Long crank, rough idle, codes, etc A faulty hpfp can result in stalling, engine overheating, and even potential fires if fuel leaks are present I took it back to the shop and this time around (now on their dime),.
High Pitch Fuel Pump Problems – Bad High Pressure Fuel Pump Symptoms
In speaking with my mechanic he said that a faulty fuel pump could be the culprit
In your experience, what are some symptoms of a failing or faulty fuel pump
Just replaced one on a 83c When the hpfp fails to deliver consistent fuel pressure, the injectors fail to supply the engine with the necessary fuel for proper combustion This issue leads to jerky acceleration, stuttering. How do you determine if the hpfp is failing or have a pressure regulator going bad?
Over time, wear, contamination, or internal failure can lead to drivability issues The most common symptons are poor startup or a lack of power (especially under hard acceleration) The plugs/coils needed to be done anyways, but obviously i want to avoid changing the hpfp if i don't have to But i also wonder if i am damaging anything by running it in limp mode in order.
