R33 GTS : Shuts off after 3mins?

[blink182house]

So I've been tinkering on this customers R33 for some time, looking for any inputs, I'm stumped.

Car had a aftermarket japanese remote start which I believe had a built in turbo timer. Its an OBDII R33 GTS. I have removed every aftermarket component thats electrical and unplugged a million different things on a guess. Also changed ECU, changed MAF, changed coolant temp sensor. Car will run perfect, starts perfect, runs for about 3.5 minutes and immediately cuts off. Will start RIGHT back up perfect. Does the same thing each time.

Any ideas?

I have removed all the interior and dug around in the dash for hours, there's nothing left that's aftermarket. Wiring on oem plug for ignition switch is untampered.

Triple check that there is no turbo timer harness hooked up under the steering column or in the column casing, that's where I found my turbo timer when my car showed up from Japan. A buddy of mine also had a turbo timer hooked up in his rhd s14 that would turn on with the headlights and that would make it go haywire. Most of our skylines come with some jank wiring so I would pull all the under sides of the dash off and the kick panels, you're bound to find something.

Yeah every skyline I get in I end up filling the trunk full of garbage electronics and wiring lol! I removed the remote start that has a built in turbo timer, the harness was a sub harness on the ignition switch on the column. I've laid under the dash for hours poking and unhooking stuff and no results! It HAS to be some sort of ignition cut, like a timer, but I literally have found nothing on the car that remains aftermarket. It's killing me!!!

Have you pulled ECU Codes?
