If you mean MAF, then yes. But with what little we know, it could be a LOT of things.

We KNOW some things:

The RCM is fine, as the car is cranking, so the ECR output of the RCM is OK. (Of course, the fuel pump or traction control relay or output could be bad. SO, IS the RCM ok?)
The Battery is probably fine, as the car is cranking and cranking (and sometimes even starts).
The pulse module, starter and solenoid are fine as well.
