After the truck sat overnight, when cranked it would just turn over normally without any sign of starting. So, new oxygen sensors were bought and installed, figuring that 185,000 miles was about time to go ahead and replace both of them. This did not solve the problem, as the engine just spins over (sounds normal) but there is no attempt to fire off.
This truck had 1 prior event of failing to start about 5 years ago. During that ordeal, no code reader was available and both the cam and crank position sensors were blindly replaced. The problem was the cam position sensor. The distributor cap & rotor were replaced during routine maintenance shortly afterward. IIRC, that all happened somwhere around 90-100K miles. The platnum plugs have been in since about 50K miles.
Wondering if it is possible that a failing O2 sensor caused an over-rich condition which may have fouled all 8 of the old plugs or if there may be something more sinister going on. Repair resources are extremely limited at my current location (there's 1 NAPA store) in a one-mechanic town.
have the same problem?
