[Vwdiesel] An off-topic, but Diesel question (fwd)

[Roger Brown]

I almost had that happen in my 4x4.  It uses a secondary winding on the fuel pump relay to 
turn on the electric fuel pump while cranking the engine over.  Then once the engine 
catches, the air flow meter has a contact that closes and keeps the pump running.  Mine 
had quit working one summer.  Luckily the factory provided a test jumper where you can 
turn the pump on and off with the ignition power.  I hard wired that jumper for a while, 
then thought what a brilliant anti-theft feature, just run a hidden switch to that test 
jumper.  I did that and the once "broken" relay winding started working again and has been 
ever since.  So I was happy the problem was fixed, but bummed that my cool anti-theft 
feature did not work.  I did leave the switch installed in the engine bay just in case the 
relay starts acting up again:
