it very well could be a fuel issue like a bad fuel filter or a clogged sock,bad fuel pump if you replace the pump always replace the filter
Hard starting, noisy pump, stalling, and finally an engine that will not start. Make sure the fuel filter is not clogged and the fuel pump relay and fuse are good.
Hard starting, stalling, noisy pump, and finally total failure.
If the relay is bad, then the fuel pump will not work.
bad fuel pump bad fuel pump
I had a '99 cabrio that had a bad fuel pump. because the fuel pump is an electrical motor, and from my experience, if the pump is bad the engine won't start at all. I had gunk in my gas tank that seized up the motor quite easily. If you have problems with acceleration or maintaining high r.p.m.s, or if the engine sputters or has poor power, you might have a clogged fuel filter.
Bad fuel pump, blown fuel pump fuse, bad fuel pump relay, or clogged filter.
Low/no fuel pressure, fuel pressure that starts out ok but fades after the engine is running a while,noisy fuel pump or electrically noisy fuel pump. An electrically noisy fuel pump may just cause interference with the radio but otherwise run ok. Fuel pump that blows the fuse. Fuel pressure may drop because of either a fuel pump or a fuel filter.
If your fuel pump is not running , it could also be the fuse for the fuel pump relay , the fuel pump relay , a bad electrical connection , or a bad fuel pump
A few possibilities could be the fuel pump relay is bad, the fuel pressure regulator is bad, the fuel pump circuit wiring may be bad and maybe the new pump is bad.
Fuel pump inertia switch tripped , fuse blown for electric fuel pump , bad fuel pump relay , bad wiring connection
Bypass the relay and if the pump works the relay is bad.
