Engine Performance problem
1985 BMW 735 6 cyl Two Wheel Drive Automatic 220456 miles
So after changing the torque converter, the car won't start.
It cranks, there is spark, but no fuel coming from the fuel pump.
It has: a new transfer pump, new sending unit, new fuel pump, new fuel pump relay, new main relay, new crankshaft position sensors, (both sensors at the tranny).
We tested the airflow meter, and it is okay.
When I jump the #30 and #87 terminals of the fuel pump relay, I can hear the transfer pump running, but not the fuel pump. I finally got under the car while my friend turned the key, tested the terminals at the fuel pump, and it has no voltage with the key in the ON position, but briefly while the car is actually cranking.
At this point I am thinking the thermo-time switch or the cold start valve. Also I have hear it could be the ignition switch.
Do you have any ideas. I have been working on this car for a year, and am really getting frustrated.
Any ideas would be great. Thanks in advance.
have the same problem?
