NOT fuel pump relays - pump next????

[robertp]

OK thanks for the tips on fuel pump relays, thats them renewed but unfortunately still no power to pump!! I suppose I need to look at the pump next and try a direct feed, eh? So where do I find the pump and what else should i try?
Thanks again

Robert

Hello Robert,
I expect it's in the same place as a Griff, you'll find it if you take the n/s rear wheel off, should be on the bottom chassis rail in between the lower wishbone brackets. It's not your imobiliser is it? this usually cuts the feed to the pump.
Good luck.

Or a bad earth on the pump or a badly coroded connector...

Just a few suggestions before you test the fuel pump.
Check your fuel cut-off switch hasn't activated.
Try disconnecting and reconnecting the battery then resetting the immobiliser.

Chimaera's fuel pump is as David describes it on the Griff. To the untrained eye (i.e. mine) it is suprising to discover that this crap-blasted cylinder is an integral part of the car's fuel system.

Latest update - I have checked the fuel pump isolator switch, renewed fuel pump relays(2 no),cleaned terminals on fuel pump, disconnected and reconnected battery to reset alarm/immobiliser and....ZIPPO - still no power to pump!! dont even have any TVR expertise nearby, so getting real pissed off...

In my very humble opinion there are two alternatives.

One, the power to the pump is still being inhibited by the alarm.

Two, you have a break in the supply - provided you did measure 12v leaving the inertia switch (did you measure, or just waggle with a finger whilst up-side-down)??

The solution, to ensure pump is OK, is to wire a separate (fused) wire from battery to the pump - If this then works, you will have to decide on further fault finding to ascertain where problem lies, but bet its either 1 or 2.

Keep smiling.
