dont get to excited over this jimbo the wireing on these are old where the pump is the wireing goe up through the boot floor from the pump to a innersia switch thats in the boot the spare wheel sits on the switch and keeps it activated if i remember correctly rip the switch out and by pass it they get rusty and fukered peugeot use a similar switch that is allot simpler and nothing to do with the spare wheel they have a re set button in the middle its there for if you get hit from behind it triggers the switch and shut the current supply to the pump any of the early pugs have them 1990s 2000 on them there under the bonnet there about two inches square on the cossie the wireing can go bad on the bit thats exsposed from the pump to were it goes up to the boot floor the rest goes up through the inside of the car via the rear pannal what i did with mine was i ran a new wire from the fuel pump relay under the carpet back to the pump some nice befey stuff and a seperate earth from the pump straight to the bodywork inside the car the ecu controls the pump and the pump gets no current going to it untill the engine is actually being cranked over i havent got the inersia switch anymore at all im not saying you should do this as well i will eventually put one in place what i did was so simple just follow the wire back from the relay under the dash i think its the black wire with the green stripe im sure its the feed but double check a heavier wire will be better it makes the system more reliable and prevents issues like you had what some folk have done is patched a volt meter into the fuel pump wireing with long tails so the volt meter can be seen when your driving take the car out and beat the holly mother of fuk into it and make sure theres no voltage drop at the pump some folks were getting less than 6volts when when diong this very enjoyable task whitch means they were going dangerously lean on fuel which means youll be beating the holly mother of fuk into your wallet for a set of new pistons and a fuking rebore if your lucky the fuel pump is live when the ignition goes on as it primmes but the other side of the fuel pump relay isnt until cranking as if i remember the signal comes from the cps that the ecu controls when i was trying to trace this i couldnt understand why it was dead
