I don't have many problems with the pump now, just 2 running codes. I know I'm beginning the early stages of pump failure, so should I rebuild or replace? The old ODO says 196xxx miles. Truck is a bit long in the tooth. It's had a hard life and I know nothing of the maintenance on the motor in the past. Other than the green tag, I can't say much. What's your opinion? Finding someone to do the work may be a hassle as well as the guy who changed my headgaskets has retired(as far as I know). Changing the pump may not be all that bad, but resetting the timing and computer I can't do. Is there a source for ip's? I know new they are $$$$$$$$$$$$$$$$$$$$. Is it worth rebuilding or should I just get one that's already rebuilt?
