I have a 98 Yukon, it is a 5.7, 4X4. I am getting a P0141 DTC, the truck will crank but will not start while other times it will start. It does this with no pattern. I know the code is for "Oxygen Sensor Heater Circuit (Bank 1, Sensor 2). What would be the most probable cause for the intermittent starting?

Check the harness for wires rubbed at the front drive shaft. This could cause your P0141 or just a bad o2 sensor. Really need more info on the no start you need to find what its not getting no spark or fuel??

Usually I can hear the fuel pump but it doesn't sound like it is either getting power to kick on or just not kicking on at all.
