No Crank, No Start, No Communication To Code Reader

No Crank, No Start, No Communication To Code Reader Hello a couple days ago i drove my 07 corolla to the gym and when i left some hours later the car only cranked but, didn't start. i tried checking for codes with my bluetooth code scanner but had a hell of a time getting it to talk to the car. At times, the vehicle would not start and makes loud knocking sound with lots of vibration but fails to start. after few attempts or waiting for some time say five minutes, if re tried, the engine starts. Connecting an obd ii scanner gives the code u0100 lost communication with ecm/pcm "a". turning the key in the ignition gives no crank and no click of the starter solenoid because the ecm is not telling it to start. With today's electronic controlled vehicles i highly recommend not using your vehicle to jump another and invest in a jump box. they are much cheaper than a new ecm.

Had a guy with a confirmed good ecu come out today, still nothing, no communication. checked fuses, swapped ipdms with another car. i had power going to the ecu in the connector, one always and 3 when key is on. I've seen some problems with the 9 pin connectors not communicating due to damaged or unseated pins. if your eml is flashing a 6 4 the problem is likely in the wiring to the engine or in the power up sequence of the modules. 2003 6.0l with no obdii communication that does not crank and does not start. the truck has had recurring (but intermittent) rough idle the past few years and after parking it in the garage one night she hasn't been able to run since. Got a used ecm that was badly totaled rear ended, but i did noticed that the check engine dose not turn on, when turning on the key in the case of the ecm, i ended up getting the same batch ecm as my original one (what are the chances).
