2002 gti le 718 engine I replace 2 new pistons and rigns and all gaskets, Ign coil with wires, spark plugs. Compression reads 150 psi on both cyl. It starts up but only runs for 5-10 seconds then shut off. I keeps cranking but it dont want to start. After taking out the spark plugs and clean it with starting fluid and reinstall them, it will run for 5-10 seconds then shuts off. same thing keeps happening. It seems to be fouling out the plugs all the time. Please if anyone have any idea whats going on, please help me thanks.
