First one

17978/P1570 - Engine Start Blocked by Immobilizer

Possible Symptoms
Engine starting but stalling immediately

Possible Causes
Key(s) not matched
Instrument Cluster not matched
Engine Control Unit (ECU) not matched
Engine Control Unit (ECU) Power Supply faulty

Possible Solutions
Match Key(s)/Instrument Cluster/Engine Control Unit (ECU)
Check Engine Control Unit (ECU) Power Supply (Relay


2nd one will probably be down to a bad connection on the coil. Clear the code and see if it comes back
