump. I also swapped over to a 6AN low pressure feed line to the pump from the tank. There's also a pressure switch you cannot see on the pump high pressure line.    This is feeding 6x 200CC direct port nozzles and 1x 500CC Pre Throttle body nozzle. All fittings are Swagelok, because well why not. I also have a 300PSI pressure sensor up front.    I now have my Haltech ECU controlling everything. I start my pump with a basic relay at 5PSI and deadhead it. I then PWM a 3000CC methanol Injector to control flow starting around 10psi. The pressure switch in the trunk, along with my tank level are safeties before I ever get to 10PSI, and then I use my pressure sensor upfront as a secondary safety to cut the WMI and corrections in case the injector blocks or a line ruptures.  Wish me luck on the dyno!

      So, I'm back with bad news. There's no jack long enough on this planet that will reach the front subframe. If by some chance there is, it would weigh 200lb's.  I purchased a long reach jack... The damn thing weighted 120lb's and was massive. Didn't even come close, was still short at least a foot. It was a pain, but I brought it back. Next I decided HA! No problem, I'll get an Extra long reach jack. Well, I couldn't lift the box... It must have weighed 160LB's and luckily there was an open box in store. I took measurement and was still nowhere close.  Sadly I've lost hope and have accepted defeat.

      J50 clock date suddenly reset to January 1

      Thanks for that tip, niZmO_Man. I think the battery is OK. It's quite a new one, but I'll check. Last time I needed a new battery, everything electronic was fine, except that there wasn't enough current to turn over the starter. I decided to order one of the partial AV system translation CDs from Car Audio Workshop in NZ. That might have some effect, or help me diagnose the date problem. 🤞

      I suppose it was relatively stock too, the JZ motor handle most mods thrown at them without even breaking a sweat
