I have a 97 318ti automatic. I had the same problem. All lights on no crank. Changed starter because I thought it was bad. Not the starter. After a week of fiddling with it I gave up and called my indie. Was just about to call for the tow truck and decided to check one more thing. There is a ground wire under the car that grounds the engine to the frame. I figured I would go under the car, take it off, clean the contacts and see if that would help. Low and behold, to my surprise, I found that the sway bar mount, that the wire was attached to, was completely broken off the frame and floating; hence no contact. Put a brace under the bracket and let it down to make contact and it started right up. Got out my mig and spot welded it and took it to a body shop to have it welded. So before ripping into the starter or EWS check that ground wire. I also changed starter from top of engine. did not have to remove lower intake only top half. If anyone wants to know how I did it email me.

there is a ground wire under the car on the front right. it is connected to the stabilizer mount. see if it is still connected or rotted off also check the mount if it is rusted off and not touching the frame. the ground stap grounds the engine to the frame.

Take these two thicker wires and connect them together by striping and soldering them or using a T-Tap connector (My favorite and easiest). This will only bypass the EWS starter kill. EWS will still be active for ignition and fuel. If the DME ISN does not match EWS stored ISN then no fuel or spark.

This will eliminate the EWS starter kill by bypassing the start relay.

If you turn on the key with all wiring on the starter and a good ground to the starter body, jumper #1 to #2 and that will energize the starter solenoid and the starter should engage the bendix and start rotation.

You should not get any fuel pressure until the DME detects the engine is rotating, so until the engine is cranking over and the crank position sensor detects rotation the fuel relay will not engage sending power to your fuel pump.



Hope this helps, John S
I have a similar issue after installing a supercharger kit but mine turns over just no spark or fuel pump working..
