Swift GTI Problem

moin people have volgendes problem, bought me yesterday a ’95 GTI. where I tried it, the actually normal started, when I drove for a few minutes and made out to look at the car and then wanted to start again he only jumped after a while. so when the car is running the 1A. where I then drove home and the car drove so 80 km and then I took a break the danahc did not jump, had to look at and now it doesn’t jump any more with push, but I have tried it out. I have installed new spark plugs today but still didn’t help anything. what could that be? I already thought that I would completely re-ignite the ignition just make new ignition cables and dividers and so. who can help me? best then also on the side where I can buy the parts. many thanks already
