death of a fuel pump
In days-of-old, external fuel pumps were gone when the diaphram deteriorated and fuel would not enter gas lines; engine made a distinct sound of bogging-out; pump leaked. Dead and gone.
Q: Some have said I have a bad fuel pump (probably caused by improperly storing car with low tank and no stablil) in my '98 Z3, 1.9 because my car intermittently stalls out while starting, stopping and driving - it backfires too. If it's the fuel pump, how could I have gone through two tanks of gas. When is the pump dead?
Can I test the fuel pump from the top of the vehicle w/o special tools? My pump is in the tank which needs to be dropped to access. Hence,
can I disconnect a line and turn car over to see rate of flow (30 oz in 30 seconds)
Can someone tell me where the fuel regaltor is on March built '98 Z. The manual I have does not show picture of my engine. It show a regulator at the end of the fuel rail- I don't see a regulator where shown. Can a fuel reg be tested w/o special tool?
To date I have changed the fuel filter, air filter, checked top side vacuum lines, and cleaned plugs. I may need to check plugs again as I have driven 500 miles under fault symptoms.
