No, loose cables would not cause the problems described. When the battery is disconnected, the PCM loses its memory and when restarted, the PCM does not detect anything and woulsd run well but when the problem of the bad PCM is detected the CEL would come on and the difficult starting would occur.
If you remove the PCcover, you might notice some stains due yo leaking capacitors and that would cause PCM errors.
When fuel pressure is low due to internal leakages, it would affect initial starting but when pressure is achieved, starting and running would not be affected much as the pump is running at a very high pressure and it can overcome the leakes of the fuel filter housing as it is minimal.
