I got one hell of a problem with my 91 190e 2.6. Me and my dad were fixing a fuel leak on the fuel pump line (the line between the two pumps) while it was running. The car suddenly shut off. We couldn't get it to start. We checked for power but there was no juice at the pump connector. Well I thought it was the ovp but I'm getting power outta pin 30 on the ovp. If I remember right that runs to pin 87 on the fuse box where the fuel pump relay sits. No juice over there. So next thought was the fuse box. Found a good one and put it in but no change. So next thought was the relay. Swapped it but there was no change. All the wires that connect are good, I checked them with a ohm meter. I did the test on the ovp and according to that test its bad. Like I said I'm getting power out of it so Idk about that. I jumped pin 30 and 87 on the relay slot and the pumps don't kick on. What the heck am I missing?

Try removing the MAS relay & jumping pins #1 to #2. That should make the pumps run
