HPFP End of Life Tell-Tale
Is there a tell-tale that the high pressure fuel pump is near end of life? We know the timing chain is about done when we detect cold startup rattle. Is there something similar for the HPFP? My chain is pretty new, but I stuck my head under the hood the other day and might have heard my HPFP rattling on startup. The pump has nearly 200K miles on it. The engine runs fine and has no CEL, but I don't want to get caught off-guard and stranded.

That rattle is likely the phasers and not the pump.

Nevertheless, I'm curious if there is any tell-tale that the HPFP is near end of life. |
Mostly much more noise, lower fuel pressure readings on the RPD screen
some info from the Cobalt site https://www.cobaltss.net/forums/2-0l...issues-289987/ |

I don't have an RPD, but would be interested in buying one for a great steal! :wink:
You could run a good bluetooth dongle and the Torque app on your phone or tablet. Should even be able to do some things the RPD can’t. Should be a real ELM327 or better, crappy clones will run too slow to give good really-time data. I have the RPD and still use an old phone dedicated to OBD apps, and an OBDLInk LX. |

The car has a sensor and will know if the fuel high pressure is low even if you don’t have an RPD.

I think "torque lite" is Android only unless something changed. But there should be others search "obd".

I have Car Scanner ELM with the Vepeak obd2 reader. Works great. Got the Vepeak off walmart.com for $10 less than anywhere else, $6 for the App
