I have a 2001 dodge Durango 4.7.
It will roll over but won’t start. Changed spark plugs, cam sensor, fuel pump, still nothing, and now it builds too much pressure and blows oil cap off. What could the problem be?
At least one cylinder has bad rings. That’s what’s causing the oil cap to blow off. The PCV system could be at fault but my money’s on bad rings. What was the condition of the old plugs?
