GTI fuel pump relay 8V K jet ?
« on: 26 June 2016, 18:12 »
OK so i believe the fuel pump relay has given up...well to be fair it is 30 years old

i have no priming of the under car pump (which it used to do on starting up ) the fuse is good 
as per the haynes manual , i have feeds to the relay base but nothing to the pump
the sparkplugs are dry so no fuel getting to em..
so i hope it's just the relay & not the pump as well  :sad:

Turn the relay upside down. If it primes then its the relay. If not the pumps gone

Ive had ce1 k-jet it should go in another way and bridge the connections to make the fuel pump prime. As to check if the pump works still.

Or put a power to the pump underneath and see if it primes. Again eliminates pump
