Defective fuel pump fuse, defective fuel pump relay, loose, corroded, or disconnected wiring. Lastly, the new fuel pump may be defective.
Fuel pump fuse or relay are bad.
i know that sometimes when a fuel pump doesnt work its not the pump, but rather the fuel pump relay try checking that
yes if you need new fuel pump, the engine is not getting fuel. therefore no fuel equals engine wont run
Could be a bad connection to fuel pump. Many fuel pump replacements recommend a new wiring harness for pump. Also, some aftermarket pumps have a different plug from original and require a re-wire. An old plug on new pump may have shorting issues. Make sure pump works constantly when running, and does not intermittently shut off. Should have steady hum from pump.
You need a new fuel pump
that means it is working properly... nothing to worry about....when you no longer hear the humming sound its time for a new pump
most likely you have a defective pump also make sure you change your fuel filter if that is plugged that will kill a pump fast
If the pump is new, the most likely cause is a clogged fuel filter or line. Broken line, cut hose, improper instilation.
Remove fuel filler cap - turn on ignition and listen for "hum" Check fuel pressure - with key on engine off should read 23-31 psi.
If there is fuel in the tank and it is making it's way to the fuel pump, and the fuel pump will not pump fuel, the pump is obviously defective. Replace the fuel pump with a new one.
broken fuel pump/ fuel filter can cause car to die right after starting. If the fuel pump is not pumping fuel into the engine, the car will stall.
Check the fuel pump relay
