Looking for some thoughts or advice. Got an 08 with 191k and cranks but will not start, new batteries but also seems like weaker crank than normal. Truck ran before it was ditched and now will not turn over just cranks. Replaced all battery cables due to them seeming corroded. Checked to make sure pumps were working and definitely have fuel. Truck was tuned and deleted and I believe restored back to stock tune now. Any thoughts or ideas?
