2LTE Mechanical Injector Pump (Non ECU) | LJ78 ATM

[nomadtribe]

In my endeavors to get my LJ78 running, I am considering what it will take to bypass the ECU for the Spill Control Valve and Glow Plugs.

Question - Will a mechanical injector pump work on a 2LTE Automatic? From reading other posts, manual seems to be no problem, but not sure of an automatic.

For glow plugs, I will be going with a manual Wilson switch.

For temp gage - will be wiring this into the front dash and bypassing ECU temp sensor (if possible to bypass?).

Is there anything other than above I need to consider to bypass the ECU when getting the engine to run? Note - The ECU will still be connected to provide the relevant integration with the dashboard features.

Greatly appreciate your wisdom.

Unfortunately I can’t actually give you any answers, except it looks like I will be giving a similar think a try (I have 1kz swapped my LJ78 automatic but having EDC issues so I’m contemplating a 4m40 pump swap.

Nice. I have been exploring this a bit further, but unsure what needs to happen regarding gearbox management. Seeking to find if this is controlled by the ECU or vacuum pipes mounted near the top of the firewall.

2LT-II into Auto LJ78

Since I bought my truck, the rear two cylinders have had a bit low compression. This is due to the previous owner in Japan letting water sit in the rear cylinders back when the head went. It rusted and pitted them. I was able to drive it fine since I bought it, but now the damage is starting...
