I was cruising along the truck bucked twice and the check engine light was on, it threw codes P2149 Fuel inj. group B supply circ.open and P0204 cylinder 4 fuel inj. circ error. Anything I can do on the road if not does anyone know a good aftermarket shop in Little Rock Im stranded.

 

Take a good look at the wiring. Under the valve cover too. Can't find the post, but someone on here had an issue with it too.

 

wiring looked ok

 

As I recall his wiring was chaffed on the bottom side, not very noticable without taking the wires off . I'll look and see again if I can find his thread and post a link. He had some good pictures too.

 

Found it! Read this post and look at his problem. He points out a specific area to look too. Maybe not the same as yours, but it is where I would start! Good luck and PM me if there is anything else I can do.

Oops! Here's the link!
