So today I went to look at a Gti today, on the positive side the body was completely rust free, but the engine is a different story. It would start and run for about 2-3 seconds and just die, the seller thinks it may be the oxygen sensor but to me it doesn't seem to be getting any gas. I search faithfully searched but I cant seem to dig up something with the same scenario, the last bit of information I can provide you with is the fact that the starter motor disengages before the engines dies.
