Hi my name is ***** ***** I will be happy to assist with this today.In some cases I may need more info to assist better.I apologize for any delay.My info is somewhat limited on your model here but I had seen no one else has responded and would like to see if I can help here.If at any time you feel that I cannot help with this please let me know.
The trunk sensor acting up wont cause a no start issue here.It should still start.The trunk sensor issue though is usually a fault with the position sensor which is usually part of the trunk latch itself with it needing replaced.
If you hear the relay working when trying to start and you have no crank over from the starter itself this issue can be with the starter needing replaced.The starter can fail suddenly and causes this fault here.I have had to replace several starters in the past before for this issue.
The signals need tested to the starter to verify that this is the cause.
If you bought this certified you might check with the facility you bought it from to see if they will cover the costs for diagnosis and repair on this as some facilities will do.
