There are a couple reasons. First what kind of car is it? It could be a relay. It also could be an inertia switch located some where. If it tripped you won't get power to the fuel pump.
Blown fuel pump fuse or defective fuel pump relay.
Check all fuses and fuel pump relay. Check the fuel pump inertia cutoff switch in the trunk.
No , it would crank , but if there was no power getting to the electric fuel pump it would not start
fuel pump relay, fuse or wires
that can be because of the fuel pump relay,a severed wire to the fuel pump or the fuel pump fuse is blown.
If you're getting power to the pump this proves the fuel pump fuse and fuel pump relay are good. That leaves only two possibilities. Either the pump is running but it's not pumping fuel. Or possibly the fuel filter is clogged.
If the pump is getting power but not pumping, it's probably a faulty pump. It's also possible that the pump pickup screen is blocked.
In order of probablility: fuel filter, fuel pump fuse, fuel pump, fuel pump relay, control system.
Check to make sure that the pump is getting power to the Neon fuel pump. Check the pump relay, and the pump fuses.
Blocked fuel line or SOCK (pickup) inside fuel tank-fuse 2 fuel pump OR anti-rollover switch that has been bumped or in a wreck.OR the hose that connectes the fuel pump 2 the pick-up tube inside the tak.or a bad fuel pump. 1st check to see it the fuel pump is getting power. If not check if power is getting to the fuel pump relay.
No. When a fuse blows it stops power from getting to the attached devices. It would power off and stay off. IF the fuel pump was attached to a self-resetting circuit breaker, then the power might cycle on and off.
The fuel pump in a 94 Lumina should not be running with the relay removed. The relay could be mislabeled, as the fuel pump is still getting power through a relay.
Check your fuel pump relay and fuse
if after replacing fuel pump and still not getting power to the pump, check the crank sensor, this may have gone bad and quite often can be the problem.
Blown fuel pump fuse, defective fuel pump relay, or loose or broken wiring.
The fuel relay controls the fuel pump, so where are the bare wires? If the relay isn't getting any power then the fuel pump will never turn on, unless you want to bypass it to check the pump. If the bare wires are going to your fuel pump relay you have your problem... if not, either way, bare wires are a problem.
CHECK THE CONNECTOR THAT IS ABOVE THE TRANSMISSION. MY POWER WIRE TO THE FUEL PUMP WAS LOOSE IN THE CONNECTOR AND CAUSED THE VAN TO SHUT OFF. I FOUND THIS AFTER I REPLACED THE FUEL PUMP.
The fuel pump is not building pressure to push the fuel to the engine so i would suggest getting your fuel pump checked and or get a new fuel pump.
No power to the fuel pump. Bad fuel pump. Fuel pump pickup screen extremely clogged. Fuel filter extremely clogged. pinched fuel line no fuel in tank
what would be the reason, i just put a new battery in car, but does not register power to headlights nor fuel pump
If you are getting power to the pump and no fuel is coming out then yes.
check the fuse to see if it is blown or replace the fuel pump relay under hood
There are many reasons for a fuel pump to stop flowing fuel. such as 1. fuel pump is not getting power supply 2. fuel pump has gone defective 3. there is some blockage in the path of fuel 4. fuel pump filter has clogged ...
If the fuel pump is not getting electricity then either the fuel pump fuses is blown or the fuel pump relay is defective.
