Starting a 3.0L diesel with turbo timer

[rkondivers]

Just bought a 2006 GR with an Motorsports turbo timer installed. The Patrol changed into our hands while I was out of the country, so I didn't get the lowdown from the seller and now he's out of the country.

There's general confusion about the procedure to start the Patrol, and I've run the battery down trying to start more times than it's started.
I live in the mountains in the tropics. A really cold day is when the low is in the 60s F/16 C.

The owner said in the morning, when the engine is cold, to turn the key to ON for 30 seconds to warm up the glow plugs, turn the turbo timer off, turn the key off, turn it back on for a few seconds before trying to start it.

The friend who received the Patrol from the seller said the turbo timer needs to be set to 000, turn the key to ON for 30 seconds, turn it off, turn it on for 5 seconds, turn it off, turn it on for 5 seconds, start the car, then set the turbo timer to 30 seconds.

It shouldn't be this difficult so I'm sure it's a procedural error on my part that's not allowing it to start.

Would appreciate any and all advice. Very frustrated at this point!

Thanks in advance.
