2005 R52 Battery reversed. Engine turns but won't start, fuel pump does not prime.
Hi everyone. I haven't used the car in a while and went to start it up this morning. Battery was dead due to inactivity.Disconnected the battery terminals and used jump leads to connect terminals to an exterior battery but inadvertently connected to the wrong terminals on the exterior battery for just a second. Battery connected backwards. Now, car will not start. The engine turns, but I don't hear the fuel pump kicking in and the temperature gauge is stuck on high. Checked all fuses in footwell, and fusebox in the engine compartment including the larger fuses on the underside of that fusebox. All seem OK. Could it be that the regulator is blown and polarity could be reversed on the alternator? Would that also cause the fuel pump to stop working?
