Default Reasons for no start???

I finally got my rebuilt engine in today. Everything's hooked up properly. There's fuel at the rail. All is good, but I get no crank when the key is turned. No relay click, nothing.

Give me some items to check. There's power to the starter, unless the starter relay died.
The car has been disassembled for nearly a year. Could this be EWS related? It's a 96. Built 6/96.

Thanks in advance.

First off I make an assumption the car ran before but you pulled the engine to get it rebuilt. These suggestions are only valid for that case.

Obvious but not to be overlooked
Battery 12 plus volts
voltage to the DME
voltage to the starter
DME relay
Fuel pump relay
Correct key when trying to start engine
You have a Schader valve at the end of your rail, it should be around 43 psi or so static pressure

EWS can always disable the start function but it should not if the right coded key is used...

Reportedly, the car ran before it was torn down. The PO started the rebuild then lost his nerve.

Battery voltage is fine.
How do I check V to the DME?
I got fuel pressure, so the relay is working.
The key that I got with the car (only one) was the key that the PO was using to drive the car.

From what I've read, this seems to be an EWS issue, but I'm looking for some secondary confirmation. When EWS is activated does the car not crank at all? Can I check for an EWS code with a code reader? I believe that the car was fitted with a BMW alarm, but I didn't get the keyfob with the car. I wonder if that's complicating things. Central locking doesn't work by the driver's door with the key or by the button on the center console.

Manually jump the poles on your starter with an insulated screw driver. Work?

Check whether the CEL light is on when you turn the key to the accessory position. If not, I would look into the EWS issue.

The CEL is on when the key is in accessory. I thought it was going to stay lit until the engine was running. That's how my E30 was...

so it's not turning over?

Sounds electrical for sure. We could probably tell you a bunch of things to check, but at the end of the day it's going to be you going over all the connections with a continuity checker / volt meter. Or I wonder if the ECU is somehow 'locked' much like when the code function is used on the OBC.

Good luck.

Did you check the connections to the starter? There is TWO red wires that go to the main post on the rear of the starter. I've messed that one up and ended up push starting my car.

Two red wires? Dammit. I connected 1 red wire which comes down from above the starter and a black wire that comes from the harness mid-engine under the intake.

Looks like this:

So I tried to start the car this morning, just for grins, and now the starter spins when I turn the key. It sounds like an electric drill running. It doesn't seem to engage the flywheel in order to turn the engine. I searched around a bit and it sounds like the the Bendix (the part that shunts the starter shaft out toward the flywheel) may have failed. Does anyone else have an experience with this? I'm hoping that there is a repair/rebuild option, rather than having to go find a new starter.

Options if ya got'em.

Thanks!
