reinstall the gas tank and all that good stuff, then pour octane booster in your gas tank and fill up. then crank it over. it would be a good idea to change the fuel filter also.
Yes; if your fuel pump relay fails you will not get fuel to your motor and your vehicle will not start.
A vehicle with a failed fuel pump will not start. But fuel pumps can have intermediate degrees of failure which can result in intermittent failure or low fuel pressure.
It would depend on the vehicle. If the vehicle has a carburetor, the pumping action primes the engine with fuel to help start the engine. If the vehicle has fuel injection, pumping is not required.
When a fuel pump is bad the vehicle will not start. A fuel pump that is going bad may cause the vehicle to shut off while going down the road.
wrong fuel pressure, didn't purge the line or the fuse is blown. not a OEM fuel pump?
Your 2001 Toyota 4 runner will not start even after changing the VSV and fuel pump because of another mechanical problem. Consider taking it to a mechanic.
If it fuel injected drop the fuel tank - pump is in there
Yes, a fuel pump can, sometimes, run without making enough fuel pressure to start the engine. It could also run long enough to start a vehicle but then cut out.Additional answerSure it can. For example, a common sort of pump has a diaphragm in it and if this ruptures then the pump won't pump.
I would probably think it's because you may have installed the fuel pump incorrectly or have the wrong type.
A fuel pump inertia switch is designed to shut off the fuel pump when your vehicle is involved in an accident so fuel doesn't keep pumping creating a fire hazard. If it fails in such a way that it cuts off your fuel pump constantly your vehicle will not start. If it fails in such a way that the inertia sensor doesn't work you are at a higher risk of having a fire in your vehicle in involved in an accident.
we checked the fuel pump and its good???
Start by changing the spark plugs
