Customer Question

I have a 2002 Chev 2500hd 6.0 litre, we replaced the engine with a low milage engine but will not start. Check for power and ground at the coils and that is fine. Replaced the crank sensor with the old one from the other engine but still wont start, ( the old engine ran but made alot of noise). what else shoukl I check?
JA: Does the vehicle stall at low speeds? Does it sputter?
Customer: Wont start at all
JA: What is the model of your '02 Chevy?
Customer: silverado 2500 hd 6.0
JA: Are you fixing your Silverado yourself? What have you tried so far?
Customer: Yes, checked the power to the coil and both grounds and all have good voltage, replaced the crank sensor with the one out of the old engine, that engine was running when taken out
JA: Anything else you want the mechanic to know before I connect you?
Customer: no
