I changed the follower and forgot that one #&@^ step to re-prime the lines.... Ran for a second and died.. I feel like a complete baffoon..
Take the pump back off, follower is in its bore and the HPFP "foot" is in the follower. Plenty of fuel on the LPFP supply side, the HP side is bone dry.... Cycle the key MANY times, crank and crank and no dice.. Take the HP 17mm side off and still bone dry..
WTF!? PLEASE tell me there's a bleed procedure for this.. I've searched and searched and all it came up with was TDI and afftermarket APR pump stuff.
I'll try this again here in a second..
