Injectors not pulsing...no start

[SpeedWiz]

So I recently bought a 325es that had been converted to I components,
The engine will currently not start because the injectors will not pulse therefore no fuel in the cylinder

I have spark
Car fires with starter fluid
Checked the CPS good reading
Fuel in the fuel rail with good pressure
power at the injectors
No oxygen sensor hooked up (shouldnt matter)
Temp Sensor good

Any Ideas?

No connection between ECU and injectors?

Blown ecu?

If you've got power to the injectors AND the ECU will run the ignition,
(since it will run on starter fluid)

there's not a lot else it can be...

By I components, you mean head, intake, harness, etc.?

Did you do a noid light test?

[SpeedWiz]

I have four ecu that I have been switching out..

And I just changed the wire harness and same problem..

Gonna change injectors today

[SpeedWiz]

Will do a Noid test today too

With what you have checked and what you tried it sounds to me like you may have a harness problem. Ohm out the injector control circuit wires.

I would suspect the c191 injector harness plug under the intake manifold but like others have said a noid light on the injectors would be the easiest way to tell if they are firing
