[4.3rules]

I have a 2008 Silverado with the 4.3, put all new coil and wires on it. Traced all the wires back to the numbers on the coil and to the right cylinders and now it’s a crank no start. What would cause this?

has It tossed any codes ?

are the coil/s plugged in? maybe check that at least one of the plugs is getting a spark?
