Fuel Pump relay! new Fuse board needed?

Hi all,

So car just started cutting out so from info on here worked out fuel relay.
got a new one and went 100yds cut out waited 10mins and started.
thanks to Briano told me about how to test, what I would say never in my 10yrs of having the car had I heard the buzz noise when the key turned but I did with the new relay.
So today did some tests drove 100yds car stopped put old relay in car started drove 100yds car stopped again since then about 4hrs car wont start with either relay on new relay I still here the buzz kick in so it is not the relays. also put number 8(17 on my pics) relay in number 2 and buzz noise again but this time didn't stop but still wont start.

I have attached some pics incase I am missing something do I need a new fuse board?
Please help going to take it to the scrappy soon!!!!  

look at cabby-info.com she has a pdf on the internals of the fuel pump relay, some of the after markets have the wrong internals and act wonkier than hades.

I gave you the horn relay swap to eliminate the fuel pump relay did you that do swap and drive it to eliminate the fuel pump relay as the issue.

Use No 17 relay below the fuel pump relay to check if the pumps run with the ignition on or get a bit of chunky wire and bridge the 2 larger connectors where the fuel pump relay lives and the pumps should run even with out the keys in the car....

Hi I put in relay 17 and the relay clicks and the ignition module continues to whine, that would tell me the relay is faulty.
The no 2 relay and the replacement topran is now no longer working I suspect yesterday they burnt out the relays appear to be over heating.
My relay number 2 is 321906059d the replacement that topran sent was 103 420 755 says on box replacing 321906059f so I will have to find a 2nd hand direct replacement for the 321906059d
Think I still me to try the wire trick? As I am sure it's the relay I hope so it's driving me nuts
Thanks as always

Okay guys bit of an update.
Tried the wire trick and I can hear the pump kicking in. However I also tried the faulty relay and it started the car after 2 days of not starting it does that make sense.? I imagine if I took it for a spin it would just stall as it appears to over heat.
Still going to buy a new fuel pump relay and decided to replace number 17 (8) as its getting very hot and shows signs of water damage.
Hoping fingers crossed that does it but my MK1 has been a test from god and hopefully I get some luck….

I would have a look in the fuel tank and check the lift pump filter is clear, (not sure what year your car is as early cars have no lift pump in the tank)and the fuel tank is not full of bits of rust etc, you can get into the fuel tank from underneath the rear seat.

It could be you have a blockage somewhere and the fuel pumps are struggling to pump the fuel hence the fuel pump relay etc gets hot as it needs more power to run????

thanks I have a mk1 1983 1.8 GTI, when this all originally happened I thought it was the fuel filter blockage but will replace this also as the heat on the relays is a concern.

cheers again

Did you look I the fuel tank at the intank pump under rear seat. Mine last week was shuddering underload..turns out my 2 silicone hoses are rotten and affect fuel flow. So need to source new fuel silicone lines in the tank between sender and pump. Lift sear out and take a look. Could be pump which is 20£  

Hi thanks for the info, my sender doesn't have the rubber hose's I did take a look in the tank it was clear as day no signs of rust.
Ordered a new fuel filter will fit tomorrow see what happens. Going to be a process of illumination I am afraid.

thanks again

When checking inside the tank just don't use a match …  Won't get further illumination that is….

The 84.5 Cabriolet CIS is when they started to use in-tank pumps as they went from a 10 gallon to a 13 gallon tank.

Gave myself a couple of days to calm down!
Wait for it after all this it seems the clip had fallen off the Hall sender and it was coming loose forcing the car to stall. While the car was running moved a few wires and it cut out traced to the Hall sender and bingo! well I have driven it a few miles without it stalling so hoping I cracked it.
Also sent today fixing the washer pump as it wasn't working thanks again to this site traced back to connector not touching on stalk. Another problem solved
Going for the rear wheel bearing and oil leak this week.

thanks again for all your help for the moment me and GTI are back in love! lol

whoo whooooo
