# 19 fuse keep poping
my under hood # 19 keeps poping as soon as the ignition is turned on. ive unpluged the reverse lockout as well as the skip shift and it continues to pop that fuse. with limited acess to wiring diagrams my trouble shooting is slow moving.. any ideas?

Check for shorts in the wiring harness under the fuel rail covers. There is a tab on the drivers side at the rear of the engine where the wire bundle rests against and can wear through the insulation. I had another short to the rail itself on the passenger side. I found the solution in some other posts that included photos while troubleshooting a fuse 19 problem. After fixing two shorts I found, fuse 19 stopped blowing.

The only places that Ive seen that develop wiring compromises under the hood of a C5 are at the back of the engine where the engine wiring harness bends around the back of the manifold:
That black metal bracket will eat thru the harness if it touches the harness.
The other place Ive seen damage is, the fuel line on later C5s has a stainless steel safety clip that fits over the connection that connects the fuel line to the engine. That safety clip has very sharp parts and can eat into a miss-routed wiring harness on the drivers side of the intake manifold.
