A lean condition means a lack of fuel. It could be in "limp mode". How's the fuel filter and fuel rail pressure? Did the truck have a 302 engine before the rebuild?

Best Answer Mark helpful

The fuel filter is ok and yes it had a 302 before and it ran fine before!

@ Mark we have checked the entire fuel system and everything is either new or in good working condition, thats why were so stumped???

The ECU will send it into limp mode when one of the sensors is out of range or maybe not hooked up. When I was looking for reasons or circumstances that would trigger the "Safe" or "Limp" mode, I did find a forum where you might get more specific answers - http://www.fullsizebronco.com/forum

Would'nt undoing the battery reset that? Thanks for the link, I will go check that out. Did you find any reasons for safe or limp mode?
