fuel pump f-up edit: pressure switch??
Turbo Mini Forums

Hi all, hypothetical question.. Because I wouldn’t be stupid enough to do this..

If you were to link the negative side of the fuel pump up to a live feed.. Then turn the ignition on is this likely to f-up the fuel pump? I thought it would just goose the relay..

Doh…

Hi,
Possible on a long shot, but it should just blow the fuse.....

fuse still intact, but the pump isnt running.. could it have done damage somewhere else? im guessing not but as you can tell im not the best at wiring!

Is that the pump being wired up backwards, or +ve feed on both sides? Because the second would cause nothing to happen. The first may blow something if there was a flywheel diode, then it may take the fuse out, or burn something out.

ummm, i guess that this happening could have nothing to do with the pump not working.... oh arse. That means that i could have a oil pressure problem.. minis!!!! could just be the pressure switch?!

i have recently made changes to the position of this to accomidate a pressure gauge. (to the last in the line on 2 t-pieces..) will this affect the oil pressure switch working?

worth a question before a take it all apart again.

cheers again.

Hi,
Just connect a pos and neg to the pump via a fuse from a battery to see if the pump runs....

just did what Gavin suggested and the fuel pump is in working order.

but not when i turn the ignition.. i will have a play with the oil pressure switch.

the pump will only run when cranking i believe if its a proper turbo setup.

i wire my in to the ignition live with an intertia switch for safety, then as soon as the ignition is on, the pump runs and in the event of a shunt it stops!

mines via a relay - and will cut out in the event of a drop in oil pressure.. i know the pump works now and its a new relay, so i guess i just need to check the oil pressure switch.
