Pump starts then stops within a second. MKVI GTI - HFS-4

[maskari_gti]

Hello everyone,

I've had issues with my setup not long after getting it all set. Tuner/workshop is 500kms away from where I live so I can't just drive there whenever I face problems.

It started with leaks from the elbows, bad installation of the nozzle in the TBP and not a smooth rate of flow from looking at the gauge.

I recently faced an issue where the pump starts to pump once I hit the operating boost but then stops within a second! I moved the jumper to DFS and logged my car to see if there's any Inlet Air Temperature drop but there wasn't much as it used to be. Plus I've got a big amount of timing pull which tells me that there's not spraying into the engine!

I don't drive my car no more as there's no more joy with all this rubbish going on. All I do is drive it to only log it after a fix to see if there's any change.
