Hi friends. 1993 300e 2.8. My original OVP went bad. The car had hard start problems and frequent electrical components going on and off. I installed the OVP relay, part # 201 540 32 45. However, I was wrong. That OVP started the car, but it wouldn't let the vehicle shut off even with the key. I ended up finding a master key, and it finally shut off, also had been disconnected from the battery for 5-10 minutes. I then replaced the OVP with a new and correct part # 000 540 67 45, and now the car cranks but won't start. Is there anything that could've gone wrong during this process? I need help troubleshooting.
OVP is OEM brand new, correct match for VIN.
The wiring harness is updated
Fuel pumps still engage in key position 2 (so I don't think the Fuel Pump Relay is bad).
