Hello there đź‘‹
I have a 2003 BMW 530i that was hit in the front, nothing crazy. Replaced front end parts with parts from a donor vehicle, and it cranks, but doesn't want to start. Runs off starting fluid. After digging around I find out that no power is going to the fuel pump. Checked all the fuses throughout the vehicle, all in their designated spots and none blown. For some strange reason half of the fuse rail behind the glove box isn't getting power, and the OBDII port isn't working. But all other electronics in the car are working. I did some digging and found that the Fuse Distribution Block that sits under the Passenger Side (Right Side) Carpet is badly corroded. I would assume this is why half of the rail isn't getting power and the OBDII port isn't working. Sunday coming I'm also going to do the following:
-Test All Relays
-Test Camshaft Position Sensor
-Test Crankshaft Position Sensor
-Test EWS3 Security Module (I doubt this is the problem since it cranks)
-Test DME
-Check 20a Fuse By DME
-Inspect X183 Connecter For Corrosion (Sits Under Driver Side/Left Side Carpet)
-Replace Fuse Block Under Passenger Side Carpet Because Of Corrosion
-Test MAF Sensor
-Check Positive Battery Terminal To See If Airbag Battery Safety Sensor Blew
Other than those things, any pointers? Any help would be appreciated!
