R32 Gt-r Will Not Start

[justinfox]

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!

try crank angle sensor, or posibly the igniter

thats the fuel pump control modulator

thats the fuel pump control modulator?

Ah nice one!!! Good to know, so it's definitely not something I can take off then!

first thing i do when ever a car wont start, check spark then fuel...if there are these it will start.

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!!!

Maybe next time you'll find out what it does BEFORE you remove it.

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.
