2001 Volkswagen Golf VW Golf 4 2l

Hi. My car drove fine, parked it and wouldnt start again. It swings strong but will not start. Fuel pump kicks in. Injectors are pulsing. Sparkplugs firing. All fused in order and instrument cluster lights also works fine. I checked the wiring loom from coil up to plug on left front fender for possible breaks in wires and all seemed fine. I lightly tugged on a few wires in the loom in the corner next to battery that splits to coil and interior and the car started fine a few times. Even drove it and all was good. After a while of standing the car did the same thing. I did the same as before lightly tugging on the same wires and again the car only swings strong but dont start. Checked wires running to coil with ohm meter for continuation andthat was fine. Lightly tugged on wires again and the car started but it idles like its over fueling and also smells very rich while idling.I am out of ideas and frustrated. Need a new approach please assist
