LB7 glow plugs?

[bwboley]

Just changed out my injectors but our temps have dropped below freeing into the teens, when its that cold my truck cranks and runs rough for few secs then runs good. or when its warm it has no issues either

The wait to start light come on and stays on then turns off like before also no CEL

I check the relay [if thats the box on the driver side of the truck] and it did get hooked up again.

anyone have any recommendations to check?

If it is a federal emissions truck, the glow plug diagnostics is basically nonexistent. Grab a multimeter or test light and make sure all 8 glow plugs are working.

You can check your intake air heater as well, but unless it is REALLY cold, it shouldn't need it to run smooth on a cold start.

Also make sure you got the crossover wire reconnected at the front of each rail. Glow plugs should be changed out every 75-100k miles as they are maintence items, just overlooked by most.
