Power loss after switch?

[Landcrawler]

So I recently removed the self leveling suspension in the rear and put a lift in. Afterwards, if the car sits for a few days, it becomes difficult to start. More than a few days and the truck wont start. After I jump it, the battery and entire charging system all test fine. Any idea's? I have to think it has something to do with the removal of the rear airbags/self-leveling suspension since I didn't have this problem before...

The SLABS ECU is still trying to level the suspension (lower it). You have to turn off the air suspension in the SLABS ECU to fix this.

Thanks. I kind of suspected something like that. The SLS light came on for a brief moment a few days ago.

Anyone with a Snap On scan tool can configure it for coil springs, so most independent shops can do it. The dealer can do it too, but it will likely be more expensive.

ok, thanks.

I pulled the under hood fuse and unplugged it at the pump, haven't has any issues other than the light on the dash so far. I have let it sit for a couple of weeks and started just fine. I will eventually get the scan tool to set it but this helps in the meantime.

I may be wrong, but doesn't that cause the three amigos?

No three amigos, and just replaced the shuttle valve.
