'98 1500 having trouble hlp plz
Hello this is my first time to the forum. My friend has a '98 GMC 1500 Suburban with a 5.7-liter engine. He was telling me that sometimes when he cranks, it doesn't start until the second crank. I just so happened to have my Bosch OBD1300 scan tool with me so we hooked it up and got the following 7 codes...
P0135 - Oxygen Sensor Heater Bank 1 Sensor 1 -confirmed-
P0161 - Oxygen Sensor Heater Circuit Bank 2 Sensor 2 -confirmed-
P1133 - Heated Oxygen Sensor Insufficient Switching Bank 1 Sensor 1 -confirmed-
P1345 - Crankshaft Position/ Camshaft Position Sensor Correlation -confirmed-
P0135 - Oxygen Sensor Heater Bank 1 Sensor 1 -pending-
P1133 - Heated Oxygen Sensor Insufficient Switching Bank 1 Sensor 1 -pending-
P1345 - Crankshaft Position / Camshaft Position Sensor Correlation -pending-
So I'm definitely just a shade tree mechanic and an amateur at that. My first guess would be that this is either a fuel pressure issue and that the crankshaft / camshaft sensor just needs to be tested/ cleaned and/or replaced.
If anybody has any suggestions please reply immediately. Thank you.
