Technical No power to fuel pump

Zubair · Feb 7, 2016

Hi guys

I've had a huge issue as i tried to start my panda 1.2 and the pump didn't work, i tested the pump an its fine, i ran a direct line to an ignition+ to check but now the pump goes on with my mechanism but no fuel gets to the throttle body to start and the pump pushing as normal, please help had this issue for months now with the car, please what else can i check as well as my fuse cover does not say what relays or switches can be an issue

Cranksensor not telling your ECU that the engine is turning and cutting out fuel.

Hi,
without going through your previous posts..,

the main reasons for the pump not running;

FIRE prevention cut-off switch - under seat

Immobilised - symbol on Dashboard

electrical supply - power OR earth

:idea: IF it's "locking- out" the fuel supply , you by-passing the pumps power MAY mean that the next part of the fuel system is NOT enabled either

I've never seen mention of a fuel pump power supply fault on a panda.??

it SHOULD run for a few seconds - to pressurise system - BEFORE cranking begins..

Under bonnet is the injectors..

You want to hear the fuel pump in fuel tank. Lift up rear seat to hear it better..
