Fuel Pump Relay (1990 1.9 205 Gti)

where the hell is it?

 

have a very odd problem with starting the car, it wont start on the key but will bump start, and sometimes disconnecting the battery for a few seconds will let it start on the key again. There is no voltage at the fuel pump when i crank the key so i think it's relay but how can it bump start?

its next to the ecu , under the dash , above the throttle pedal next to the steering column .

 

(please don't double post in other forums)

thanks, you're a star

 

sorry for double post, couldn't decide what would be seen first

think i've found it, not sure i've got the right one i can't find the right wiring diagram but the pin numbers on the one i've got are 87,87b,1,15,50,30,31

 

pin 87 is scorched, so i hope i've found the problem, is this the Fuel pump relay? i've opened it and it's a circuit board with a coil

i'de recognise it more with wire no's rather than pin no's . 112(a or b also) is the tacho signal , 1 i think is a main ignition ?, definately 76,76a is there (fuel pump feed in and out). it does sounds like the one , its taller than a normal relay.

afaik you can connect 30 and 31 up to run the fuel pump constantly to see if that is the problem, but DONT do this unless you know what wires your connecting up, the haynes manual wiring diagrams will tell you this.

replaced the tachymetric relay and it still doesn't work, could these be any more damaged relays or anything else likely to have done this?
