1991 300SEL, changed fuel filter, started car to inspect for leaks and found one. Turned car off and tighted the banjo fitting on the filter. Started car again, leak was less so I tighted it some more, while car was running. Still a little drip from the fuel pump banjo fitting. I thought to tighted bango fitting on the pump, (I thought to myself did I loosen it while removing the filter?), wrench touches something on the pump, pump stops, car dies, will not start again, rats I have screwed up.
What is my punishment? Could the fuel pump relay be the problem, fuel pump perhaps. Tell me a fuse is blown somewhere?
I feel like an idiot.
