Could it be the controller or anything else, or is it 100% the HPFP?
Worst part is car won't even limp, it just died on the highway while driving in rush hour traffic. Super convenient, super safe! I would hope that everyone that has a failure reports it to the NHTSA here: https://www-odi.nhtsa.dot.gov/VehicleComplaint/
If we don't report these problems, they won't get dealt with. An extended warranty up to 120k is ridiculous for a 13 year old car with a problem that can cause you to suddenly lose all power without warning. |
How long should the fuel pump be warranted for?
Not able to limp home also means your LPFP is bad.
The LPFP should provide enough fuel to limp as long as you stay under 2.5-3K.
I changed my LPFP and regulator about 3 weeks ago and the HPFP right after that.
I knew they were all toast, but with a new LPFP, I was able to drive pretty good as long as I didn't push it. I could even keep from going into limp mode.
If done yourself, the HPFP takes less time than changing the starter.
I was able to do the whole job including plugs in about 3 hours.
DO not remove the intake. You just need a longer hex wrench and a way to add leverage.
