Hello, sorry for my first post being a cry for help, but I'm at a bit of a loss.
Background is that my partners MK7 1.6 CXXB golf has been diagnosed with bad injectors, and they wanted almost £3K / $4K. Thought i'd have a go at doing it myself, got the old ones out, sent them to be refurbished. Guy said all 4 looked bad, like water had been in the tank. He managed to refurbish them and sent them back to me.
So I drained the tank, changed the fuel filter and refilled with diesel. Refitted the injectors with new washers and seals ( and in the same order), torqued them down with new stretch bolts. Afterwards I hopped onto VCDS and ran the "Transfer fuel pump test" for 2 minutes or so.
Tried to crank it, and it spluttered to life briefly before dying again. Cranked a tiny bit more and there was no signs of life. I'm hesitant to just crank it to death 'cos I dont want to ruin the HPFP anymore than I already have, but does anyone have any ideas why its not bursting to life.
Things I've tried include
1. Checking and reseating the injectors. I cleaned the injector bores out prior and they look clean.
2. Checked all the fuel pipes, looks relatively dry.
3. Checked that fuel was actually going into the filter housing, looks good.
4. Took off the return lines to see if fuel was comign out, and it was.
Things I'm tempted to try but too nervous / unsure if theyll help:
1. Crack the lines going to the injector to see if fuel sputters out
2. Run the Transfer fuel pump test again for another 3-4 minutes to really ensure any air is out
3. Assume the fetal position and cry on the floor
If anyone has any brainy ideas as to what I'm missing or could be checking, let me know!
