Fuel Pump issue

[Charlie Christian]

Hi guys

just wondering if someone can help 

I have an FG mk2 G6E Turbo running a Waldo 460 in tank fuel pump.

Im finding that when the car is in constant traffic and heats up, intermittently the engine will stall and not start up again for another 10-15 minutes until the car has cooled off.

I have tries swapping the fuel pump relay and also pressing on the inertia switch but this does not help

Has anyone had this problem and if so what was the fix?

definitely something that needs some specific knowledge, by the sound of it... I would be taking it to the place that installed the fuel pump to get them to look at diagnosing it.

Did you upgrade the fuel pump wiring when installing the 460? Potentially a wiring issue. during the 10-15 minutes can you hear the pump priming when ignition on?

No I havent

during the issue there is no power going to the pump at all

if I bridge the relay it will get power
