NA-t wont start. Immobiliser ? Please HELP

Hi guys (and gals) im in need of some help!

Ive now transferred all the buts from my old (crashed) supra which was a 5 speed hardtop na which has had a TT head, uprated intake, distributor blank.

I moved everything across from this car:

Engine,

Gearbox,

Prop shaft,

Diff,

Ecu and fuel controllers (apexi- two ecu/boxes),

Engine loom

 

I have copied everything across except from the push button starts, as both cars have their own differing ones put in... my aerotop which was an auto to start life but along the line had a TT engine in and manual box. But now has my bits in.

 

The hardtop that all the bits have come from had an alarm and immobiliser in... It has a fob to unlock the doors separate from a fob that you plug into a receiver slot that was set up in the centre console. and the key had to be turned to then push the push button to start it.

 

The aerotop i got as a bare shell. And have taken everything off my hardtop and put in this, apart from the cabin loom.

 

The push button start set up on this is a panel with a flick switch and a push button.

 

The push button start panels wire in differently in the hartop and aerotop :/

 

I have had a friend check with a multimeter that all the fuses are getting power to both sides and double check everything is plugged in.

 

The push button panel switch is getting power to it.

 

Im thinking along the lines of it having an immobiliser stopping it? Or the key having a chip? Not connecting to the ecu(s)?

 

Is it worth trying to change the barrels do the old key works it? The hardtop worked off a bare metal key, the aerotop has a platic covered key...

 

I can get photos of anything if anyone has any ideas...

 

Any help would be greatly appreciated!

My money would be on that cabin loom having your imobiliser and alram wired into that, maybe the alarm circuit isnt being completed, i would swap the cabin loom to rule that out, even though its a bit of a pain, could also be worth removing the push start for now to rule that out aswell

I was thinking of doing the cabin loom too, would it matter putting a hartop loom in an aerotop?

How hard is it to take the loom out? Do you HAVE to take the dash out or can you get to the wires and pull it out as i have all my dash panels off, most air vent platics out and glove boxes out.

 

Dash has to come out unfortunatly as its screwed to the back of the dash with clips its not to bad of a job tbh just awkward

I think you'd be foolish to pay a company to fit a new Alarm/Immobilser when it's not even running. (and I doubt if they would want to)

 

There are several things you can check . . .

 

But to begin with, you are being very vague!

 

When you say it won't start, what do you mean?

 

It's turning over OK, but won't fire.

 

Or it's not even turning over?

It's probably something very simple . . .

 

Make up a piece of wire with a Spade Terminal on the end . . . unplug the Spade Terminal wire that goes to the Starter Motor (solenoid). Turn on your ignition and then touch the other end of this temporary wire to the Battery + . . . that will make it turn over

 

Does it now start OK?

Done some digging on the net, few things i can do/try... Remove the fuse from the ecu for 30 seconds and plug back in which should reset the ecu controlled immobiliser... By-pass the fecker... Or get the alarm/immobiliser ripped out and new one fitted... Or rip the dashes out of both cars and swap the cabin looms out...

What you think?

No im still at the same point... Only thing im thinking with your temp wire theory is what about the fuel pump?
