2006 Thomas starts but won't gas or fast idle
We have finished a roof raise on a rear-engine 2006 Thomas with air ride. The emergency doors, AC, and lift door were taken out.
The bus starts but the gas pedal is now unresponsive. It also will not allow us to switch into fast idle.
Is this due to the interlock system many buses have? Or something else entirely.
Has anyone else experienced this?
Thanks in advance,
