'87 ETA, no fuel or spark

07-09-2014, 10:44 AM

1987 325e with manual trans. Came in with a no start condition. I have replaced the following:

-reference sensor and speed sensor (in the trans)
-main relay
-fuel pump relay
-OBC relay (under the dash)
-fuseable link
-battery
-027 DME

What else could I be missing? It has good compression and if I manually ground out the fuel pump relay, I hear it turn on.

Thanks!

Check to see if the DME is getting a START signal from the ignition.

The car makes it possible, but the driver makes it happen.

Changed ignition switch and AFM from a known good car, still nothing.
