P0089
2010 Chevy Camaro V6, 130,000 miles.
Had to shut it down on the side of the road last week when I got P0089 and P0300 (pic attached of codes). It started up later that day and ran fine. I have taken it on short drives between 3-12 miles trying to diagnose it in the days after it happened. I have not been able to get it to happen again. I am attaching a live log of high and low fuel pressures. Do the low side (fuel pumps) on these go out intermittently? I don't think it would be high pressure as that is mechanical. I can't see half the injectors going at once? https://ibb.co/J3Wb6JW Live Data.txt Last edited by MX2Forty; 10-02-2022 at 10:18 PM. Reason: Bad File Type |

Maybe the Fuel Pressure Regulator sensor is going out, wouldn’t hurt to replace it.

Are you smelling any raw fuel out of exhaust? Check the oil for fuel/smell. Looks like erratic fuel pressures on the high side. You really need a scan tool capable of commanding the high side pump for testing. I would lean toward the high pressure pump. good luck
