The checklist goes like so:
GPR. Manually check it, even if it's new to makes sure it's staying on for a long time and is getting the proper voltage.
GPs. You can ohm them out through the UVCH.
UVCH. If they ohm bad, then you could have bad UVCH connections. Check for chaffing, burnt pins, etc.
Batteries. 850CCA minimum. Good conecctions, clean, clean also. Cables good. Grounds good. Starter connections good.
Oil. For a 6.0, a xW-30 would be ok, but a 7.3 needs a xW-40. 15W-40 is normal but thick. 10W-40 is thinner when cold, but still provides correct high heat protection. 5W-40 synthetic is best. Superior cold flow and heat protection.
