The problem I'm currently facing is regarding the fuel pump not priming, the engine will turn but will not fire up. I experienced this last year (in this thread - http://forum.205gtidrivers.com/index.php?showtopic=151681&page=1 ) but the fuel pump priming issue went away when I replaced the relay. The car then sat for a few months through winter, then a few months ago I replaced the battery and it fired up instantly. I then sent it to a bodyshop for bodywork repairs and painting. The car has been in the hands of the bodyshop for some time and they reported the car had been starting fine (they had the car for the last few months) but then recently the car started to cut out 20 seconds or so after starting, shortly after the fuel pump completely stopped priming. So far I have: Checked the Inertia Switch (now bridged). Tried two different Fuel Pump Relays, both verified as working 100% on another GTI6 205 (Dobboys). Checked the Fuel Pump Relay socket female connectors (all ok). Bridged Pins 5 and 8 which did indeed result in the fuel pump audibly buzz/prime (ruling out fuel pump failure?) I am stumped as to how the fuel pump primes when I bridge pins 5 and 8 yet it won't prime when I fit either working relays? Dobboy suggested checking the relevant relay pins for 12v readings which I will do tomorrow (the left coloumn of pins of No.40 Engine Management Relay just below) in case there is a broken bit of wiring leading up to the terminal itself: It's a real kick in the arse seeing as the car is finished and looks great but now it's stuck at the bodyshop! Is it at all possible that there is a bad earth that could cause the fuel pump not to prime? I'm slightly worried the ECU may have somehow locked itself as well. Appreciate any advice.
