Here's the scoop:

Have a Hypertech for a 2004 LB7, been running on the top setting for sometime. Picked up our Toyhauler (15000lb), I decided to drop the setting down to 1, and maybe roll stock until I got the exhaust done. Long story short, had the trailer hooked up during programming (DUMMY), and the programmer said (interrupted). Tried to restart, and got a 7C code on the Hypertech. Truck won’t start now either, the glow plug light doesn't come on when you turn the key to start. Unplugged the batteries 8 times, nothing... Had someone from a local shop bring a Tech 2 up, he couldn't fix it either (Had 3 code 6s, and 1 code 12 on the Tech 2), even with the mapping downloaded p:eek: rior...


My question is: New ECM, or something less financial invasive? Or could I grab a Banks Tuner, and try and start over?

is it still dead?

if it is post it in the 911 emergency section, if not somebody will ansewer it here

Still dead, with a half installed Hypertech, and a 15000lb Toyhauler attached to it with a temporary in the window... Can it get more embarrising?

good luck with it, im sure somebody can help you in the 911
