 Engine shakes real bad then dies
My 97 318ti will start for a few seconds but shakes real bad then dies. The technician cannot read any codes from the data link connector under the hood because there seems to be no power any more to the data link for the computer to work.
My car is a 97 318ti but it does NOT have an OBDII connector under the dash. Instead it has a large, round connector under the hood which is where the mechanic is attaching the computer link cable. It is a foreign (Japanese) car that was imported to New Zealand so this may explain why there is no OBD2 connector???
When the car was first taken in to the shop the data link connector was working fine. When the computer was first hooked up and the codes read it indicated a bad cam sensor, then bad MAF - both were replaced. Then it would start and shake real bad and die. The BMW dealerships computer stopped reading codes for some reason which is now what they are troubleshooting. Until they can read the error codes they can't get back to diagnosing the running problems.
Prior to the data link connector not working the codes indicated bad cam sensor and bad MAF. I have replaced those parts as well as the spark plugs. The BMW dealership is stumped and is now checking each wire for continuity which is slow and expensive.
Any ideas out there? |
